Problem:
A truck load full of the salt of barium hydroxide (Ksp = 5e-3) spills into a road-side lake. The lake is referred to by the local community as "Limestone Lake". Considering the equilibrium relationships for barium hydroxide's dissociation, limestone rock's dissociation, and those for carbonate chemistry, estimates the pH of this lake following the spill.
Hint: Your solution will require solving 6 separate expressions describing the equilibrium chemistry ongoing in this lake.
Note: Explain in detail.
