Question

200 ml of 0.5 M $H_{2}S{O}_4$ is added to 200 ml of 0.5 N $NaOH$. The solution is:

• A. basic
• B. acidic
• C. neutral
• D. none of the above

Answer 1

Answer: (B)

acidic

Millimoles of acid = $200\times 0.5\times 2=200$

Millimoles of base = $200\times 0.5=100$

So the sulphuric acid has more millimoles than sodium hydroxide.

Therefore, the solution is acidic.

Option B is correct.
