Whst is vf for KMnO4 and Cu2S
1 and 2 I suppose ???
no it is 5 and 8
It should be 5
May I know what is valence factor and in which chapter it is in? @Akash_Mukherjee
And @Sarvesh_Pnchl it's the change in oxidation state for redox reactions, so you need to tell the medium for kmno4
n factor of kmno4 in acidic medium is 5 while in neutral it is 3 and in basic its n.f is 1.
What about Cu2S bro ?
Valency factor is basically n factor only....
Ohh didnt hear this valence factor name before..!
N factor is ok.
