Select all the correct statements about
(CH3)2NH as a weak base.
The chemical equation for dimethyl amine as
a weak base is:
(CH3)2NH + H20<==>
(CH3)2NH2* + OH-
The chemical equation for dimethyl amine as
a weak base is:
(CH3)2NH + H30* <==>
(CH3)2NH2*
The chemical equation for dimethyl amine as
a weak base is:
(CH3)2NH2* + OH° <==>
(CH3)2NH + H2O
The ionization constant, KA, for the
conjugate weak acid of dimethyl amine,
(CH3)2NH2* can be calculated using
the formula:
КА
kw

The ionization constant, KĄ, for the
conjugate weak acid of dimethyl amine,
(CH3)2NH2* can be calculated using
the formula:
Кв
KA =
