Aluminum reacts with sodium hydroxide to form a salt called sodium aluminate (NaAlO2) and hydrogen gas. … In general, a metal reacts with an acid, forming salt and hydrogen gas.
What happens when aluminum hydroxide reacts with sodium hydroxide?
Aluminum reacts with sodium hydroxide and water to form sodium tetrahydroxoaluminate and hydrogen. … Aluminum is an amphoteric element, which means it reacts with acids and bases to form a salt and hydrogen. The reaction is strongly exothermic.
What happens when aluminum reacts with class 10 sodium hydroxide?
When aluminum reacts with sodium hydroxide, it gives aluminate salt and hydrogen gas. Metallic aluminum is amphoteric in nature and will react with both acid and low
What happens when aluminum oxide reacts with sodium hydroxide and also writes its chemical reaction?
The reaction between alumina/oxidized aluminum and sodium hydroxide produces sodium aluminate and water as a result or product of the reaction. … Here it reacts with sodium hydroxide to form sodium aluminate salt and water. The balanced reaction equation is: Al2O3 + 2NaOH(aq) > 2NaAlO2(aq) + H2O(
What happens when aluminum reacts with sodium hydroxide and also writes its chemical reaction?
Answer: Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminum, which is an amphoteric metal. The reaction is highly exothermic once initiated and is accompanied by rapid evolution of hydrogen gas. The reaction is sometimes written: 2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H
