Concept explainers
Interpretation:
The ions or molecules present in the aqueous solution of the oxalic acid are to be determined. The identification of the ion that is present in the lowest concentration id to be done.
Concept Introduction:
The chemical substance which releases hydrogen ion in the solution is known as acidic substance. In such compounds, the hydrogen atom is attached to an electronegative atom. Thus, it readily loses hydrogen ions in the solution.
