9Ec Metal Carbonates and Acids

In general metal react with acids to give , r and di.

The word tells us that the chemical contains carbon and . It is the -ate part that tells us that it contains .

For example when green crystals are added to sulphuric acid a of is produced. gas is released and also .

We can test for by bubbling the gas through which will turn .

If all the sulphuric acid is used up in the reaction then the pH of the solution will become .

If we touch the reaction flask where the reaction is taking place we will detect a in temperature.

Calcium carbonate reacts with sulphuric acid to give carbon dioxide, water and .

Calcium reacts with hydrochloric acid to give carbon dioxide, water and calcium .

Calcium carbonate reacts with to give carbon dioxide, water and calcium nitrate.

stone, and c contain calcium carbonate.

So the general rule for reaction between metal carbonate and acid is :-

metal + acid --> dioxide + + salt
