Calculate the molarity (mol/L) of CO32- when SrCO3 is placed in a 0.0340 M SrCl2 solution. The equation represents the solubility process.
SrCO3 (s) <----> Sr2+ (aq) + CO32- (aq)
An unknown metal hypochlorite salt, M(ClO)2, is subjected to analysis by iodometric titration: the salt is dissolved in dilute sulfuric acid, treated with excess aqueous KI,and then titrated with Na2S2O3.
