Calcium and magnesium react with water to form alkaline-earth hydroxides while at the same time issuing hydrogen. The aqueous solution of such hydroxides shows the typical properties of an alkaline solution. Calcium hydroxide solution also referred to as lime water is used for indicating the presence of carbon dioxide.
Prepare a solution of calcium hydroxide (alkaline solution of calcium) and a solution of magnesium hydroxide (alkaline solution of magnesium) and study their properties.
