Hi, I was just looking at that and this is what I came up with: so I would need a high concentration of CrO42- to precipitate BaCrO4 and I can increase the concentration of CrO42- by lowering the concentration of H+ by adding NaOH so it will neutralize the H+. This way my equilibrium will shift...

Sure, if I knew how to that is...:)

Wait...but then it wouldn't balance...

2CrO42- <--> Cr2O72- + 3H2O + 2OH- thanks, ...so I could just write the equation like this?

Homework Statement Hi everyone, I'm trying to finish my lab report but I'm stuck on this question and don't even know how to start it. Could anyone let me know how to board it or a starting clue? I'm given these two equations 1. BaCrO4 (s) <---> Ba2+ (aq) + CrO42- (aq) 2. 2CrO42-...

4 H2O?

Hello, I'm having problems with the same question...is this right? 2CrO42- + 2H3O + 2OH- <--> Cr2O72- + 3H2O + 2OH-
