In this paper

Combining the calculation of equilibrium constants and the use of mathematical diagrams to deeply analyze the concentrations of some particles in the acid salt solution represented by NaHCO3. It is concluded that the concentrations of some particles in acid salts is not only related to the degree of ionization and hydrolysis

but also related to the initial concentration of acid salts. This paper scientifically analyzes and deeply explores the difficulty of the comparison of some particles concentration in acid salts

and correcting the common wrong thinking of the the comparison of the concentrations of some particles.
