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 is :

TestHub · Accepted Answer

When 10 ml , 2 M NaOH solution is added to 20 ml of 1 M HCl solution : NaOH + HCl → NaCl + H 2 ​ O Initial : MV = 2 × 0.1 MV = 1 × 0.2 = 0.2 mole = 0.2 mole Final 0 0 ∴ Resulting solution becomes neutral. Now when 10 mol of above solution is poured into a flask containing 2 mole HCl and made solution 100 ml will distilled water. Molarity of HCl = 100 2 ​ × 1000 = 20
