Common Ions and Their Charges
Common Ions and Their Charges A mastery of the common ions, their formulas and their charges, is essential to success in AP Chemistry. You are expected to know all of these ions on the first day of class, when I will give you a quiz on them. You will always be allowed a periodic table, which makes indentifying the ions on the left “automatic.” For tips on learning these ions, see the opposite side of this page.

A Theoretical Study on the Reaction of Ozone with Aqueous Iodide

Montes, Universidad Politécnica de Madrid, 28040 Madrid, Spain. Correspondence to O. Gálvez (Email: [email protected]) Abstract Atmospheric iodine chemistry plays a key role in tropospheric ozone catalytic destruction, new particle formation, and as one of the possible sinks of gaseous polar elemental mercury. Moreover, it has been recently proposed that reaction of ozone with iodide on sea surface could be the major contributor to the chemical loss of atmospheric ozone. However, the mechanism of the reaction between aqueous iodide and ozone is not well known. The aim of this paper is to improve the understanding of such mechanism. In this paper, it is presented an ab initio study of the reaction of aqueous iodide and ozone, evaluating thermodynamic data of the different reactions proposed in previous experimental studies. In addition, the structures, energetics and possible evolution of the key IOOO- intermediate are discussed for the first time. 1. Introduction Atmospheric iodine chemistry has received special attention in the last decades (see Saiz-Lopez, Plane et al. 20121 and references therein), since it plays a relevant role in tropospheric ozone catalytic destruction2, 3 and new particle formation.4 Moreover, in the polar atmosphere, iodine has also been suggested as one of the possible sinks of gaseous elemental mercury.5 Ozone is a key atmospheric molecule.

You should recognize quickly the symbols (name them) and their positions on the Periodic Table of the first 20 elements. The last page of this packet has a Periodic Table for your reference. Memorize the list of sixty familiar ions. You should be able to write the symbol of the ion given the name, and vice versa. • Included in this packet are: (1) a list of ions by name, (2) a list of ions by grouping, (3) ion flash cards, and (4) four practice ions quizzes. • You should be able to complete the ions quiz in less than four minutes without trouble. (Basically you need to know your ions better than you know your multiplication table.) • There will be a quiz in the first week of school. • You may want to print out and cut the flashcards of the ions, and then arrange them by groups based on patterns you observe. (For example, which ones are made of only one element / several elements? Which ones have positive charges vs. negative charges? If it’s an ion from a single element, where are they on the periodic table? Which ones have several possible charges? How are they named, e.g. –ium, -ide, -ate, -ite, hypo-, per-, bi-, thio-, -ous, -ic?) Learn every topic. Refer to the list of Review Topics. These are all the concepts and skills that you are expected to have learned during your first year of chemistry and that you can do with ease.

EXPERIMENT 6 Chemistry 110 Lab WRITING and NAMING CHEMICAL FORMULAS
EXPERIMENT 6 Chemistry 110 Lab WRITING AND NAMING CHEMICAL FORMULAS PURPOSE: The purpose of this lab is to write the names and formulas of chemical compounds so that eventually the students will be able to write complete balanced chemical equations. I. INTRODUCTION So far you have learned what a chemical symbol is. For example, Pb is the symbol for the element lead. Elements are not often found pure in nature. Most elements are chemically combined in a definite ratio with other elements. These types of substances are called compounds. Most of the earth’s hydrogen is not in the form H2, but is in water in the form H2O. Just as elements have symbols, compounds have formulas. It is very important that a chemistry student learn how to name formulas and learn to write the correct formula from a given name. The elements in a compound are in a definite or set ratio. Water is always H2O, never anything else. The ratio is always 2 hydrogens to 1 oxygen. This definite composition is what makes compounds unique from mixtures. In experiment 5 you learned that a mixture of two substances can be in any ratio or proportion. Chemistry is largely about describing chemical reactions and predicting their results. In order to correctly write a chemical equation we must first learn how to write and name chemical formulas. For example, we may be given a reaction in sentence form: When aqueous silver nitrate reacts with aqueous sodium chloride a precipitate silver chloride is formed and the sodium and nitrate ions remain in solution.

The rate equation was obtained, that is, rate-k[I3-][HCOO-]/([I"]+b), where k and b were as follows: at 25-C, k-0.334× 10~2 min-1, b-d.19×10-3 M; at 30-C, k-0.536×10-2 min-1, b-1.71×10-3M; at 35oC, k- 1.21× 10-2 min-1, b-1.84× 10-3 M. b is a good agreement with the equilibrium constant for Ia~ *I2+I~. The activation energy of this reaction was 21 kcal. The mechanism of this reaction and the intermediate complex were discussed.
