1.	An element A in a compound ABD has oxidation number An-. It is oxidised by Cr2O−72 in acid medium. In the experiment 1.68×10−3 x moles ofK2Cr2O7 were used for 3.26×10−3 moles of ABD. The new oxidation number of A after oxidation is:
Answer» An element A in a compound ABD has oxidation number A^n-. It is oxidised by $C r_{2} O_{7}^{-} 2$ in acid medium. In the experiment 1.68 $\times$ $10^{-} 3$ x moles of $K_{2} C r_{2} O_{7}$ were used for 3.26 $\times$ $10^{-} 3$ moles of ABD. The new oxidation number of A after oxidation is:
