One has a solution Sa of ethanoic acid of concentration Ca=1×10^-2 mol/l and pH=3.4
One mixes a volume Va=60ml of the solution Sa of ethanoic acid with a volume Vb1=20ml of the Sb1 solution of ammonia of concentration Cb1=2×10^-2 mol/l. The pH is 5
One has a soutions of weak bases :
Sb1 solution of ammnia
Sb2 of mythelamine .Cb2=1.5×10^-2
Is ammonia a weaker base than methylamine. Justify
