Question

Write the chemical equation that describes how calcium carbonate neutralizes acid

Answer 1

Answer:

$CaCO_3+2HCl-->CaCl_2+CO_2+H_2O$

Explanation:

Hello,

Typically, calcium carbonate is suitable to neutralize specifically hydrochloric acid via the required chemical reaction which is shown below:

$CaCO_3+2HCl-->CaCl_2+CO_2+H_2O$

Carbon dioxide and water are yielded as carbonic acid is firstly yielded but it is unstable enough to be segregated into carbon dioxide and water. In addition, calcium chloride is yielded as an evidence of the acid's neutralization.

Best regards.

Answer 2

Answer;

CaCO3(s)+ 2 H+(aq)  → Ca+2 + CO2(g) + H2O(l)

Explanation;

• The reaction of an acid with calcium carbonate is an example of an acid-base reaction.
• In these reactions, an acid will react with a base to form a salt and water. The acid was neutralized by the base.

• For example, CaCo3 will neutralize HCl by the following equation:

2HCl(aq) +CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g)
