Triethanolamine is used to trap carbon dioxide that is emitted from power plants. When it is dissolved in water it undergoes a Brønsted acid/base reaction to reach equilibrium, as shown in the image. The amine reacts with water to give an ammonium cation and the hydroxide anion. An equilibrium is established and so the ammonium cation and the hydroxide anion also react to give the amine and water.Identify the acid and the base on both sides of the Brønsted acid/base equilibrium.
