Answer 1

The Alkaline earth metal present in the following materials like lime stone , slaked lime , quicklime and gypsum is Calcium and the Alkaline earth metal present in Epsom salt is Magnesium.

• Calcium is the 20th element and Magnesium is the 12th element in the periodic table.

Chemically, the given materials are represented in the following manner.

• Limestone is Calcium Carbonate - CaCo3
• Slaked Lime is Calcium Hydroxide - Ca(OH)2
• Quicklime is Calcium Oxide - CaO
• Gypsum is Calcium Sulfate Dihydrate - CaSO4.2H2O
• Epsom salt is Magnesium Sulfate - MgSO4

• Limestone on heating decomposes to Quicklime, and on hydrating the quicklime, Slaked lime is formed.

• Gypsum is an important ingredient in the manufacture of cement. The hydrate of gypsum is known as Plaster Of Paris.

• Epsom salt has some uses in plants.

Hence the Answer is Calcium and Magnesium.
