Analytical chemistry is concerned with investigation of the quantitative and/or qualitative characteristics of a given sample. For instance, an analytical chemist may qualitatively determine what the various polycyclic aromatic hydrocarbons in a tar sample are, and may also quantitatively analyze the concentrations of each species in the sample.

How can one identify an unknown substance in chemistry?
One can identify an unknown substance in chemistry by conducting various tests such as spectroscopy, chromatography, and chemical reactions to determine its properties and compare them to known substances.
How can one identify unknown substances in chemistry?
One can identify unknown substances in chemistry through various methods such as spectroscopy, chromatography, and chemical tests. These techniques involve analyzing the physical and chemical properties of the substance to determine its composition and characteristics.
What properties do scientists look for to identify an unknown substance?
Scientists look for properties such as density, boiling point, melting point, solubility, conductivity, and reactivity to help identify an unknown substance. By comparing these properties to known data in a database, scientists can often determine the identity of the unknown substance.
How can one test an unknown substance to identify it?
To identify an unknown substance, one can conduct tests such as spectroscopy, chromatography, and chemical reactions to determine its properties and composition. These tests can help determine the substance's characteristics and compare them to known substances for identification.
Which absorption spectrum is equivalent to a fingerprint of a substance?
The UV-Vis absorption spectrum is often referred to as the fingerprint of a substance because it provides a unique pattern of absorption peaks and intensities that is specific to that substance. This spectrum is commonly used to identify and characterize unknown compounds in chemistry.

What happens when you add sodium carbonate to an unknown substance?
Sodium carbonate can react with acidic components in the unknown substance to form carbon dioxide gas, which may result in fizzing or effervescence. This reaction can help identify the presence of acidic compounds in the unknown substance.
Where can quantitative analysis be used in chemistry?
Forensics. QA is used to find what sort of chemical or compound is present in an unknown substance.
Why Do You Think Scientists Can Use The Basic Properties Of Matter To Help Identify An Unknown Substance?
Because if a substance can't be known then it has to prove its mass and volume
What can be used to identify an unknown substance?
Just about any property that can be observed or measured can help you reduce the number of options.
How can density be used to determine the identity of a substancce?
Density can be used to determine the identity of a substance by comparing the density of the unknown substance to the known densities of different substances. Each substance has a characteristic density, so if the density of the unknown substance matches that of a known substance, it can help identify the unknown substance.
