Question
Indicate whether or not each of the following ionic compounds will undergo hydrolysis and predict whether the resulting solution pH will be acidic, basic, or indeterminate (both ions undergo hydrolysis). (a) Co(CIO3)2 acidic hydrolysis basic hydrolysis indeterminate hydrolysis no hydrolysis (b) PbSO4 acidic hydrolysis basic hydrolysis indeterminate hydrolysis o no hydrolysis (c) LiCI acidic hydrolysis basic hydrolysis indeterminate hydrolysis no hydrolysis (d) CoCO acidic hydrolysis basic hydrolysis indeterminate hydrolysis no hydrolysisExplanation / Answer
a) Co(ClO3)2
a salt of weak base Co(OH)2 and weak acid HClO3
Thus both cation Co+2 and anion ClO3- undergo hydrolysis.
option 3 - intermediate hydrolysis
b)PbSO4
a salt of weak base Pb(OH)2 and strong acid H2SO4
ONly cation Pb+2 undergoes hydrolysis. to give acidic solution.
option 1 - acidic hydrolysis
c)LiCl
a salt of strong base LiOH and strong acid HCl
No hydrolysis
option 4
d) C0CO3
A salt of weak base Co(OH)2 and weak acid H2CO3
Thus both cation Co+2 and anion CO3-2 undergo hydrlysis
option 3 - intermediate hydrolysis
