Vedclass · Answer

(B) $Mn^{+3}$ is a strong oxidising agent because $Mn^{+2}$ is stable due to $d^5$ configuration. $Co^{+3}$ is also a strong oxidising agent in aqueous solution. This statement is correct.$(b)$ $Ti^{+2}$ $(d^2)$,$V^{+2}$ $(d^3)$,and $Cr^{+2}$ $(d^4)$ are strong reducing agents because they tend to lose electrons to achieve stable configurations. This statement is correct.$(c)$ $CrO_3$ is an acidic oxide because it reacts with water to form chromic acid $(H_2CrO_4)$. This statement is correct.$(d)$ For $Fe$,$E^{\circ}_{Fe^{+3}/Fe^{+2}} = +0.77 \ V$. Since the value is positive,this statement is incorrect.Therefore,only $1$ statement is incorrect.

How many statements are incorrect?
$(a)$ $Mn^{+3}$ and $Co^{+3}$ are strong oxidising agents.
