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) PbCr2O7
acidic hydrolysis
basic hydrolysis
indeterminate hydrolysis
no hydrolysis
(b) MgCl2
acidic hydrolysis
basic hydrolysis
indeterminate hydrolysis
no hydrolysis
(c) NaF
acidic hydrolysis
basic hydrolysis
indeterminate hydrolysis
no hydrolysis
(d) CoCO2
acidic hydrolysis
basic hydrolysis
indeterminate hydrolysis
no hydrolysis
a) PbCr2O7 is a salt of strong acid H2Cr2O7(dichromic acid) and weak base Pb(OH)2.
Thus the anion( basic ) undergoes basic hydrolysis giving an acidic solution.
b) MgCL2 is a salt of weak base Mg(OH)2 and strrong acid , thus the basic( anionic) hydrolysis giving acidic solution.
c) NaF is a salt of strong base NaOh and weak acid HF , thus cationic(acidic) hydrolysis giving basic solution.
d) CoCO3 is a salt of weak baseCo(OH)2 and weak acid H2CO3 . thus both anion and cation (basic and acidic) hydrolysis takeplace.
Thus indeterminate hydrolysis.
