Consider the titration of potassium dichromate solution with acidified

1.	Consider the titration of potassium dichromate solution with acidified Mohr's salt solutionusing diphenylamine as indicator. The number of moles of Mohr's salt required per mole of dichromate is :
Answer» 3 4 5 6 Solution :`Cr_(2)O_(7)^(2-)+6Fe^(2+) +14H^(+) to 2Cr^(3+) +6Fe^(3+)+7H_(2)O` 1 MOLE of dichromate oxidises SIX MOLES of ferrous ion present in Moh's salt
