Using the appropriate Ksp values, find the concentration of Cu2+ ions in the solution at equilibrium after 550 mL of 0.50 M aqueous Cu(NO3)2 solution has been mixed with 500 mL of 0.30 M aqueous KOH solution. (Enter in M.) (Ksp for Cu(OH)2 is 2.6x10-19).

Now find the concentration of OH− ions in this solution at equilibrium. (Enter in M.)

Answer #1

The KOH is limiting reagent in our case so the Conc of Cu2+ is the concentration of left moles after the reaction. the KOH is completely used in the reaction, therefore, there is no OH- cons. in reaction initially

At equilibrium, we may find with the help of Solubility product Ksp

so our OH- conc is

I hope this helps you please rate this answer :)
