To predict the calcium compound among the following that does not dissolve in hydrochloric acid. Concept introduction: Calcium is one of the most abundant elements found on earth. It is an alkaline earth metal and belongs to group 2A of the periodic table. Its compounds have high melting point. Calcium occurs in various minerals that are found on earth’s surface. Some common minerals are limestone, dolomite, slaked lime, gypsum and chalk. Calcium Oxide is quick lime and is a white, amorphous solid. Calcium hydroxide is known as slaked lime. Both are slightly soluble in water and dissolve in acids. Calcium carbonate is present in limestone and chalk. The hydrated calcium sulfate is known as gypsum. Cement also contains calcium. Hydroxyapatite is also a type of calcium compound found in tooth enamel.
