c. Ba(OH)2 d. H3PO4
2. Calculate the pH of the following solutions with the given [H+] or [OH-] and indicate whether it is an acid or base:
a. [OH-] = 0.01
b. [H+] = 0.001
c. [OH-] = 0.00001
3. Calculate the molarity of the following solutions
a. 25 grams of KNO3 dissolved to make 300 ml of solution
b. 50 grams of C5H10O5 dissolved to make 400 ml of solution
4. Calculate the molarity of the following solutions from this acid-base titration data:
a. If 200 ml of NaOH of unknown concentration with a methyl red indicator present is
titrated with [0.250 M] H2SO4, the yellow solution turns red after 40.5 ml of the H2SO4
is added. What is the molarity of the NaOH solution?
b. If 300 ml of H2SO4 of unknown concentration with a methyl orange indicator present
is titrated with [0.200 M] Mg(OH)2, the red solution turns yellow after 30.6 ml of the
Mg(OH)2 is added. What is the molarity of the H2SO4 solution?
