The oxidation state of final product formed by the reaction between Kl and acidifed potassium dichromate solution is :

Answer»

`+4`
`+6`
`+2`
`+3`

Solution :`Cr_(2)O_(7)^(2-) + 14H^(+) + 6I^(-) to 2Cr^(3+) + 3I_(2) + 7H_(2)O`
oxidation of Cr is + 3 in the final product.
`underset("Calomel")Hg_(2)Cl_(2) + 2NH_(3) to Hg + Hg(NH_(2)) Cl + NH_(4)Cl`
