pH is defined as the negative logarithmic function of the hydronium ion concentration.<\/p>\n

In simple language: pH measures the amount of acid (H) and hydroxide (OH) in water.<\/p>\n

Pure water is composed of hydrogen (H) and hydroxide (OH) ions. When they are in perfect balance, pure water is formed (H2<\/sub>O) and both are present at 10-7<\/sup>\u00a0gram equivalents (or moles) per liter. The water has a pH of 7, which is neutral.<\/p>\n

As the concentration of hydrogen (H) varies, the concentration of OH\u00a0must also vary, but in the opposite direction. By reacting in opposite directions the product of the two ions remains constant. Below is a table that demonstrates hydrogen (H) and hydroxide (OH) ions at different pH\u2019s\u201d<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
