Webreduction reaction will depend on pH if the ORP of the oxidant or reductant is pH dependent. The following titration curve (see Graph 2) shows the ORP of the reaction of hypochlorous acid and bisulfite ion. The half-reactions for both of the redox couples are pH dependent. The titration curves for each pH are offset, but retain the same basic form. WebA pH curve is a graph produced from a titration that shows how the pH of a solution changes when we add an acid or alkali to it. The equivalence point of a titration is when a …

WebOct 15, 2024 · When the pH value is a whole number (e.g. pH 7), the number is equal to the negative exponent of the H + ion concentration. (8.2) pH value = X [ H +] = 10 − X M. So for pH 7, the H + ion concentration is 10 -7 M. The pH values of everyday chemicals typically range from pH 0 to pH 14. WebTo measure the pH accurately, you can use a pH meter which has a probe which you simply put into your solution and get a digital read-out of the pH. Ideally, the pH meter is adjusted before use by putting the probe into a solution of accurately known pH - for example, pH 4.0 or pH 10.0. The meter is then adjusted so that it reads exactly 4.0 or ...
