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++6e2K++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

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?
