MCQ
The hydrogen ion concentration of $0.001 $ $M\,\,NaOH$ solution is
- A$1 \times {10^{ - 2}}\,mole/litre$
- ✓$1 \times {10^{ - 11}}\,mole/litre$
- C$1 \times {10^{ - 14}}\,mole/litre$
- D$1 \times {10^{ - 12}}\,mole/litre$
✓
Answer
Correct option: B.
$1 \times {10^{ - 11}}\,mole/litre$
(b) $0.001\, M$ $NaOH$ means $[O{H^ - }] = {10^{ - 3}}$; $pOH = 3$
$pH + pOH = 14;\,\,pH = 14 - 3$
$pH = 11$; $[{H^ + }] = {10^{ - 11}}$ $mole-litre$$^{-1}$
