1. The problem statement, all variables and given/known data Which compound is more acidic? (without using pkA value) HCl or H2SO4 2. Relevant equations Electronegativity. Inductive effect. 3. The attempt at a solution Since sulfur is more electronegative compared to cholrine, H2SO4 is more acidic than HCl... So then I think of how I could use inductive effect instead of electronegativity to verify this claim. Since sulfur is more electronegative compared to oxygen it shall pull away electrons slightly, more than chlorine on hydrogen? I don't think it'll work since there are a 3 oxygens around sulfur and so the combined electronegativity outweighs that of sulfur? What do you think?
