Question:

The electrolysis of MgCl₂(aq) can be represented as

Mg+ (aq) + 2Cl(aq) + 2 HO(1) Mg2+ (aq) + 2OH(aq) + H(g) + Cl(g)

The electrolysis of a 315 mL sample of 0.185 M MgCl₂is continued until 0.652 L H₂(g) at 22 °C and 752 mmHg has been collected. Will Mg(OH)₂(s) precipitate when electrolysis is carried to this point? Notice that [Mg²⁺] remains constant throughout the electrolysis, but [OH¯] increases.
