Study Notes
Analytical Chemistry
- The main focus of analytical chemistry is to identify and quantify the chemical components of a substance.
- The primary goal of qualitative analysis is to identify the presence or absence of a particular component in a sample.
Importance of Qualitative Analysis
- Qualitative information is necessary before conducting a quantitative analysis to determine what components are present in the sample.
Distinction between Qualitative and Quantitative Analysis
- Qualitative analysis identifies the presence or absence of a component, while quantitative analysis determines the amount of each component.
Applications of Analytical Chemistry
- Analytical chemistry is most beneficial in the field of medicine, as it enables the diagnosis and treatment of diseases.
- Analytical chemistry enables us to determine the chemical composition of a substance, which is essential in various fields such as medicine, agriculture, and industry.
Gravimetric Method
- The basis of calculation in the gravimetric method is the weight of the precipitate or residue.
Electrochemical Method
- The electrochemical method involves the measurement of electrical properties like potential and current.
Historical Development of Analytical Chemistry
- Analytical chemistry has been assiduously cultivated since an early period in the history of chemistry due to its importance in understanding the chemical composition of substances.
