Question

what happen when an acid reacts with a metal oxide? Explain with the help of an example. write write a balanced equation for the reaction involved.

Answer 1

When an acid reacts with a metal oxide it forms hydrogen gas and salt.

E.g. H2SO4 + Zn --------> ZnSO4 + H2

From this example you can see that H2 is released and ZnSO4 in the form of salt is produced

Answer 2

Answer: It leads to the production of salt and water.

Explanation:

When an acid reacts with a metal oxide, it leads to the production of salt and water molecule. The equation involving this type of reaction follows:

$Acid+\text{Metal oxide}\rightarrow Salt +H_2O$

For Example: Reaction of zinc oxide and an acid known as hydrochloric acid, the equation follows:

$ZnO+2HCl\rightarrow ZnCl_2+H_2O$

By Stoichiometry of the reaction:

1 mole of zinc oxide reacts with 2 moles of hydrochloric acid to produce 1 mole of zinc chloride and water molecule.

Hence, it leads to the production of salt and water.
