It is generally neutral, so it will take the pH of the solvent it is dissolved in. If your pH level is too high, one way to reduce it is with calcium chloride flakes. Since calcium chloride is an acidifying salt, it is usually undesirable in the treatment of hypocalcaemia of renal insufficiency. By adding salt chlorides to your beer, you not only reduce the pH level but have the benefit of the chloride ions working to promote the sweetness, or mellowness of the … Calcium Chloride or CaCl2 is a salt, which will completely dissolve into Ca2+ and 2Cl- in an aqueous solution. Calcium chloride dihydrate, puriss., meets analytical specification of Ph. Eur., USP, FCC, E509, 99-103%, <=0.0001% Al Calcium chloride dihydrate, suitable for cell culture, suitable for insect cell culture, suitable for plant cell culture, >=98% 3 Chemical and Physical Properties 3.1 Computed Properties Calcium chloride injection is irritating to veins and must not be injected into tissues, since severe necrosis and sloughing may occur.
