JEE Main 2025 Chemistry question
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.
Answer: (2)
Solution
10mL NaOH+20mL HCl neutralize completely giving 30mL NaCl solution; final flask [HCl] = 2/(100/1000) = 20M
