Question

Complete the following ionic equations in reference to electrolysis and electroplating

${\mathrm{OH}}^{-}-\mathrm{\_\_\_}\to \mathrm{\_\_\_\_\_}$

Answer 1

Electrode reaction

• The oxidation half-reaction occurring at the anode is given in this reaction
• Here, the hydroxyl ion losses an electron and forms hydroxyl atoms

${\mathrm{OH}}^{-}-\mathbf{}{\mathbf{e}}^{\mathbf{-}}\to \mathbf{OH}$
