Identify the basic oxide from the following :

Identify the basic oxide from the following :
  1. $\mathrm{Cr}_2 \mathrm{O}_3$
  2. $\mathrm{CrO}_3$
  3. $\mathrm{V}_2 \mathrm{O}_5$
  4. $\mathrm{V}_2 \mathrm{O}_3$

Solution

The oxides of transition metal that contain metals in lower oxidation state are considered to be basic and basic character of metal oxide decreases along the period.
$\mathrm{V}_2 \mathrm{O}_3$ present in its lowest oxidation state The vanadium tends to donate the pair of electrons Hence it is basic oxide.
