Davy made a paste of slaked lime (which is calcium oxide slightly moistened, resulting to form calcium hydroxide) and red oxide of mercury (mercury oxide). He placed approximately 3.5 grams of mercury metal to act as an electrode.
Calcium hydroxide is used as a flocculant in water and sewage treatment. It is also used in fresh water treatment to raise the pH of the water thereby controlling the corrosion of pipes. It is widely used in the production of calcium stearate. It is an active ingredient in
