QJEEM03Chd5f0: JEE Main 2003 Chemistry - Class 11 JEEM03Chd5f0 Solution: 25 ml of a solution of barium hydroxide on titration with a 0.1 …

25 ml of a solution of barium hydroxide on titration with a 0.1 molar solution of hydrochloric acid gave a litre value of 35 ml. The molarity of barium hydroxide solution was

Multiple Choice Options

  • A 0.14
  • B 0.28
  • C 0.35
  • D 0.07

Step-by-Step Verified Solution

Ba(OH)2 + 2HCl(aq) → BaCl2(aq) + 2H2O(l)

Assume molarity of Ba(OH)2 = M

No of moles of Ba(OH)2 present = 25×M

No of moles of HCl present = 35×0.1

Stoichiometric coefficient of Ba(OH)2 = 1

Stoichiometric coefficient of HCl = 2

∴ 25×M1 = 35×0.12

⇒ M = 0.07
