Question

determine whether the following salts when dissolved in water would make the solution acidic, basic or remain neutral. when making solution acidic or neutral write acid base reaction causing the soultion to become acidic or basic.

a. KC2H5O2

B. NaNO3

C. NH4NO3

D.NH4F

E.NaHPO4

F. NaCL

G.K2CO3

H.NH4NO3

I. NH4HSO4

Answer 1

a) salt of weak acid and strong base , thus anionic hydrolysis to give BASIC solution.

C2H5O2- + H2O ------------> HC2H5O2 + OH-

b) neutral

salt of strong acid and strong base

c) acidic

salt of weak base NH4OH and strong acid HNO3

cationic hydrolysis makes it acidic

NH4+ + H2O -------------> NH4OH + H+

d) can be neutral  

salt of weak acid and weak base . Both anion and cation undergo hydrolysis

NH4 + + F- +H2O ---------------> NH4OH + HF

e) basic

salt of strong base NaOh and weak acidH3PO4

H2PO4- + H2O -----------> H3PO4 + OH- anionic hydrolysis

f) neutral

salt of strong acid HCl and strong base NaOH

g) basic

salt of weak acid H2CO3 and strong base KOH

anionic hydrolysis

CO3^-2 + H2O --------> HCO3- + OH-

h) acidic

salt of weak base NH4OH and strong base HNO3

cationic hydrolysis

NH4+ + H2O -------------> NH4OH + H+

i) acidic

salt of weak base NH4OH and strong acid H2SO4

cationic hydrolysis

NH4+ + H2O -------------> NH4OH + H+
