Question

Is anyone good at solubility equilibrium stuff? Could really use some help

Answer 1

At 25°C, a saturated solution of cerium(III) hydroxide (Ce(OH)3) contains 5.1 x 10–6 moles of the compound in one liter of solution.

What is the reaction equation?

Ce(OH)3(s) <-> Ce3+ (aq) + 3OH-(aq)

Ce(OH)3(s) <-> Ce3+ (aq) + OH-(aq)

3Ce3+(aq) + OH-(aq) <-> Ce(OH)3(s)

Ce(OH)3(s) <-> Ce3+ (aq) + (OH-)3(aq)
