Question

Using the appropriate K_sp values, find the concentration of K⁺ ions in the solution at equilibrium after 700 mL of 0.30 M aqueous Cu(NO₃)₂ solution has been mixed with 500 mL of 0.25 M aqueous KOH solution. (Enter in M.) (K_sp for Cu(OH)₂ is 2.6x10^-19).

I got 0.104 for the K+ concentration but cannot get the OH- concentration

Expert Solution

Step 1

The reaction taking place is

Cu(NO₃)₂ (aq) + 2 KOH (aq) ----> Cu(OH)₂ (s) + 2 KNO₃ (aq)

Since in the above reaction, the salt of K is completely soluble

Hence the moles of K⁺ ion = moles of KOH taken
