For binary salts (like AgCl, AgBr) sp s K Solubility of AgCl = 30 1.8 10 x 5 1.34 10 mol / L x Solubility of AgBr = 23 5.0 10 x 7 7.1 10 mol / L x For Ag₂CrO₄, Ksp = 4s3 Solubility of Ag₂CrO₄ 12 sp 3 15 3 3 5 K 2.4 10 600 10 4 4 8.44 10 mol / L x x x As Ag₂CrO₄ bas maximum solubility, it will give maximum Ag⁺ ions in solubility. Hence, it will be used.
