Problem- suppose you place 1.0 g of Cu(IO3)2 in contact with 50 mL of distilled water and gently stir. Show graphically how the concentrations of Cu2+ and IO3- in solution will change with time, assuming that solid and liquid are placed in contact at t=0. The plot should be qualitative.
How do I yet start setting this up? Thank you
