HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤
K2Cr2O7 :- Potassium dichromate
Potassium dichromate in acidic medium is a strong oxidizer. It means it gains electrons during redox reaction. Potassium dichromate in acidic solution results in :
K2Cr2O7+14H++6e−→2K++2Cr3++7H2O
Equivalent weight ofK2Cr2O7=
294.26/6
=49
This could have been the simplest answer.
HOPE IT HELPS U.✌✌

weight of one K atom= 40 gms .K has oxidation state +1. weight of one Cr atom=48 gms. Cr has oxidation state of +6. weight of one O atom=16 gms . O has oxidation state of+2. Upon reduction Cr changes its oxidation state from +6 to +3.So there is 6 change in oxidation state per molecule of K2Cr2O7 and hence n factor is 6. total mass of K2Cr2O7=80+96+112=288. Equivalent weight of potassium dichromate =
288/6=48 gms .
288/6=48 gms .
