Question

What is the required in molarity of a BAO H2 solution to prepare a 1.0 MOH solution

Answer 1

Answer:

0.5 M is the required molarity of a barium hydroxide solution to prepare a 1.0 M of hydroxide solution.

Explanation:

$Ba(OH)_2(aq)\rightarrow Ba^{2+}(aq)+2OH^-(aq)$

Let the molarity of barium hydroxide be x.

According to reaction  , 2 M of hydroxide ions are obtained from 1 M of barium hydroxide

Then 1.0 M of hydroxide ion swill be obtained from:

$\frac{1}{2}\times 1.0 M=0.5 M$ of barium hydroxide

0.5 M is the required molarity of a barium hydroxide solution to prepare a 1.0 M of hydroxide solution.
