From: AIEEE 2003
Question
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
Choose an option

Correct answer
D0.07
Step-by-step explanation
Ba(OH)2 + 2HCl(aq) BaCl2(aq) + 2H2O(l)
Assume molarity of Ba(OH)2 = M
No of moles of Ba(OH)2 present = 25M
No of moles of HCl present = 350.1
Stoichiometric coefficient of Ba(OH)2 = 1
Stoichiometric coefficient of HCl = 2
=
M = 0.07
Assume molarity of Ba(OH)2 = M
No of moles of Ba(OH)2 present = 25M
No of moles of HCl present = 350.1
Stoichiometric coefficient of Ba(OH)2 = 1
Stoichiometric coefficient of HCl = 2
=
M = 0.07
