Chemical composition of the substances can be determined according to the two types. One is qualitative and the other is quantitative.
Qualitative Analysis - This is a type of chemical analysis which is execute to identify the components of the mixture.
These are of different types. They are-
Quantitative Analysis - This is a type of chemical analysis which is used to measure the amount of the components present in a mixture.
Quantitative analysis is bunches of chemical experiment by the identification of the components of the mixture. These are analyse by-
Different Reagent – Different reagents are used to identify the components of the solution. Specifically metal, non-metal portion of the mixture.
UV Spectroscopy - By the spectroscopy components can be identify by the absorption of the particles present in it.
Structure of the components can be determined by the –
X Ray Defraction - This is used for the structural analysis of the components.
Chromatography - Chromatographyis a technique by which components are separated by the molecular weight of the mixture.
Crystallography - This technique is used for the determination of structure.
Different types of method are there to make quantitative analysis. These are-
Titration process - Titration is a method by which we are able to measure the amount of the acid, base, salts etc. Examples of this titration are suppose sulphuric acid can neutralise the X amount of base sodium hydroxide. From this type of experiment it is found that how much amount of acid is able to neutralise the how much amount of alkali.
Spectroscopy - UV spectroscopy is a type of instrument by which we can measure the amount of the components by their absorption spectrum.
