How does an acid react with carbonates?

Answer 1

When acids react with a carbonate or a hydrogencarbonate (or a metal carbonate or a metal hydrogencarbonate) carbon dioxide, water and a salt solution is produced. That is:

acid + metal --> carbon dioxide + water + salt solution

An example is the following ionic equation:

CH3COOH(aq) + NaHCO3(s) --> CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)

You can see this reaction occur when you mix vinegar with some bicarbonate soda (sodium hydrogencarbonate), which is the reaction they use in those little volcanoes you make in the school sand pit ahahaha lol this answer is from Jennifer and by the way She rules jk i suck

Answer 2

When an acid reacts with carbonates, it forms carbon dioxide gas, water, and a salt. The acid reacts with the carbonate ion (CO3 2-) to produce carbon dioxide gas, which bubbles out of the solution. The remaining components form a salt and water.

Answer 3

When acids react with carbonates, salt, water and carbon dioxide are produced.

An example would be

2HCl + CaCO3 -----> CaCl2 + H2O + CO2

The more general ionic equation is CO32- + 2H+ ------> CO2 + H2O

Answer 4

Yes, almost all acids will react with carbonate when they are at least stronger than Hydrogen carbonate acid (HCO3-) which is a very weak one (pKa=10.25).

Answer 5

CaCO3 + 2HCl --> CaCl2 + CO2 + H2O

Like this. Producing a salt, carbon dioxide gas and water.

Answer 6

a gas forms (carbon dioxide)
