Question

how does this acid cause a battery to work?
describe how acids and bases work in our body. they help keep our body ph balanced

Explanation:

Acids and bases in the body are involved in maintaining pH balance. pH is a measure of how acidic or basic a solution is. The body has various buffer systems (which are mixtures of acids and their conjugate bases) that resist changes in pH. For example, the bicarbonate buffer system (\(H_2CO_3/HCO_3^-\)) helps regulate the pH of the blood. When there is an excess of acid (such as from metabolic processes), the bicarbonate ion (\(HCO_3^-\)) can react with the acid to neutralize it. Conversely, if there is an excess of base, the carbonic acid (\(H_2CO_3\)) can react to neutralize the base. This helps keep the body's fluids within a narrow pH range that is optimal for biological processes.

Answer:

They help keep our body's pH balanced.
