a) Write a balanced chemical equation showing H2NCH(CH3)2 in aqueous solution acting as a base.
b) In water, is H2NCH(CH3)2 a strong base, a weak base, not a base, or cannot be determined? Justify Your Choice.
c) What can you conclude about the relationship between the molar solute concentration of H2NCH(CH3)2 and the molar concentration of hydroxide ion in an aqueous solution of H2NCH(CH3)2?
*I know its a weak base, because its an amine, how do i show a balanced chemical equation for this base?

The amine (isopropylamine) acts as a base because the N atom accepts a proton from H2O.
H2NCH(CH3)2 + H2O <==> +H3NCH(CH3)2 + OH-
Like all amines, the above is a weak base. All the strong bases are Group I and Group II metal hydroxides.
Because it is a weak base, it will produce only a small amount of OH- in water. Most of the isopropylamine will be present in the solution as the undissociated molecule.
