1. A titration is performed. 13.2 mL of 2.7 M HCl was required to titrate 25.0 mL of NaOH to the equivalence point. What is the molarity of NaOH at the equivalence point?
2. The rate law for a reaction is rate = k[A][B]. What is the reaction order with respect to reactant A?
3. You mix 40 mL of 0.02 M KIO3 with 10 mL of 0.01 M sulfite-starch solution in 70 mL of water. What is the initial concentration of KIO3 in the reaction mixture?
