Solution

Q4)

a) KF is the salt of strong base KOH and weak acid HF, hence the pH will be slightly basic, which is greater than 7

b) NaClO3 is the salt of strong base NaOH and strong acid HClO3, hence the pH will be neutral or equal to 7

c) NH4NO3 is the salt of weak base NH4OH and strong acid HNO3, hence the pH will be slightly acidic and will have value less than 7

d) CH3COONa is salt of strong base NaOH and weak acid CH3COOH, hence the pH will be slightly basic with value greater than 7

e) NaHCO3 is basic in nature, hence pH will be greater than 7
