What is the eqevalent mass of k2cr2o7 in basic medium?

The equivalent mass of potassium dichromate (K₂Cr₂O₇) in basic medium is calculated based on its oxidation states and the number of electrons involved in the redox reaction. In basic conditions, K₂Cr₂O₇ typically reduces Cr(VI) to Cr(III), which involves a change of 6 electrons per formula unit. Therefore, the equivalent mass is the molar mass (approximately 294.19 g/mol) divided by 6, yielding an equivalent mass of approximately 49.03 g/equiv.
