An Acid Neutralizing Capacity is Measure of ability of a Base (e.g. water or soil) to resist changes in pH.

Acid rain is the result of sulfur dioxide (SO2) and nitrogen oxides (NOx) reacting in the atmosphere with water and returning to earth as rain, fog, or snow. Broadly used to include both wet and dry deposition. The acid rain page provides a great deal of information about this issue.

An Acid Rinse is Part of the equipment cleaning process for stainless steel and rubber parts, removes fat, protein and minerals and also reduces bacteria.

An Acid Solution is any water solution that has more hydrogen ions (H+) than hydroxide ions (OH-); any water solution with a pH less than 7.

See basic solution, neutral solution.

Acidic is the condition of water or soil that contains a sufficient amount of Acid substances to lower the pH below 7.0.
