MCQ
A solution of weak acids is diluted by adding an equal volume of water. Which of the following will not change
  • A
    Strength of the acid
  • ✓
    The value of $[{H_3}{O^ + }]$
  • C
    $pH$ of the solution
  • D
    The degree of dissociation of acid
✓

Answer

Correct option: B.
The value of $[{H_3}{O^ + }]$
(b) The value of ${H_3}{O^ + }$ ions will not changed.

$C{H_3}COOH + {H_2}O  \rightleftharpoons  C{H_3}CO{O^ - } + {H_3}{O^ + }$.
