Question

What forms when aluminum hydroxide neutralizes hydrochloric acid?

Answer 1

A chemical reaction involves the reacting of two species to form a new product with a different chemical composition. Neutralization reaction is one such type of a chemical reaction. This type of reaction occurs when an acid reacts with a base to produce a salt as a product.

Complete answer:
We have studied various types of reactions like, combination, decomposition, displacement, redox, etc. One of the reactions is a neutralization reaction. It is the reaction where an acid and a base reacts to neutralize each other and forms salt and water.
We have been given a metal hydroxide, which is basic in nature, that is aluminum hydroxide $Al{{(OH)}_{3}}$. The other reactant is an acid which is hydrochloric acid HCl, it is considered as a strong acid. The reaction between these two happens as a neutralization reaction in which a salt of the aluminum metal is formed as aluminum chloride$AlC{{l}_{3}}$along with water as one of the products.
The neutralization between aluminum hydroxide and hydrochloric acid is as follows:
$Al{{(OH)}_{3}}+HCl\to AlC{{l}_{3}}+3{{H}_{2}}O$
Hence, when aluminum hydroxide neutralizes hydrochloric acid a salt aluminum chloride and water are formed.

Note:
The neutralization is of 4 types, between strong acids and bases that produce neutral products. This is one such example. Others include strong acid and weak base that produce acidic products, a strong base and weak acid produce basic products, while both weak acids and bases don't undergo neutralization. An example of neutralization is the acidity in the stomach that produces HCl, which is neutralized by the intake of milk of magnesia (magnesium hydroxide).
