![]() ![]() According to Bronsted, these substances that accept cations do not contain hydroxide ions, but they still react with water in order to increase the number of hydroxide ions. These hydroxide ions react with hydrogen ions to form water in an acid-base solution.īronsted base definition, chemistry defines base as a substance that can accept the hydrogen cations or protons. All the base definitions agree to the fact that bases react with acids.Īrrhenius base definition, chemistry defines base as a substance that gets dissociated in an aqueous solution to form hydroxide ions OH. The word base has three different definitions in chemistry, and they are Arrhenius base, Bronsted base, and Lewis base. The base is a substance that reacts with acid. Base meaning in chemistry is that base is a chemical substance that is slippery to touch, tastes bitter, and changes the colour of indicators such as litmus paper. ![]() But, the base meaning in chemistry is different. In simple words, the base meaning is that it is the foundation of something that provides support to the thing which is built on it. The term ionic compound refers to a compound containing both a negative non-metal ion and a positive metal ion linked by an ionic bond. Ionic compounds that dissolve in water and cause hydroxide ions to form are called bases.
