COMEDK · Chemistry · 8. Ionic Equilibrium
In a mixture of acetic acid and sodium acetate the ratio of concentrations of the salt to the acid is increased ten times. Then the pH of the solution
- A decreases ten fold
- B increases ten fold
- C increases by one
- D decreases by one
Answer & Solution
Correct Answer
(C) increases by one
Step-by-step Solution
Detailed explanation
The \(\mathrm{pH}\) of buffer solution is given as, \(\mathrm{pH}_{1}=\mathrm{p} K_{a}+\log \frac{\left[\mathrm{CH}_{3} \mathrm{COONa}\right]}{\left[\mathrm{CH}_{3} \mathrm{COOH}\right]}...(i)\) Given,…
