5. For those mixtures that result in precipitate formation, identify the precipitate. For those mixtures that do not result in precipitate formation, explain why. Refer to a table of Kgp values as needed. a. 20.0 mL 0.020 M Ba(NO3)2 mixed with 80.0 mL of a pH 12 buffer. b. 60.0 mL 0.010 M CuSO4 mixed with 40.0 mL 0.010 M K2CO3. c. 40.0 mL 0.10 M MgCl2 mixed with 60.0 mL 0.10 M NaNO3.
