Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7.35, and alkalosis refers to an excess of base in the blood that causes the pH to rise above 7.45. Many conditions and diseases can interfere with pH control in the body and cause a person's blood pH to fall outside of healthy limits.
pH is a measure of acidity or alkalinity of a solution. The level of acidity or alkalinity of a solution is expressed as a number from 1 to 14 on the pH scale. The lower the pH number, the more acidic the solution is. The higher a pH number, the more alkaline (or basic) the solution is. A pH measurement of 1 would be the most acidic, 7 neutral, and 14 the most alkaline. The pH scale is logarithmic rather than arithmetic or linear. This means that moving one unit either way on the pH scale results in a 10-fold increase in the degree of alkalinity or acidity.
