Question

What is the equivalent mass of kmno4 in 2kmno4+16hcl=2kcl+2mncl2+8h2o+5cl2?

Answer 1

Well, you have done the hard part....

Explanation:

`KMnO_4(aq) + 8HCl(aq)rarr MnCl_2(aq) + KCl(aq) + 4H_2O(l) + 5/2Cl_2(g)uarr`

...the which equation is BALANCED with respect to MASS and charge...as indeed it must be if we purport to represent an actual chemical process.

And the oxidant is permanganate...the which is reduced to `Mn^(2+)`....

`MnO_4^(-) +8H^+ +5e^(-) rarr Mn^(2+) + 4H_2O(l)`

Potassium permanganate has a molar mass of `158.03*g *mol^-1`, and reacts with five moles of electrons, so its equivalent weight is....`31.6*g*mol^-1`
