What happens when an acid reacts with a carbonate?

Answer 1

A salt, carbon dioxide and water is produced.

Eg. 2HCl + Na2CO3 -------> 2NaCl + CO2 + H2O

Reaction: hydrochloric acid + Sodium carbonate produce sodium chloride (salt), carbon dioxide and water.

Answer 2

We get salt, water and a gas. For example: 2 Hcl+CaCO3= Cacl2 + H2O + CO2

The air always contains a small amount of carbon dioxide. In recent years this has been increasing because of the fuels burn. When people talk about 'carbon footprint', they are referring things they do that add to carbon dioxide in the air.

Carbon dioxide reacts with rainwater to make very weak acid. Over years and years, this acid can damage buildings as well as living things growing in the earth's surface.

Some buildings are made out of limestone. These are easily damaged when the acid in rain reacts with the limestone.

Answer 3

An acid can be shown as an hydromium ion (H3O+)

and a carbonate can be shown as a (CO32-)

CO32- + H3O+ <=> HCO3- + H2O

HCO3- + H3O+ <=> H2CO3 + H2O

The H2CO3 exists as an equilibrium

H2CO3 <=> CO2 + H2O

Answer 4

When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!

Answer 5

when the acid touches the carbonate, it will create hydrogen gas, resulting in the solution to bubble/fizz.

Answer 6

The products of the reaction are a salt, carbon dioxide and water.

Answer 7

You get lots of CO2 (Carbon Dioxide).

Answer 8

salt and hydrogen gas is produced
