Final answer:
The chemical equation for the ionization of dimethylamine in aqueous solution is (CH3)2NH + H2O -> (CH3)2NH2+ + OH-.
Step-by-step explanation:
The chemical equation for the ionization of dimethylamine, (CH3)2NH, in aqueous solution is:
(CH3)2NH + H2O → (CH3)2NH2+ + OH-
This equation represents the reaction of dimethylamine with water, resulting in the formation of the dimethylammonium ion (CH3)2NH2+ and the hydroxide ion OH-. This reaction is a form of acid-base chemistry, where dimethylamine acts as a base by accepting a proton from water and forming its conjugate acid, dimethylammonium ion. The hydroxide ion is the conjugate base of water.
