Common components found in acids include hydrogen, oxygen, and carbon atoms. Hydrogen and oxygen are key components of many common acids, including hydrochloric acid (HCl), sulphuric acid (H2SO4), and nitric acid (HNO3). Carbon atoms are found in carboxylic acids, such as acetic acid (CH3COOH). Other common components found in acids can include nitrogen, chlorine, and phosphorus atoms.
Aqueous solution of acids contain ions, such as hydrogen (H+) and hydroxide (OH-) ions. These ions act as the base of the acid, allowing it to react with other molecules and form new compounds. Acids can also contain other molecules, such as sulphur atoms, which can be found in sulphuric acid (H2SO4).
