WebMay 7, 2024 · Ag2CrO4(s) ⇌ 2Ag+ +CrO2− 4 Explanation: Now we have Ksp = [Ag+]2[CrO2− 4], and if we call the solubility of silver chromate under the given conditions S, then, by the given stoichiometry, we write.......... Ksp = (2S)2 ×S = 4S3 And thus S = 3√ 1.9 × 10−12 4 = 7.80 ×10−5 ⋅ mol ⋅ L−1. And thus SAg+ = 15.6× 10−5 ⋅ mol ⋅ L−1; WebOct 18, 2015 · CrO2− 4 So, start with the silver cations. Notice that you have one silver cation on the reactants' side and two on the products' side. Multiply the silver nitrate by 2 to get 2AgNO3 (aq] + (NH4)2CrO4 (aq] → Ag2CrO4 (s] ⏐↓ + NH4NO3 (aq] Now look at the ammonium cations. i strive to be my authentic self
