Question

metal oxide +acid gives metal salt + water
can u give an example ​

Answer 1

Answer:

CuO+2HCl-----> CuCl2 +H2O

Answer 2

Answer

$\sf Na_2O + H_2SO_4 \rightarrow Na_2SO_4 + H_2O$

$\rule{50}2$

Explanation

$\sf Na_2O$ (Sodium oxide) is a metal oxide which when reacted with an acid (here, sulphuric acid) gives metal salt (here, sodium sulphate) and water.

$\rule{100}{2}$

Other Information

→Metal reacts with oxygen to form Metal Oxides.

→Metal Oxide when added to water forms Metal Hydroxide

Ex $\sf MgO + H_2O \rightarrow Mg(OH)_2$

→Metal oxides and hydroxides are basic in nature.

→Bases which are soluble in water are called as alkaline.
