Alkali metals such as sodium are stored under

Options

A. kerosene oil
B. acetone
C. chloroform
D. alcohol

Answer

A

Explanation

All the alkali metals get tarnished on exposure to atmosphere (air and moisture ) as they are converted into oxides, hydroxides, and finally to carbonates. Thus, alkali metals are stored under inert hydrocarbon solvents like petroleum, ether, and kerosene oil which prevent them from coming in contact with air and moisture.
