WebMar 4, 2024 · A Crash Course on Logarithms. The “p” in pH, pKa, and pI denotes the negative logarithm, to base 10, of the parameter in question. Logarithms transform a nonlinear series of values into a linear series. E.g., the logarithm (to base 10) of, 10, 100, 1000, and 10,000 is 1, 2, 3, and 4 respectively. A quick math rule to jot down in your notebook. 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. Solutions having the value of pH equal to 7 on pH scale are known as neutral solutions.
