Question
1) A saturated solution of the slightly soluble salt MA3 is 1.4 ×10^–3 M in MA3. What is its Ksp value?
2) A 20.0 mL sample of NaIO3 was treated with an excess of KI and HCl and the iodine produced titrated with 0.05125 M Na2S2O3. 19.35 mL of Na2S2O3 solution were required to reach a starch‐iodine endpoint. What was the concentration of the NaIO3?
