Question: The selectivity coefficient,K pot Li ,H+, for a L i+ ion-selective electrode is 4 10 -4 . When this electrode is placed in 3.44

The selectivity coefficient,K^pot_Li,H+, for a Lⁱ⁺ ion-selective electrode is 4 × 10^-4. When this electrode is placed in 3.44 × 10^-4 M Li solution at pH 7.2, the potential is - 0.333 V versus S.C.E. What would be the potential if the pH were lowered to 1.1 and the ionic strength were kept constant?
