Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. Both are divided into two categories - strong acids or bases which ionize completely in water, and weak acids or bases which ionize only partially in water.
Bases are substances that can react with acids and neutralise them. Alkalis are bases that are soluble in water. The pH scale measures how acidic or alkaline a substance is. Substances with a pH lower than 7 are acidic, those with a pH of 7 are neutral and those with a pH greater than 7 are alkaline.he chemical properties of many solutions enable them to be divided into three categories-acids, alkalis and neutral solutions. The strength of the acidity or alkalinity is expressed by the pH scale. 1  solutions with a pH less than 7 are acidic.
