In disproportionation reaction, one element of a compound will simultaneously get reduced and oxidised. In ClO₄ -, oxidation number of Cl is +7 and it can not increase it further. So, ClO₄- will not get oxidised and so will not undergo disporportionation reaction.

Normality $= \frac{Volume strength}{5.6} = \frac{16.8}{5.6} = 3$ $\frac{}{} \frac{}{}$

Molarity $= \frac{Normality}{n - factor} = \frac{3}{2} = 1.5$

MnO? + H? C? O?2H? O - (H? )-> Mn²? + CO?
nf = (5) nf = (2)
Milli equivalent of C? O? ²? = mili equivalent of MnO?
2 x M x 10 = 5 x 0.05 x 10
M = 0.125 M
M = Strength / M.M of H? C? O?2H? O
Strength = 0.125 x 126g/L
= 15.75g/L

2MnO^-4 + bC2O^2-4 + cH⁺ xMn²⁺ + yCO2 + zH2O

If the above equation is balanced with integer coefficients, the value of c is_________.

The balanced equation is:
2MnO? + 5C? O? ²? + 16H? → 2Mn²? + 10CO? + 8H? O
So, the value of c (coefficient for H? ) = 16.
