Determination of the pH of the solution with pH meter, instrument analysis and chemical analysis
The pH in two analysis range, is generally considered instrumental analysis. Modern instruments are carried out on the basis of chemical analysis.
Instrumental Analysis: the determination of the chemical composition, content, or structure of a substance by measuring the physical or physical and chemical properties of a substance.Chemical analysis: an analytical approach based on the chemical reactions of substances and their stoichiometric relationships.
The pH is used for solution Determination of instrument analysis.Instrumental analysis is an important branch of chemistry. It is a method of analysis based on the physical and physico-chemical properties of matter. Qualitative analysis, quantitative analysis and morphological analysis of substances were carried out by using special instruments. Instrumental analysis methods include many analytical methods, and there are currently ten kinds. Each method of analysis is based on different principles, the measured physical quantity is different, the operation process and application are also different.
