Ph of ionic salts

WebApr 20, 2016 · 7. Aqueous solution of magnesium sulfate is going to be slightly acidic, and there is no need to even go to the lab to test it. M g S O X 4 is a salt formed by a weak base and a strong acid (both dibasic), so there is a two-step hydrolysis of magnesium cation. First and primary step is the formation of a basic salt: WebAny acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC 2 H 3 O 2 is an example of a weak acid: HC 2 H 3 O 2 → H + (aq) + C 2 H 3 O 2− (aq) (~5%) Because this reaction does not go 100% to completion, it is more appropriate to write it as an equilibrium:
