Explanation:
Detailed explanation-1: -That title falls to fluoroantimonic acid – a superacid mixture of antimony pentafluoride and hydrofluoric acid.
Detailed explanation-2: -As HCl is a strong acid, the H+ ion concentration after its dissociation is very high. Thus, the pH of hydrochloric acid is very low. Strong acids have pH ranging between 0-1. Thus, the pH of hydrochloric acid is expected to range between 0-1.
Detailed explanation-3: -A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0.
