Sodium fire in the laboratory should not be extinguished by using water. Why ?

Text Solution

Verified by Experts

Sodium reacts violently with water
`Na+H_(2)O rarr NaOH+H_(2)uarr`
thus producing sodium hydroxide and hydrogen gas. As `H_(2)` gas is inflammable, it catches fire. As a result, the fire spreads. Therefore, water should not be used to extinguish the fire caused by sodium (insted `C CI_(4)` should be used).
