WebNov 24, 2024 · Here you have CsHSO 4. As this is a salt, it will hydrolyze in water and and so we need to look at the hydrolysis of the HSO 4- anion. HSO 4- + H 2 O ==> H 3 O + + SO 42-. Note that H 3 O + is formed so the solution will be slightly acidic (pH > 7) We need to look up the Ka or pKa for HSO 4- acting as an acid. I find it to be 1.0x10 -2.
