WebpH Definition. pH is defined as the negative logarithm of H + ion concentration. Hence the meaning of the name pH is justified as the power of hydrogen. We know that all the acids and bases do not react with the same chemical compound at the same rate. Some react very vigorously, some moderately while others show no reaction. The concentration of hydrogen ions and pH are inversely proportional; in an aqueous solution, an increased concentration of hydrogen ions yields a low pH, and subsequently, an acidic product. By definition, an acid is an ion or molecule that can donate a proton, and when introduced to a solution it will react with water molecules (H2O) to form a hydronium ion (H3O ), a conjugate acid of water. For simplistic reasoning, the hydrogen ion (H ) is often used to abbreviate the hydroniu…
