Analytical Chemistry
It is the science of obtaining, processing, and communicating information about the composition and structure of matter.
Analytical Chemistry
It is the art of science of determining what matter is and how much of it exists.
Qualitative Chemistry
It is the branch of chemistry dealing with the determination of elements or ingredients of which a compound or mixture is composed.
Quantitative Chemistry
It is the branch of chemistry dealing with the determination with the amount or percentages of one or more constituents of a sample.
Qualitative Chemistry
A process in analytical chemistry used to separate and detect cations and anions in a sample substance.
Quantitative Chemistry
A process in analytical chemistry that involves measurement of results such as quantities of substances produced.
Reaction

Reagent
It is a substance used in a chemical reaction to detect, measure, examine, or produce other substances.
Precipitate
It is any insoluble substance that is produced after a certain reaction.
Residue
It is a portion of a solid remaining after partial solution by a reagent.
Residue
A quantity or body of matter remaining after evaporation, combustion, distillation, etc.
Filtration
The act or process of filtering, especially the process of passing a liquid or gas, such as air, through a filter in order to remove solid particles.
Test Solution
A solution of some reagent, in definite strength, used in chemical analysis or testing.
Clear Solution
A solution that isn’t turbid or cloudy.
Colorless Solution
A solution that is not colored.
Test
It is a laboratory procedure designed to show the presence or absence of some substances.
Positive Test
It is a type of test that indicates that the substance being found is present.
Negative Test
This type of test indicates that the substance being found is absent.
Blank Test
It is a test carried out under specified conditions with all reagents with exception of determined substances to account for consent of this substance in reagents used.
Control Test
A blank test to which a known sample of the ion under consideration has been added.
Specific Test
A test given by one and only substance.
Centrifugation

Indicator Paper
It is used to determine the acidity of a solution.
Flame Test
This test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a bunsen burner.
