In the standardization of Na_(2)S_(2)O_(3) using K_(2)Cr_(2)O_(7) by iodometry, the equivalent weight of K_(2)Cr_(2)O_(7) is

Answer»

(MOLECULAR weight)/2
(molecular weight)/6
(molecular weight)/3
Same as molecular weight

Solution :HYPO solution are USED as the reducing agent with POTASSIUM dicromate solution.
`K_(2)OVERSET(+6)(Cr_(2))O_(7)=("molecular weight")/(6)`
