A water sample from a sunny southern California water treatment plant contains 2.80mg/L of iron(Fe^3+). The goal of the treatment facility is to lower the concentration of iron to 0.3 mg/L by precipitation. What hydroxide concentration is necessary to obtain this result? What would the pH be for that concentration?
