JEE Mains · Chemistry · STD 12 -1. Solution and colligative properties
10 mL of 2 M NaOH solution is added to 20 mL of 1 M HCl solution kept in a beaker. Now, 10 mL of this mixture is poured into a volumetric flask of 100 mL containing 2 moles of HCl and made the volume upto the mark with distilled water. The solution in this flask is _______.
- A 0.2 M NaCl solution
- B 20 M HCl solution
- C 10 M HCl solution
- D Neutral solution
Answer & Solution
Correct Answer
(B) 20 M HCl solution
Step-by-step Solution
Detailed explanation
When \(10 \mathrm{ml}, 2 \mathrm{M} \mathrm{NaOH}\) solution is added to 20 ml of 1 M HCl solution : \(\mathrm{NaOH}+\mathrm{HCl} \rightarrow \mathrm{NaCl}+\mathrm{H}_2 \mathrm{O}\) Initial : MV \(=2 \times 0.1 \quad \mathrm{MV}=1 \times 0.2\)…
