Chemistry - PERIODIC TABLE Question with Solution | TestHub

An oxide that combines with water to give an acid is termed as an acidic oxide. The oxide that gives a base in water is known as a basic oxide. An amphoteric solution is a substance that can chemically react as either acid or base.

${\mathrm{B}}_2{\mathrm{O}}_3$ and ${\mathrm{SiO}}_2$ both are oxides of non-metal and hence are acidic in nature.

$\left\{\begin{array}{l}\mathrm{CaO},\mathrm{BaO}=\mathrm{Basic} \mathrm{Nature}\\ {\mathrm{B}}_2{\mathrm{O}}_3,{\mathrm{SiO}}_2=\mathrm{Acidic} \mathrm{Nature}\\ {\mathrm{N}}_2\mathrm{O}=\mathrm{Neutral} \mathrm{oxide}\end{array}\right.$
