    Another important parameter that may affect a precipitate’s solubility is pH. For example, a hydroxide precipitates such as FeOH 3 is more soluble at lower pH levels where the concentration of OH – is small. Because fluoride is a weak base, the solubility of calcium fluoride, S CaF2, also is pH-dependent.We can derive an equation for S CaF2 by considering the following equilibrium reactions
