The volume of HI(aq) required to reach the equivalence point : (1c) The pH at the half-neutralization point. (1d)The pH at the equivalence point.
Write three orbital designations that would be incorrect and explain why each is incorrect. For example, 1p would be an incorrect orbital designation because there is no p sub-shell in the first orbit.
