Vedclass · Answer

(B) Incorrect: In the reaction between $KMnO_4$ and $C_2O_4^{2-}$,$C_2O_4^{2-}$ is oxidized to $CO_2$,so it acts as a reducing agent.$(b)$ Correct: $KMnO_4$ is a well-known strong oxidizing agent in acidic medium.$(c)$ Incorrect: The $Cr_2O_4^{2-}$ ion (chromate) has a tetrahedral geometry,where the bond angle is approximately $109.5^o$,not $120^o$.$(d)$ Incorrect: The standard reduction potential for the reaction $Cr_2O_7^{2-} + 14H^+ + 6e^- 	o 2Cr^{3+} + 7H_2O$ is $E^o = +1.33 \ V$,not $-1.33 \ V$.
