Dimethylamine dissociation in water

Dimethylamine is an organic compound with the formula (CH3)2NH. This secondary amine is a colorless, flammable gas with an ammonia-like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%. An estimated 270,000 tons were produced in 2005. WebAug 14, 2024 · The equilibrium constant for this dissociation is as follows: K = [H3O +][A −] [H2O][HA] As we noted earlier, because water is the solvent, it has an activity equal to 1, so the [H2O] term in Equation 16.4.2 is actually the aH2O, which is equal to 1. Again, for simplicity, H3O + can be written as H + in Equation ???.
