The pH or acidity of a solution is important in chemistry and biochemistry.

In the Chemical Industry
The efficient production of nylon, as well as other modern fibers depends on rigid pH control.

In Biochemistry
The pH of our blood is normally controlled to within a few tenths of a pH unit by our body chemistry. If our blood pH changes as much as half a pH unit, serious illness will result. Proper skin pH is essential for a healthy complexion. The pH of one's stomach directly affects the digestive process.

In Agronomy
The pH of the soil regulates the availability of nutrients for plant growth, as well as the activity of soil bacteria. In alkaline soils ( pH 8 and above ) the amount of nitrogen, phosphorus, iron and other nutrients in solution become so low that special treatment is necessary to insure proper growth.

In Food Science
The efficient production of food products depends upon careful pH control. The proper curd size, uniformity, and structure of cottage cheese is directly related to the pH at cutting time. Yeast can ferment and leaven a dough only within certain pH limits. Jelly will not gel properly unless the pH is in the 3.5 region.

In the Pulp and Paper Industry
pH control is essential to the proper operation of bleaching plants and wet-end processes. Also, in order to conform with environmental protection regulations, the pH of wastewater from these plants must be controlled.

In Chemical Research and Engineering
Accurate pH measurement is necessary to the study of many chemical processes. The researcher needs to know the pH at which a chemical reaction proceeds at its fastest in order. to understand the reaction. The engineer uses the information to develop practical commercial processes.

In Environmental Research and Pollution Control
The pH of a river or lake is important in maintaining a proper ecological balance. The pH of the water directly affects the physiological functions and nutrient utilization by plant and animal life. Extremes in pH can reduce a lake to a lifeless, smelly bog.

Protecting our waterways requires constant monitoring of industrial effluent. Plating and metal finishing plants tend to produce acidic wastewater, as do mining operations, Chemical plants often have very alkaline wastewater. pH measurements are used as a guide to the proper neutralization of these plant wastes, as well as to monitor the final effluent quality. Occasionally, an acidic stream can be combined with an alkaline stream to produce a final stream, which is close to neutral. pH measurements assure the proper management of this cost saving technique.
