Calculate the equivalent mass of hcl in the given reaction : k2cr2o7+14hcl--->2kcl + 2crcl3 + 3cl2 + h2O

In the given equation, HCl is oxidised to Cl2 Change in oxidation number = 0-(-1) = 1 n factor= 6 / 14 Molecular mass of HCl is = 36.5 Equivalent mass = (Molecular mass of HCl)/(n factor) = 36.5/(6/14) = 85.1 Hence 85.1 is the equivalent mass of HCl.
