which reducing agent is the stronger one
« on: January 10, 2010, 04:09:59 PM »
Will it be 1M I- or 2M I-?

i thought that 1M would be stronger but the answer key says that it's actualyl 2M?? what is the reason behind this

Calculate potential with Nernst equation.

Calculate potential with Nernst equation.

we didn't learn this "Nernst equation", is there another possible way to determine it?

Nernst equation is a way of calculating potential for a given concentrations. Basically it follows an obvious logic - the higher the concentration the "stronger" the reagent.
