Question

Complete the following word equation and write balanced molecular equations for the same : $\mathrm{Copper}\left(\mathrm{II}\right)\mathrm{sulphate}+\mathrm{Sodium}\mathrm{hydroxide}\to$

Answer 1

Word Equation :

• $\mathrm{Copper}\left(\mathrm{II}\right)\mathrm{sulphate}+\mathrm{Sodium}\mathrm{hydroxide}\to \mathrm{Sodium}\mathrm{sulphate}+\mathrm{Copper}\mathrm{hydroxide}$.

Molecular Equation :

• ${\mathrm{CuSO}}_4\left(\mathrm{s}\right)+2\mathrm{NaOH}\left(\mathrm{s}\right)\to {\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{s}\right)+\mathrm{Cu}{\left[\mathrm{OH}\right]}_2\left(\mathrm{s}\right)\downarrow \left[\mathrm{pale}\mathrm{blue}\mathrm{ppt}.\right]$
