The quantitative analysis of oxide in wide range is a high precision quantitative analysis applicable for many oxides in silicate and carbonate materials,which was based on the conception called apparent concentration(the linear correlation principle between element concentration and spectral intensity) of theoretical α method.

So many students are puzzled with the correct comparison between the relations of the particle consistency in electrolytic solution that correctly grasping it can help understand the knowledge of hydrolysis and electrolysis in order to improve students’ comprehensive analytic capability.
