Question 1

What is the molarity of a potassium triiodide solution, KI3(aq), if 30.00 mL of the solution is required to completely react with 25.00 mL of a 0.200 mol L-1 thiosulfate solution, K2S2O3(aq)? The chemical equation for the reaction is

2S2O32-(aq) + I3-(aq) → S4O62-(aq) + 3I-(aq)

◦ 0.120 mol L-1
◦ 0.333 mol L-1
◦ 0.0833 mol L-1
◦ 0.167 mol L-1

Question 2

Based on the balanced chemical equation shown below, determine the molarity of a solution containing Fe2+(aq) if 40.00 mL of the Fe2+(aq) solution is required to completely react with 30.00 mL of a 0.250 mol L-1 potassium bromate, KBrO3(aq), solution. The chemical equation for the reaction is
 
6Fe2+(aq) + BrO3-(aq) + 6H+(aq) → 6Fe3+(aq) + Br-(aq) + 3H2O(l)

◦ 1.12 mol L-1
◦ 0.0312 mol L-1
◦ 0.188 mol L-1
◦ 2.00 mol L-1
