Acids vs Bases In chemistry‚ when some elements are mixed‚ the compounds that are formed can be classified depending on its characteristics‚ just like acids and bases. Acids are defined as compounds that donate a hydrogen ion‚ H+‚ to another compound. Bases are the chemical opposite of acids. They both are different in many ways. One way in which acids and bases differ is the pH and the pOH. The pH is a number used to denote the hydrogen-ion concentration‚ or the acidity‚ of a solution. In the
