Question

Which of the following is amphoteric oxide? Mn2O7, CrO3, Cr2O3, CrO, V2O5, V2O4 (A) V2O5, Cr2O3 (B) Mn2O7, CrO3 (C) CrO, V2O5 (D) V2O5, V2O4

In chemistry, an amphoteric species is a molecule or ion which can react as an acid as well as a base. This word is derived from the Greek word amphotericin which is meant for "both": Many metals like zinc, tin, lead, aluminium, beryllium, etc formamphoteric oxides or hydroxides.

Here both

V_{2} O_{5}

and

C r_{2} O_{3}

can show the property of acidic as well as basic oxide both. Thus option

A

is correct.
