What is the primary difference between the endpoint and equivalence point in titrations?

Using the Nernst equation, determine the potential range for an indicator with a transition ratio from 0.1 to 10, given n = 1.

Given a redox reaction with a standard cell potential of 0.60 V, 3 electrons transferred, and a ratio of reduced to oxidized indicator of 10, calculate the cell potential using the Nernst equation.
