Two equations can be written for the dissolution of Mg(OH) 2 (s) in acidic solution. (a) Explain

Question:

Two equations can be written for the dissolution of Mg(OH)₂(s) in acidic solution.

2+ Mg(OH)2(s) + 2 H* (aq) Mg+ (aq) + 2 HO(1) A.G -95.5 kJ mol- 1 Mg(OH)2(s) + H* (aq) 1 2 A,G = 2+ Mg+ (aq)

(a) Explain why these two equations have different Δ_rG° values.

(b) Will K for these two equations be the same or different? Explain.
