What type of reaction is Al + NaOH? What are the products formed?

By Ritesh|Updated : November 9th, 2022

Al + NaOH is a displacement reaction where sodium is displaced by aluminum. The products formed is a salt and hydrogen gas. One element is replaced by another in a compound in a single displacement reaction, which is also known as a single replacement reaction. This type of chemical reaction is an oxidation-reduction reaction.

Displacement reaction

Displacement reactions are those in which a more reactive element removes a less reactive element from its compounds.

When one element in a compound replaces another, it causes a single displacement reaction. A metal can only replace another metal, and a nonmetal can only replace another nonmetal. The other element cannot be replaced except by a more reactive component of the chemical with which it reacts.

The reaction of Aluminum with Sodium hydroxide:

The reaction of Aluminum with Sodium hydroxide (Al + NaOH) produces a salt and Hydrogen gas.

2Al (s) + 2NaOH (l) + 6H2O (l) → 2Na[Al(OH)4](s) + 3H2(l)

This reaction is a displacement reaction because Aluminum removes Sodium from its compound.

Summary:

What type of reaction is Al + NaOH? What are the products formed?

Al + NaOH is a displacement reaction where sodium is displaced by aluminum. Salt and hydrogen gas are the end results of the process. A single displacement reaction, often referred to as a single replacement reaction, replaces one element in a compound with another. An oxidation-reduction reaction is the sort of chemical process in question.
