25 ml of a solution of barium hydroxide on titration with 0.1 molar solution of hydrochlroric acid gave a titre value of 35 ml . The molarity of sodium hydroxide is ?
We assess the following stoichiometric equation:
And thus 2 equiv acid are required to neutralize each equiv barium hydroxide.
And, thus, by the given stoichiometry, there was an initial concentration of .......
