1 Volt?

    How far do you need to separate two opposite 1C charges inorder for the potential difference to be 1v?

    It's completely arbitrary as the potential would vary with distance from the charges. When you say potential difference though, what is your reference potential then? Is it assuming 0 V at infinity? If so then the potential that results from a point charge is trivial:
