The pH Scale A Way to Quantify Acidity and Basicity

The pH scale is a compact way to specify the acidity of a solution. We define pH as the negative of the log of the hydronium ion concentration  [Pg.708]

Notice that we report Ihe pH to two decimal places here. This is because only the numbers to the right of the decimal point are significant in a logarithm. Because our original value for the concentration had two significant figures, the log of that number has two decimal places. [Pg.708]

If the original number had three significant digits, the log would be reported to three decimal places. [Pg.708]

0 is 10 times more acidic than a plum with a pH of 3.0 and 100 times more acidic than a cherry with a pH of 4.0. [Pg.709]

Calculate the pH of each solution at 25 °C and indicate whether the solution is acidic or basic. [Pg.709]
