I mixed 4.0mL of 0.10M Cu(NO3)2 and 2.0mL of 0.10M NaOH in a test tube, which was centrifuged afterwards until the precipitate settles. The supernate was then discarded, such that the precipitate was left alone inside the test tube. 6.0mL dH2O and 1.0mL NaOH was then added to the soln. How can I compute for the equilibrium constant upon addition of:
-4.0mL water
-3.0mL 6.0M H2C2O4
-water + Zn
-1.0mL 5.0M HNO3
-1.0mL 5.0M NH3

I need some serious help. :l
