Importance of acids and bases

In our bodies, in our homes, and in our industrial society, acids and bases play key roles. Proteins, enzymes, blood, genetic material, and other components of living matter contain both acids and bases.

We seem to like the sour taste of acids; we add them to soft drinks, salad dressings, and spices. Many foods, including citrus fruits and some vegetables, contain acids.

We perceive bases as bitter and slippery. Therefore, foods with a high pH are not common.

Cleaners in our homes contain acids or bases. Acids and bases play important roles in the chemical industry.
