When sodium hydroxide solution is added to copper(II) sulfate solution, a blue precipitate is formed.
The balanced equation for this reaction is:
CuSO4(aq)+2NaOH(aq)→Cu(OH)2(s)+Na2SO4(aq) \text{CuSO}_4(\text{aq}) + 2\text{NaOH}(\text{aq}) \rightarrow \text{Cu(OH)}_2(\text{s}) + \text{Na}_2\text{SO}_4(\text{aq}) CuSO4(aq)+2NaOH(aq)→Cu(OH)2(s)+Na2SO4(aq)Write the ionic equation, including state symbols, for this reaction.
