Chapter 4, Problem 23QP

Which of the following processes will likely result in a precipitation reaction? (a) Mixing an ${\text{NaNO}}_{\text{3}}$ solution with a ${\text{CuSO}}_{\text{4}}$ solution, (b) Mixing a ${\text{BaCl}}_{\text{2}}$ solution with a ${\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}$ solution. Write a net ionic equation for the precipitation reaction.
