Which out of the following and why can be used to store an alkali metal ?
`H_2O, C_2H_5OH`, Benzene

Text Solution

Verified by Experts

Benzene can be used to store an alkali metal because other substances react with alkali metals as :
`Na+ H_2O to NaOH + 1/2 H_2`
` Na + C_2H_5OH to C_2H_5 Ona + (1)/(2) H_2`
