### n in Equation

I'm a bit confused as to how to find n in reactions and I'm a bit confused too with what it represents.

For example,
for the reaction Mn + Ti2+ <--> Mn2+ + Ti n=2, but I'm not sure as to why.

Could someone help explain?

### Re: n in Equation

n represents the moles of electrons transferred in a redox reaction. To know how many electrons are transferred, you have to divide a redox reaction into its reduction and oxidation half-reactions.

n is the number of electrons so you would divide the rxn into half rxns and see how many electrons are being transferred and thats your n. In this case it is 2.

### Re: n in Equation

When you look at the individual half reactions, n represents the moles of electrons being transferred. This value must be the same for both half reactions.

Look for the number of electrons being transferred between the half reactions

### Re: n in Equation

In the equation, n is the number of electrons in moles that is being transferred.

One thing to remember is that you should always take the balanced number of moles of electrons for the reaction as your value of n.
