1.
A.write a chemical equation which goes with thestatement:
i) Kb= 4.3 X 10-10 for aniline(C6H5NH2)
ii)Kb = 2.1 X 10-4 for carbonate ion
B. Kb =1.3 X 10-3 forC5H11N and kb= 6.3 x 10-5 for N(CH3)3
i) Which base is the stronger base in water
ii) For the same solute concentration, which base has the largerequilibrium OH- concentrations?How did you decide?
C. Reaction of amide ion (NH2-),ethoxide ion (OCH2CH3-), methoxide ion (OCH3-), hydride ion (H-),or oxide ion (O2-) with water gives hydroxide ion as oneproduct , for each ion, the reaction goes to completion.
i) For each of these ions write a net ionic equation for thereaction of the ions with water.
ii) is a salt supplying one of these ions a strong base or aweak acid?Explain.
