Question

From the given compounds, $X$ is the number of compounds which are acidic in water.

$C a O, {S O}_{2}, {S O}_{3}, {F e}_{2} O_{3}, {C l}_{2} O_{7}, {C O}_{2}, {N a}_{2} O$ .

Find the value of $X$ .

Solution

Generally, metallic oxides are basic in nature and non-metallic oxides are acidic in nature.

Value of $x = 4$
$S O_{2}, S O_{3}, C l_{2} O_{7}, C O_{2}$ are acidic in nature.

$C a O, {N a}_{2} O$ are basic in nature.

${F e}_{2} O_{3}$ is amphoteric in nature.
