Answer the following questions regarding this system. The solubility product constants (Ksp) for BaCrO4 and BaC204 are 2.10 x 100 and 1.30 x10-6, respectively A) Which barium salt will precipitate first? BaCrO4 BaC204 B) What concentration of Ba2 must be present for BaCrO4 to begin precipitating? Number c) what concentration of Ba2+ is required to reduce oxalate to 10% of its original concentration? Number Ba What is the ratio of oxalate to chromate ([C2042 V[CrO4) when the Ba2 concentration is 0.0040 M? Number G Previous ⧠Give Up & View Solution Check Answer Next Exit Hint
