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. WebThe pH of a solution varies from 0 to 14. Solutions having a value of pH ranging from 0 to 7 on the pH scale are termed as acidic and the value of pH ranging from 7 to 14 on pH scale are known as basic solutions.
