Question

Explain the following by giving examples.
1.) how metal oxides react with acid?
2.) how non metal reacts with base?

Answer 1

1.Metallic oxides react with acids to give salts and water. Here metal displaces hydrogen in acid and forms a salt. Displaced hydrogen adds with oxygen in metal oxide to form water. This is similar to neutralisation reaction so metallic oxides are basic in nature.

2.Acids are non-metals. They react with bases to form salts and water. Reactions of other non-metals with bases are actually quite complex. Non-metal oxides are usually acidic in nature and react with bases in the same way as acids (salt and water).

1)---METAL OXIDE +ACID ---->SALT + WATER

Na2O +HCl ----> NaCl + H2O.

2)-NON METALS + BASE ---> SALT +BASE.

CO2 + 2NaOH --->Na3CO3 +H2O
