What is the oxidation state of chromium in the final product formed by the reaction between $KI$ and acidic $K_2Cr_2O_7$ solution?

How many moles of $KMnO_4$ will be reduced by $1$ mole of $KI$ in an alkaline medium?

Identify the reaction in which monobasic and dibasic acids are formed.

The acidic solution of $S_2O_3^{2-}$ is converted to ....... in the presence of $I_2$.

How many moles of $KMnO_4$ are required to oxidize $1 \ mol$ of $Fe(C_2O_4)$ in an acidic medium?

$MnO_4^{-}$ oxidises $(i)$ oxalate ion in acidic medium at $333 \ K$ and $(ii)$ $HCl$. For balanced chemical equations,the ratios $[MnO_4^{-} : C_2O_4^{2-}]$ in $(i)$ and $[MnO_4^{-} : HCl]$ in $(ii)$ respectively are
