WebThis constant, K a, is called the acid ionization constant.It can be determined by experiment and each acid has its own unique value. For example, acetic acid's value is 1.77 x 10¯ 5. From the chemical equation above, it can be seen that H 3 O + and Ac¯ concentrations are in the molar ratio of one-to-one. This will have an important consequence as we move …
