Interpretation Introduction

Interpretation:

The solution that is used to separate the cations in the aqueous solution containing barium and calcium ion having molarity 0.050 M.

Concept introduction:

The molarity of solution is defined as number of moles of solute in 1L of the solution.

$M=\frac{n}{V}$

Here, n is number of moles of solute and V is volume of solution in L.
