Recognize neutralization reactions Review law of conservation of mass: predicting products and balancing reactions Demos: cabbage juice neutralization reaction pH probe MOM demo Apr 2211:50 AM 1 neutralization.notebook May 02, 2016 Review What are the rules for naming binary acids? What are the rules for naming oxyacids? Name these acids: Write these formulas H S 2 perchloric acid H2SO4 chloric acid hydrochloric acid H2SO3 chlorous acid Name these bases: NaOH Al(OH)3 mr. glanes Apr 2212:59 PM 2 neutralization.notebook May 02, 2016 Which reactions are double replacement? Why? 1) 3Fe(OH)2 + 2H3PO4 → Fe3(PO4)2 + 6HOH 2) Pb(NO3)2 + 2KI → PbI2 + 2KNO3 3) 2NH4OH(aq) + H2S(aq) → (NH4)2S(aq) + 2H2O(l) 4) 2 HCl + Zn → ZnCl2 + H2 Which reactions are neutralization of acid and base? How do you know? Neutralization reactions 1. are a type of double replacement reaction 2. reactants must be ACID and BASE What are the products? answers: double replacement reactions: # 1,2,3 neutralization reactions: #1 and 3 Apr 235:36 AM 3 neutralization.notebook May 02, 2016 Neutralization reactions 1. are a type of double replacement reaction 2. reactants must be ACID and BASE 3. the products are WATER and SALT. (an ionic compound) NaOH + HCl H2O + NaCl base + acid water + salt another example: Ca(OH)2 + H2SO4 2H2O + CaSO4 Apr 235:35 AM 4 neutralization.notebook May 02, 2016 Write the reactant formulas, then predict the products and balance Zinc hydroxide and sulfuric acid → potassium hydroxide + chlorous acid → carbonic acid and strontium hydroxide è Answers: Zn(OH)2 + H2SO4→ ZnSO4 + 2HOH(l) KOH + HClO2 → KClO2(aq) + HOH(l) H2CO3 + Sr(OH)2 + → SrCO3 + 2HOH(l) Apr 2312:51 PM 5 neutralization.notebook May 02, 2016 Neutralization Apr 235:29 AM 6 neutralization.notebook May 02, 2016 more practice iron(II) hydroxide + phosphoric acid → ammonium hydroxide+ hydrosulfuric acid→ answers: 3Fe(OH)2 + 2H3PO4 → Fe3(PO4)2 + 6HOH(l) 2NH4OH + H2S →/(NH4)2S + 2HOH(l) Apr 2310:05 PM 7 neutralization.notebook May 02, 2016 II. For each of the following salts, tell which acid and based formed it. Salt Acid Base Zn(NO3)2 Al(ClO)3 NaCl Ca3(PO4)2 NH4C2H3O2 III. Give the formula and the name for the salt produced from the following acids and bases. 1. nitric acid and sodium hydroxide salt name: salt formula: 6. permanganic acid and rubidium hydroxide salt name: salt formula: Apr 239:57 PM 8.
