Scientists use the pH scale to represent the level of acidity or alkalinity of a liquid. This is based on the molar concentration of hydrogen ions, [H]. Since the mole per liter (mol/L), a logarithmic scale is used to compute pH. The formula values of [H+] vary over a large range, 1 x 10° mole per liter to 1 × 10 -14 pH=- -log[H+] represents the pH of a liquid as a function of its concentration of hydrogen ions, [H*]. The pH scale ranges from 0 to 14. Pure water is taken as neutral having a pH of 7. A pH less than 7 is acidic. A pH greater than 7 is alkaline (or basic). For this exercise, use the formula for pH.
