WebJul 26, 2024 · The effect of pH on the degradation of MC by a photocatalytic process under visible light was analyzed in the range of pH 2–pH 10 using 0.4 g L −1 Ag/AgCl-G. Figure 4a shows that degradation was highly effective at higher pH values especially at pH 10. WebA reference electrode is an electrode which has a stable and well-known electrode potential. The overall chemical reaction taking pace in a cell is made up of two independent half-reactions, which describe chemical changes at the two electrodes. To focus on the reaction at the working electrode, the reference electrode is standarized with ...
WebSubstituting equation (1) into (2) we get, E cell = E cal – E Gless – 0.0591 pH. pH = (Ecal – EGless – Ecell) / 0.0591. Thus the pH of an unknown solution can be easily determined by measuring the e.m.f. of the cell, since, E Cal and E 0Glass are known. Glass electrodes are commercially available. WebNote that the effluent will now be very alkaline: pH = 14 + log .04 = 12.6, so in order to meet environmental standards an equivalent quantity of strong acid must be added to neutralize the water before it is released.
