Which of the following is amphoteric oxide ?

1.	\(V_{2} O_{5} , C r_{2} O_{3}\)	2.	\(M n_{2} O_{7} , C r O_{3}\)
3.	\(C r O , V_{2} O_{5}\)	4.	\(V_{2} O_{5} , V_{2} O_{4}\)

NEETprep Answer:

V_{2} O_{5} a n d C r_{2} O_{3}

are amphoteric oxide because both react with alkalies as well as acids.

Note In lower oxides, the basic characteris predominant while in higher oxides, the acidic character is predominant.
