Calcium hydroxide can be used to neutralize the water in lakes that have been "killed" by acid rain. Ecologists hope that the original plants and animals will become re-established. • If the concentration of sulfuric acid in an acid lake is 1.2 x 10³ mol/L, and 1000 kg of calcium hydroxide is added to the lake, what is the volume of water in the lake that can be neutralized? • What is the original pH of the lake? What might be disadvantage(s) of using this method to neutralize the lake.
