Question (Category: homework )
1. Label each of the following as an acid, base or salt, explaining your answer: a. BaCl2 b. Ca(OH)2 c. HClO4 d. CrI6 e. HC2H3O2 2. Calculate the pH of the following solutions with the given [H+] or [OH-] and indicate whether it is an acid or base: a. [H+] = 0.0001 b. [OH-] = 0.01 c. [H+] = 0.000001 3. Calculate the molarity of the following solutions a. 40 grams of Na3PO4 dissolved to make 400 ml of solution b. 40 grams of C6H12O6 dissolved to make 300 ml of solution 4. Calculate the molarity of the following solutions from this acid-base titration data: a. If 250 ml of Ba(OH)2 of unknown concentration with a methyl red indicator present is titrated with [0.325 M] HNO3, the yellow solution turns red after 36.4 ml of the HNO3 is added. What is the molarity of the Ba(OH)2 solution? b. If 150 ml of HNO3 of unknown concentration with a methyl orange indicator present is titrated with [0.163 M] KOH, the red solution turns yellow after 28.9 ml of the KOH is added. What is the molarity of the HNO3 solution?
