Question
Which of the following relation(s) is/are true for alkaline solution?
Options
A.$pH > \frac{pK_{w}}{2}$
B.pH > pOH
C.$pOH < \frac{pK_{w}}{2}$
D.pH < pOH
Solution
For basic solution: $\left\lbrack H^{+} \right\rbrack < \left\lbrack OH^{-} \right\rbrack\text{ and }\left\lbrack H^{+} \right\rbrack < \sqrt{Kw}$
$\therefore P^{H} > P^{OH}\text{ or }P^{H} > \frac{P^{Kw}}{2}\text{ or }P^{OH} < \frac{P^{Kw}}{2}$
