Radiochemical techniques are useful in estimating the solubility product of many compounds. In one experiment, 50.0 mL of a 0.010 M AgNO3 solution containing a silver isotope with a radioactivity of 74025 counts per min per mL were mixed with 100 mL of a 0.030 M NaIO3 solution. The mixed solution was diluted to 500 mL and filtered to remove all of the AgIO3 precipitate. The remaining solution was found to have a radioactivity of 44.4 counts per min per mL. What is the Ksp of AgIO3?
When solutions containing silver and chloride ions are mixed, silver chloride precipitates: Ag+ (aq) plus Cl- (aq) ---> AgCl(s)
