Question

22. What happens when an acid reacts with a base ? Explain by taking the example of hydrochloric acid a
sodium hydroxide. Give equation of the chemical reaction which takes place. What is the special name
such a reaction ?
with metal oxide ? Explain with the help of an example. ​

Answer 1

Answer:

When acid reacts with a base salt and water are formed.

Example,

HCl+NaOH-> NaCl+H2O

Here Sodium Chloride and water are the products.

We know that metal oxides are basic in nature. Hence they react with acids  to form salt and water.

Here, NaOH is one such example of metal oxide. Here it acts as a base.

Such reactions are called neutralisation reactions.

K2O+H2SO4-> K2SO4+H2O.

Again, here K2O is the metal oxide.

Answer 2

When hydrochloric acid reacts with sodium hydroxide solution, then a neutralisation reaction takes place to form sodium chloride and water. NaOH(aq) + HCl(aq) →NaCl(aq) + H2O(l) Such reaction is called Neutralisation reaction.
