Solid, soluble silver nitrate is added slowly to a solution for which the initial concentrations of Cl? and CrO42? were [Cl? ]0 = 0.020 mol L?1 and [CrO42? ]0 = 0.0050 mol L?1. (a) Calculate [Ag+] when a precipitate first appears and identify the precipitate. The Ksp values for AgCl(s) and Ag2CrO4(s) are 1.8×10?10 and 1.1×10?12, respectively. (b) Calculate [Cl? ] and [CrO42? ] just before the second precipitate is formed. What is the % efficiency of the separation? (i.e. If X represents the anion that precipitates first, then what fraction of X was precipitated from the solution at the instant the second precipitate starts to form?)
