Correct answer: B. 20 M HCl solution

When 10 ml, 2 M NaOH solution is added to 20 ml of 1 M HCl solution : NaOH+HCl arrow 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=(2)/(100) × 1000=20
