The bases found in the given substances are (1) Ca(OH)2 (2) NaOH (3) Mg(OH)2.
Lime water is an aqueous solution of calcium hydroxide dissolved in water. Similarly, the base used to form soaps is sodium hydroxide, mainly for the formation of sodium ion based soaps. Other types of ions can be used in place of Na to achieve varying results. Finally, the base found in milk of magnesia is magnesium hydroxide. This is a common laxative and digestive aid.
