MCQ
How much water should be added to $200 \,c.c$ of semi normal solution of $NaOH$ to make it exactly deci normal ............ $\mathrm{cc}$
- A$200$
- B$400$
- ✓$800$
- D$600$
✓
Answer
Correct option: C.
$800$
c
(c) ${N_1}{V_1} = {N_2}{V_2}$; $\frac{1}{2} \times 200 = \frac{1}{{10}} \times {V_2}$; ${V_2} = 1000\,ml$
(c) ${N_1}{V_1} = {N_2}{V_2}$; $\frac{1}{2} \times 200 = \frac{1}{{10}} \times {V_2}$; ${V_2} = 1000\,ml$
Volume of water added $ = 1000 - 200 = 800\,ml$.
