What is the required molarity of a ba(oh)₂ solution to prepare a 1.0 m oh⁻ solution? m?

The molarity of the solution of barium hydroxide is 0.5 mol/L.

Explanation:

Given , concentration of hydroxide ion =

1.0 M of hydroxide ion means that 1 mole of hydroxide ion is present in 1 L solution.

According to reaction 1 mole of barium hydroxide gives 2 moles of hydroxide ions.

Then, 1 mole of hydroxide ion  will be given by:

of barium hydroxide

Since, there are 1 mole of hydroxide ions present 1 L of water and 0.5 moles of barium hydroxide in 1 L.

So, the molarity of the solution of barium hydroxide is 0.5 mol/L.
