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- (aq) + 2H+ (aq) <----> Cr2O72- (aq) + H2O (l)
Question: How would you precipitate BaCrO4 from a solution of Ba(NO3)2 and K2Cr2O7 ? And I need to show it in chemical equations.
The Attempt at a Solution
I honestly have no clue...
