Sorry class, the test is tomorrow. You are more prepared than you think. Titration will not be on the test. From unit 1, focus on empirical formula, % composition limiting reactants, and % yield. From Unit 2, focus on how electrolytes dissociate in water, identifying if a substance is soluble or insoluble from solubility tables, neutralization reactions, precipitate reactions, redox reactions (and for all three types writing the molecular reaction and the net ionic reaction.) and molarity. ON the test you will have a question similar to your lab report calculations, a question like #28 on the homework packet, and you will have to explain how to create a solution of certain molarity from mass and dilution, just like we did in class the other day. When reviewing HW packet #1, focus on ?s # 3,5,9,10,11,12,14,16 and 17. From packet #2, focus on ?s #1,2,5,7-11, 14-16,19 and 28.
