In acidic medium, dichromatic ion oxidises ferrous ion to 'ferric ion. If the gram molecular weight of potassium dichromate is 294 g, its gram equivalent weight (in grams) is

Step-by-step solution

In acidic medium, K ₂ Cr ₂ O ₇ acts as strong oxidising agent and itself gets reduced to Cr ³⁺ . Equivalent weight of K ₂ Cr ₂ O ₇= Molecular weight 6 = 294 6 =49
