Understanding pH: Acidity, Alkalinity, and Its Importance in Medicine

pH stands for "potential of hydrogen" and is a measure of the acidity or basicity of a solution. It is expressed on a scale from 0 to 14, with 7 being neutral. Values below 7 indicate acidity, while values above 7 indicate basicity.

In the context of medicine, pH is often used to assess the acid-base balance of the body or specific fluids, such as blood or urine. Maintaining a proper pH level is crucial as it affects various physiological processes, including enzyme activity, protein structure, and cell function. Disturbances in pH can lead to various health conditions, such as acidosis and alkalosis.
