What cause acidity in acid?

Answer 1

the best answer i could find was because of its low pH number i dont know if it is right but at least it could be right

Answer 2

Acidity in acids is due to the presence of hydrogen ions (H+). When an acid dissolves in water, it releases these hydrogen ions, which then react with water molecules to form hydronium ions (H3O+). The abundance of these positively charged ions is what gives acids their characteristic sour taste and ability to react with bases.

Answer 3

The acidity or the alkalinity depend on the ions it contain.(hydrogen,hydroxide ions)

Answer 4

Acid (obviously) or too much iron can also do it.

Answer 5

Cells in the lining of your stomach secrete small amounts of hydrochloric acid. This helps digest food and kills some bacteria.
