“…At the equivalence point, Ch = ca 'C cha, and Equation 23 is obtained. Ideally, the indicator chca/cha = kA = KAyHA/ynyA (21) ChCi/chi = ki = Kiyni/ynyi (22) should be selected so that the end-point color, or chi/ci, remains Vi log kA + Vz log Cha = log ki A serious problem exists only when log kx or log ki may be large relative to log cha, and this term can therefore be neglected. Thus Equation 24 is obtained.…”
