Question

what happens when a acid reacts with metal hydrogen carbonate? write equation of the reactions which take place​

Answer 1

Answer :-

When metal hydrogen carbonates react with acids , The products obtained are their respective salt ,water and Carbon dioxide gas.

Equation type :-

Metal Hydrogen carbonate + Acid —> Salt + Water + Carbon dioxide

Here ,

Carbon dioxide is the gas evolved.

We can test it by passing the gas in lime water , its turns milky white which indicates that the resulted has is Carbon dioxide.

Example :-

Na2CO3 + HCl —> NaCl + H2O+CO2

Sodium hydrogen carbonate + Hydrochloric acid —> Sodium chloride + Water + Carbon dioxide.

==========

Hydrogen Carbonates /bi carbonates mean the same .

When , Metal carbonated react with acids also , the product is same i.e salt + water + Carbon dioxide.

•••

•Metal oxides are basic in nature

•Non metallic oxides are acidic in nature

••

•To know whether the substance is acidic or basic,we use litmus paper or pH scale (strength of acid /base).

Answer 2

Answer:

Salt , Carbon dioxide gas and water are formed when a acid reacts with metal hydrogen carbonate .

The equations of the reactions which take place are:

1)The reaction of carbonate with acid produces carbonic acid .

2) Carbonic acid decomposes rapidly into carbon dioxide and water .

3)Sodium hydrogen carbonate ( Na2Hco3 ) reacts with Hydrochloric acid ( HCI ) to produce sodium chloride , water and carbon dioxide .
