WebMar 26, 2016 · Acids are molecules that can split apart in water and release hydrogen ions. A common example is hydrochloric acid (HCl). When HCl is added to water, it splits apart into H (+) and Cl (-), increasing the number of hydrogen ions in the water–HCl solution. Bases are molecules that can split apart in water and release hydroxide ions. WebDefinition of pH: pH is defined as the negative of logarithm (base 10) of the hydrogen ion concentration. It is defined as the logarithm of the reciprocal of the hydrogen ion concentration. All vital activities are affected by H + concentration.
