Answer 1

The scientific study of matter's characteristics and behaviour is known as chemistry. It is a natural science that studies the components that make up matter, as well as the compounds made up of atoms, molecules, and ions: their composition, structure, characteristics, and behaviour, as well as the changes that occur when they combine with other things. Chemistry is a topic that falls between physics and biology in terms of breadth. It is frequently referred to as the "core science" since it provides a fundamental framework for comprehending both basic and applied scientific fields.

Complete answer:
Analytical chemistry is the study and use of equipment and procedures for separating, identifying, and quantifying materials. Separation, identification, and quantification may be used alone or in combination with other methods in practise. Separation is the process of isolating analytes. Quantitative analysis determines the numerical quantity or concentration, whereas qualitative analysis identifies analytes. Classical wet chemical techniques and contemporary instrumental methods make up analytical chemistry. Separations such as precipitation, extraction, and distillation are used in traditional qualitative techniques. Color, odour, melting point, boiling point, solubility, and radioactivity can all be used to identify a substance. Quantitative analysis that employs mass or volume changes to measure amount is known as traditional quantitative analysis. Chromatography, electrophoresis, and field flow fractionation are some of the instruments that may be used to separate material. Then, using light interaction, heat interaction, electric fields, or magnetic fields, qualitative and quantitative analysis may be conducted, typically with the same device.

Note:
An analyte may often be separated, identified, and quantified using the same equipment. Improvements in experimental design, chemometrics, and the development of novel measuring instruments are also priorities in analytical chemistry. Analytical chemistry is used in a variety of fields, including health, research, and engineering.
