Question

Aluminium + sodium hydroxide + water gives sodium meta aluminate + hydrogen

Answer 1

Explanation:

Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. The reaction is highly exothermic once established and is accompanied by the rapid evolution of hydrogen gas. The reaction is sometimes written as: 2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H.

Answer 2

Answer:

$2Al + 2NaOH + 2H_{2}O→2NaAlO_{2} + 3H_{2}.$
