Question

100 ml of each of $0.5NNaOH,\frac{N}{5}HCl$ and $\frac{N}{10}{H}_{2}S{O}_4$ are mixed together. The resulting solution will be

• A. Acidic
• B. Neutral
• C. Alkaline
• D. None

Answer 1

The correct option is C Alkaline

Meq. of $NaOH=100\times 0.5=50$
Meq. of $HCl=\frac{1}{5}\times 100=20$
Meq. of $H_{2}S{O}_4=\frac{1}{10}\times 100=10$
Total meq. of acid $=20+10=30$
Total meq. of $NaOH=50$
$\therefore$ meq. of NaOH left = 50 - 30 = 20
Therefore, the correct answer will be alkaline which is in option (c).
