Calcium carbonate is an alkali salt. Alkali salts are bases, and are formed from the neutralization reaction between a strong base and a weak acid. For example:

Ca(OH)2 + H2CO3 --> CaCO3 + H2O

strong base + weak acid ---> alkali salt + water

Is calcium carbonate carbonic acid?

No, calcium carbonate (CaCO3) is the calcium salt of carbonic acid (H2CO3). If a compound has the name of a metal in it (sodium, calcium, copper, etc) it is generally not an acid but a salt. A salt is formed when a metal ion or other positive ion takes the place of hydrogen in an acid.


Is calcium carbonate an acid or a base or a salt?

Calcium carbonate, like other carbonates, is alkaline.


Why does calcium carbonate appears to get lighter when it reacts with acid?

Reacting with an acid calcium carbonate is transformed in another salt.


What does calcium carbonate and acid make?

The calcium salt of the acid used and carbon dioxide.


What is the name of the salt that is formed by nitric acid and calcium carbonate?

The salt formed by nitric acid and calcium carbonate is calcium nitrate. It is created when nitric acid reacts with calcium carbonate, which is a common chemical reaction used in various industries.


What is the pH range of the resulting product from carbon dioxide and limewater?

Calcium hydroxide in limewater reacts with carbon dioxide to form calcium carbonate (insoluble and hence the emergence of murkiness) and water. Calcium carbonate can be considered as the salt formed from the neutralization of a strong base, calcium hydroxide, and a weak acid, carbonic acid. The pH of the solution of such a salt will be basic because the conjugate base of the weak acid, carbonate, is weakly basic.


Can calcium carbonate neutralize an acid?

Yes. Calcium carbonate can neutralize acids, producing carbon dioxide and a calcium salt that corresponds to the acid.


Is calcium carbonate a buffer?

Calcium carbonate is not considered a buffer because it is a weak base that can neutralize acids, but it lacks the ability to maintain a stable pH in a solution. Buffers are composed of a weak acid and its conjugate base or a weak base and its conjugate acid, which work together to resist changes in pH.


Is calcium phosphate an acid base salt or neutral?

Calcium phosphate is a neutral salt since it is formed from the reaction between a base (phosphate) and an acid (calcium). It does not have the characteristics of an acid or a base.


Is Calcium perchlorate acid or base?

Calcium perchlorate is a salt, not an acid or a base. It is composed of calcium cations (Ca2+) and perchlorate anions (ClO4-).


Which salt is formed when acetic acid react with calcium carbonate?

Calcium acetate is formed when acetic acid reacts with calcium carbonate. This reaction produces calcium acetate, water, and carbon dioxide.


Is silver carbonate an acid or base?

Silver carbonate is a CHEMICAL SALT. Hence it is neither an acid nor a base.
