Dimethyl amine (CH_3)_2NH is weak base and its ionization constant 5.4 xx 10^(-5). Calculate [OH^(-)], [H_3O^+], pOH and pH of its 0.2 M solution at equilibrium.

Dimethyl amine (CH_3)_2NH is weak base and its ionization constant 5.4

1.	Dimethyl amine (CH_3)_2NH is weak base and its ionization constant 5.4 xx 10^(-5). Calculate [OH^(-)], [H_3O^+], pOH and pH of its 0.2 M solution at equilibrium.
Answer» SOLUTION :`[OH^-]=1.04xx10^(-3)` M, `[H_3O^+]= 9.6xx10^(-12)` M , POH= 2.98 , pH=11.02
