Sodium form a crystallic ionic solid with dihdrogen . The solid is non-volatile and non-conducting in nature .It reacts violently with water to produce dihydrogen. The solid is non-volatile and non-conducting in nature. It reacts violenty with water to produce dihydrogen gas. Write the formula of this compound and its reaction with water. What will happen on electrolysis of the melt of this solid ?

Answer

N/a

Explanation

Sodium reacts dihydrogen to from sodium hydride which is a crystalline ionic solid.
`2Na + H_(2) to 2Na^(+)H^(-)`
It reacts violenty with water to produce `H_(2)` gas
`2NaH + 2H_(2)O to 2NaOH + 2H_(2)`
In solid state, NaH does not conduct electricity. On electrolysis, in its molten state it given `H_(2)` at anode and Na at cathode
`Na^(+)H^(-)(l) overset("Electrolysis") to underset("At cathode") (2Na(l)) + underset("At anode")(H_(2) (g))`
