      pH = -log[H +] = log 1/[H ] The pH scale ranges from 0 to 14, with 7.0 being neutral. Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2.

      Calibrate the pH meter using standard pH buffer solutions such as pH = 4.0, 7.0, and 10.0. Place about 10 mL of solution in a small beaker and determine the pH by immersing the pH probe into the solution. Record the pH reading on the report form, rinse the pH electrode using a wash bottle, and measure the remaining solutions in the same manner.
