Question

The incorrect statement among the following is :- (A) VOSO 4 is a reducing agent (B) Cr 2 O 3 is an amphoteric oxide (C) RuO 4 is an oxidizing agent (D) Red colour of ruby is due to the presence of Co 3+

Tardigrade Admin · Accepted Answer

(i) In VOSO 4, prime V prime is in +4 oxidation state. So it act as oxidising agent. (ii) Cr 2 O 3 is an amphoteric oxide. (iii) In RuO 4, 'Ru' is in +8 oxidation state. So it act as oxidising agent. (iv) Red colour of ruby is due to the presence of Cr +3 ions in Al 2 O 3.

Q. The incorrect statement among the following is :-

$V OS O_{4}$ is a reducing agent

$C r_{2} O_{3}$ is an amphoteric oxide

$R u O_{4}$ is an oxidizing agent

Red colour of ruby is due to the presence of $C o^{3 +}$

Q. The incorrect statement among the following is :-

VOSO4​ is a reducing agent

Cr2​O3​ is an amphoteric oxide

RuO4​ is an oxidizing agent

Red colour of ruby is due to the presence of Co3+

(i) In VOSO4​,′V′ is in +4 oxidation state. So it act as oxidising agent. (ii) Cr2​O3​ is an amphoteric oxide. (iii) In RuO4​, 'Ru' is in +8 oxidation state. So it act as oxidising agent. (iv) Red colour of ruby is due to the presence of Cr+3 ions in Al2​O3​.

$V OS O_{4}$ is a reducing agent

$C r_{2} O_{3}$ is an amphoteric oxide

$R u O_{4}$ is an oxidizing agent
