WBJEE · Chemistry · Ionic Equilibrium
Equal volume of two solutions A and B of a strong acid having \(\mathrm{pH}=6.0\) and \(\mathrm{pH}=4.0\) respectively are mixed together to form a new solution. The pH of the new solution will be in the range
- A between 5 and 6
- B between 6 and 7
- C between 4 and 5
- D between 3 and 4
Answer & Solution
Correct Answer
(C) between 4 and 5
Step-by-step Solution
Detailed explanation
\(\mathrm{pH}=6 \quad \therefore\left[\mathrm{H}^{+}\right]=10^{-6} \mathrm{M}\) Let volume is 1 L \(1 \mathrm{~L} 10^{-6} \mathrm{M}\) SA contains \(10^{-6}\) moles \(\mathrm{H}^{+}\) \(\mathrm{pH}=4 \quad \therefore\left[\mathrm{H}^{+}\right]=10^{-4} \mathrm{M}\)…
