MCQ
A base dissolved, in water, yields a solution with a hydroxyl ion concentration of $0.05\,mol\,litr{e^{ - 1}}$. The solution is
- ✓Basic
- BAcid
- CNeutral
- DEither $(b)$ or $ (c)$
✓
Answer
Correct option: A.
Basic
(a) $[O{H^ - }] = 0.05 = 5 \times {10^{ - 2}}M$
$pOH = 2 - \log 5 = 1.3$
$pH + pOH = 14$
$pH = 14 - 1.3 = 12.7$
