Tutorial 2 FORMULAS, PERCENTAGE COMPOSITION
T-6 Tutorial 2 FORMULAS, PERCENTAGE COMPOSITION, AND THE MOLE FORMULAS: A chemical formula shows the elemental composition of a substance: the chemical symbols show what elements are present and the numerical subscripts show how many atoms of each element there are in a formula unit. Examples: NaCl: one sodium atom, one chlorine atom in a formula unit CaCl2: one calcium atom, two chlorine atoms in a formula unit Mg3N2: three magnesium atoms, two nitrogen atoms in a formula unit The presence of a metal in a chemical formula indicates an ionic compound, which is composed of positive ions (cations) and negative ions (anions). A formula with only nonmetals indicates a + molecular compound (unless it is an ammonium, NH4 , compound). Only ionic compounds are considered in this Tutorial. There are tables of common ions in your lecture text, p 56 (cations) and p 57 (anions). A combined table of these same ions can be found on the inside back cover of the lecture text. A similar list is on the next page; all formulas needed in this and subsequent Tutorial problems can be written with ions from this list. Writing formulas for ionic compounds is very straightforward: TOTAL POSITIVE CHARGES MUST BE THE SAME AS TOTAL NEGATIVE CHARGES. The formula must be neutral. The positive ion is written first in the formula and the name of the compound is the two ion names. EXAMPLE: Write the formula for potassium chloride. The name tells you there are potassium, K+, and chloride, Cl–, ions. Each potassium ion is +1 and each chloride ion is -1: one of each is needed, and the formula for potassium chloride is KCl.

Managing Potassium for Organic Crop Production by Robert Mikkelsen an Adequate K Supply Is Essential for Both Organic and Conventional Crop Production
NORTH AMERICA Managing Potassium for Organic Crop Production By Robert Mikkelsen An adequate K supply is essential for both organic and conventional crop production. Potas- sium is involved in many plant physiological reactions, including osmoregulation, protein synthesis, enzyme activation, and photosynthate translocation. The K balance on many farms is negative, where more K is removed in harvested crops than is returned again to the soil. An overview of commonly used K fertilizers for organic production is provided. otassium is an essential nutrient for plant growth, but it often receives less attention than N and P in many crop Pproduction systems. Many regions of the U.S.A. and all of the Canadian provinces remove more K during harvest than is returned to the soil in fertilizer and manure (Figure 1). In the U.S.A., an average of only 3 units of K is replaced as fertilizer and manure for every 4 units of K removed in crops, resulting in a depletion of nutrients from the soil and increasing occur- rences of deficiency in many places. Potassium is the soil cation required in the largest amount by plants, regardless of nutrient management philosophy. 1,400 Removal 1,200 Hay and forage crops can remove hundreds of pounds of K from the soil Manure each year, placing a heavy demand on soil resources. 1,000 Fertilizer Large amounts of K are required to maintain plant health 800 and vigor. Some specific roles of K in the plant include os- moregulation, internal cation/anion balance, enzyme activa- 600 tion, proper water relations, photosynthate translocation, and 400 protein synthesis.

Writing Total and Net Ionic Equations
WRITING TOTAL AND NET IONIC EQUATIONS http://www.csun.edu/~hcchm001/FreshChemHandouts.html 1. Write the overall equation including the correct designations for the physical state of the substances (s, l, g, aq). Balance this equation. Most of these kinds of equations are double displacement reactions: AX + BY 6 AY + BX 2. For the total ionic equations, write strong electrolytes in solution in the form of aqueous ions. (a) Strong acids. The common strong acids and their aqueous ions are: HI Hydroiodic acid H+-(aq) + I (aq) HBr Hydrobromic acid H+-(aq) + Br (aq) HCl Hydrochloric acid H+-(aq) + Cl (aq) +- HNO33Nitric acid H (aq) + NO (aq) +- HClO44Perchloric acid H (aq) + ClO (aq) +-2 H24SO Sulfuric acid 2 H (aq) + SO4(aq) (b) Strong bases. Strong bases are the hydroxides of the alkali (Group IA) and alkaline earth (Group IIA) metals ions which are sufficiently soluble. The common strong bases and their aqueous ions are: LiOH Lithium hydroxide Li+-(aq) + OH (aq) NaOH Sodium hydroxide Na+-(aq) + OH (aq) KOH Potassium hydroxide K+-(aq) + OH (aq) +2 - Sr(OH)2Strontium hydroxide Sr (aq) + 2 OH (aq) +2 - Ba(OH)2 Barium hydroxide Ba (aq) + 2 OH (aq) (c) Soluble salts. Determinations of the solubility of a salt may be made by reference to SOLUBILITIES OF IONIC COMPOUNDS. Soluble salts are written as their aqueous ions: NaCl(aq) Sodium chloride Na+-(aq) + Cl (aq) +-2 K24SO (aq) Potassium sulfate 2 K (aq) + SO4(aq) +-2 Li23CO (aq) Lithium carbonate 2 Li (aq) + CO3(aq) +-3 Na34PO (aq) Sodium phosphate 3 Na (aq) + PO4(aq) +-2 (NH42) SO4(aq) Ammonium sulfate 2 NH4(aq) + SO4 (aq) 3.

AP Chemistry Free Response
AP Chemistry Exam Reactions: Questions and Answers With the new format of the exam in 2007 and the availability of both questions and answers on the web at AP Central (http://apcentral.collegeboard.com:80/apc/public/courses/4606.html), I have determined not to update this page any longer. Please create an account as a teacher at AP Central and navigate to the full exams and scoring rubrics which are available back to 2003 Beginning in 2007, question 4 is no longer 5 out of 8 responses but rather three required responses. Also, in addition to writing the reactants and products, the equation must be balanced and there is a question about the chemical reaction. 2007 (a) A solution of sodium hydroxide is added to a solution of lead(II) nitrate. If 1.0 L volumes of 1.0 M solutions of sodium hydroxide and lead(II) nitrate are mixed together, now many moles of product(s) will be produced? Assume the reaction goes to completion. (b) Excess nitric acid is added to solid calcium carbonate. Briefly explain why statues made of marble (calcium carbonate) displayed outdoors in urban areas are deteriorating. (c) A solution containing silver(I) ion (an oxidixing agent) is mixed with a; solution containing iron(II) ion (a reducing agent). If the contents of the reaction mixture described above are filtered, what substance(s), if any, would remain on the filter paper? - 2+ → (a) (i) Balanced equation: 2OH + Pb Pb(OH)2 (s) (ii) The moles of each reactant are obtained by multiplying the volume times the molarity.

POTASSIUM (K) Why Do My Plants Need Potassium? K Is the Most Important Element in Water Regulation Which Also Aids in Wear Tole
Extension Education Center 423 Griffing Avenue, Suite 100 Riverhead, New York 11901-3071 t. 631.727.7850 f. 631.727.7130 POTASSIUM (K) Why do my plants need potassium? K is the most important element in water regulation which also aids in wear tolerance and cooling. Insufficient K also leads to the potential for low temperature injury in late winter when food reserves are low. K is important in preventing salt stress. Can potassium fertilizer burn my turf? Usually muriate of potash (KCl) in fertilizer has a high burn potential. Potassium sulfate has a lower burn potential, releases K more gradually than muriate of potash, and is a better choice for quality turf areas. Potassium sulfate is preferred if large amounts have to be added because it is less likely to burn but it can also decrease pH. It is always wise to irrigate after any granular, salt type of potassium applied at the following levels: over 0.33 pounds/1000 square feet on close cut turf, and over 0.5 pounds/1000 square feet on high cut turf. Do not make applications just before freezing weather because freezing concentrates potassium in soil. Why do I need to add potassium fertilizer? Major amounts of K are lost when clippings removed, especially if using muriate of potash as your K source. K also readily leaches in sandy soils. Acidic soils tend to be potassium deficient. How much potassium should I add? Look for K number in N-P-K label that is half of N number. You can also spoon feed small quantities, 0.1-0.5 lb/1000square feet, particularly in summer to enhance wear tolerance and turf health.

PSC Technical Advisory Panel Report.Pdf
National Organic Standards Board Technical Advisory Panel Review compiled by University of California Sustainable Agriculture Research and Education Program (UC SAREP) for the USDA National Organic Program Potassium Sulfate for use in crop production Executive Summary1 The following petition is under consideration with respect to NOP regulations subpart G, governing the inclusion of substances on the National List of Allowed and Prohibited Substances: Petitioned: Addition of potassium sulfate to section 205.601(j), “Synthetic substances allowed for use in organic crop production as plant or soil amendments.” Potassium sulfate is a source of highly soluble potassium, and has the additional benefit of supplying sulfur. It is used in agricultural production systems where potassium is a limiting nutrient and also as a substitute for potassium chloride on chloride- sensitive crops. The NOP has no prior ruling on the use of the substance. The nature of the petitioned substance is highly debatable. Naturally occurring potassium sulfate is not subject to the TAP review process because “naturally-occurring” substances are implicitly allowed for use in organics. The intended sourcing of the petitioned form of potassium sulfate, however, brings into question the interpretive distinctions between a “synthetic” and a “non-synthetic” under organic law. According to the petitioner, the product “should not be treated differently than product produced from natural brines” since it is produced from naturally occurring minerals. The crux of the decision to grant the petition rests on how one chooses to interpret this equivalency claim. All TAP reviewers agreed that the petitioned substance should be considered synthetic. In general, the reviewers also agreed that it should be restricted as a soil adjuvant.
