SATHEE: Equilibrium Question 744

Equilibrium Question 744

Question: The pH of a 0.01 M solution of a monobasic acid is four. Which one of the following statements about the acid is invorrec'

Options:

A) When a little NaOH is added, it will form a buffer solution

B) It is a weak acid

C) Its sodium salt will be acidic

D) Its sodium salt will be basic

Show Answer

Answer:

Correct Answer: C

Solution:

Concentration of monobasic acid=0.01 M $p H = 4$ If the acid is completely ionized, the pH of the acid would be $p H = - \log 0.01 = - \log 10^{- 2} = 2$ So it is a weak acid. When the sodium salt of a weak acid is dissolved, the anions will be hydrolysed giving rise to $O H^{-}$ ion concentration . The solution will be basic, So statement (3) is incorrect.
