Q.10.68 - An Introduction to General, Organic, and Biological Chemistry

Question

Write the balanced chemical equation for the neutralization reaction of stomach acid HCL with Al(OH)3, an ingredient in some antacids.

Step-by-Step Solution

Answer

$3\mathrm{HCl}\left(aq\right)+\mathrm{Al}\left(\mathrm{OH}{)}_3\right(s)\to {\mathrm{AlCl}}_3(aq)+3{\mathrm{H}}_2\mathrm{O}(l)$

Step 1: Given Information

The representation of a chemical reaction in the type of substance is known as a chemical equation. The equation in which the quantity of iotas of the relative multitude of atoms is equivalent on the two sides of the equation is known as a decent chemical equation.

Step 2: Explanation

We know,

HCL is a monobasic acid and $\mathrm{Al}\left({\mathrm{OH}}_3)\right.$is tribasic base.

One mole of $\mathrm{Al}\left({\mathrm{OH}}_3)\right.$will neutralize three moles of HCL.

Hence the balanced chemical equation is,

$3\mathrm{HCl}\left(aq\right)+\mathrm{Al}\left(\mathrm{OH}{)}_3\right(s)\to {\mathrm{AlCl}}_3(aq)+3{\mathrm{H}}_2\mathrm{O}(l)$
