WebDec 3, 2024 · The aqueous solutions of these salts are neutral with pH value of 7. (ii) Salts of strong acids and weak bases : Aluminium chloride (AlCl 3 ), copper sulphate (CuSO 4 ), zinc sulphate (ZnSO 4 ), etc., are salts of this category. The aqueous solutions of these salts are acidic with pH value less than 7. (iii) Salts of weak acids and strong bases ... WebThe pH is then calculated using the expression: pH = - log [H 3 O +]. Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. The hydronium ion concentration is 0.0025 M. Thus: pH = - log (0.0025) = - ( - 2.60) = 2.60 Top Calculating the Hydronium Ion Concentration from pH

WebJan 30, 2024 · Summary. We have learned that an ionization constant quantifies the degree a substance will ionize in a solution (typically water). K a, K b, and K w are constants for acids, bases, and finally water, respectively and are related by. However, these constants are also used to find concentrations as well as pH.
