If you are referring to chemical purity by grade, I suggest you research the following terms:
ACS Grade (American Chemical Society) - highest level of purity
Reagent grade - Almost as stringent as ACS
USP Grade - Equivalent to ACS for many drugs
NF Grade (National Formulary) - Equivalent to ACS for many drugs
Laboratory Grade
Purified Grade
Technical Grade
The unit of the equilibrium constant in a chemical reaction is dimensionless.
Bleach is a mixture, typically made up of sodium hypochlorite and water. It is not a pure substance because it contains more than one type of chemical component.
The chemical grades chart provides information about the purity and quality of chemicals, including the grade, description, and specifications of each chemical.
A chemical unit involved in a process is typically referred to as a molecule. A molecule is the smallest unit of a chemical compound that retains the chemical properties of that compound. It is made up of two or more atoms bonded together.
The purity of Ferric and Non-Ferric alum can be determined by conducting a chemical analysis to measure the percentage of the specific compound in the sample. This can be done using techniques such as titration, spectroscopy, or chromatography to quantitatively determine the purity of the sample. It is important to compare the results obtained from the analysis with the known standards to assess the purity accurately.

No, boiling points and freezing points are physical properties.
You are perhaps taking medicine? The answer would depend on the sustance being taken; a unit of insulin is not the same as a unit of Vitamin A.

Chemical analysis is used to test the purity of materials. We know today a very great number of analysis methods.
A carat is a unit of mass, or purity, not of length. The two units are therefore incompatible.
The purity is determined by chemical analysis.
The purity is determined by chemical analysis.
After a detailed chemical analysis the purity is correctly evaluated.
