WebSelective Precipitation Using pH. Many dissolved metal ions can be separated by the selective precipitation of the cations from solution under … Potassium chloride (KCl) acts as a source of chloride ions for the electrode. The advantage of using KCl for this purpose is that it is pH-neutral. Typically, KCl solutions of concentrations ranging from 3 molar to saturated are used in pH meters. See more However, pH is the measure of H+ activity, which is influenced by ionic strength. Adding KCl to the buffer raises its ionic strength, which should be reflected in … See more KCl is a neutral salt as it is made from the neutralization reaction of the strong acid(HCl) with a strong base(KOH). The pH value of the aqueous solution of KCl is 7 … See more Complete answer: -The ions from $KCl$ derived from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution so, … See more pH measurements are determined in both water and a calcium chloride solution because the calcium displaces some of the exchangeable aluminum.
