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=
| 294.2 |
| 6 |
=49

molecular weight of pottasium dichromate = 294 , X factor in acidic medium = 6
equivalent weight = molecular weight / X factor
= 294 / 6 = 49

Dear ANIL PANDEY,
Molecular weight of pottasium dichromate(K2Cr2O7) = 294 g
X factor in acidic medium = 6
Equivalent weight = molecular weight / X factor
= 294 / 6
= = 49 g
This is your answer ..

Mol. Wt of potassium dichromate is 294.19 and the valency (X factor) is 6 . So it should be 294.19÷6= 49.03

Equivalent weight = molecular weight/basicity or acidity. How did u know that the basicity of potassium dichromate is 6?
