B Flashcards
The power of _____ comes from its ability to separate a mixture of compounds or analyte and determine their respective identity (chemical structure) and concentration.
CHROMATOGRAPHY
The power of chromatography comes from its ability to __________ and determine their respective identity (chemical structure) and concentration.
SEPARATE A MIXTURE OF COMPOUNDS OR ANALYTE
the technique for the separation, purification, and testing of compounds.
CHROMATOGRAPHY
Chromatography is the technique for the _____, _____, _____, of compounds.
SEPARATION, PURIFICATION, TESTING
Chroma meaning
COLOUR
Graphein meaning
TO WRITE
is a separation method where the analyte is combined within a liquid or gaseous mobile phase.
CHROMATOHRAPHY
Separation of colored compounds on a suitable adsorbent.
CHROMATOGRAPHY
may be defined as a process in which a solution of a mixture containing inert material, drug principles, and impurities is separated into its components while moving through a bed of fixed.
CHROMATOGRAPHY
different compounds are adsorbed on the adsorbent to different degrees based on the absorptivity of the component.
ADSORPTION CHROMATOGRAPHY
A mobile phase is made to move over a stationary phase, thus carrying the components with higher absorptivity to a lower distance than that with lower absorptivity.
ADSORPTION CHROMATOGPRAHY
the mixture of substance is separated into its components with the help of glass plate coated with a very thin layer of adsorbent, such as silica gel and alumina.
THIN LAYER CHROMATOGRAPHY
the technique used to separate components of a mixture using a column of suitable adsorbent packer in a glass tube.
COLUMN CHROMATOGRAPHY
the material place in the column to adsorb the drug
ADSORBENT
Examples of Adsorbent
PURIFIED SILICEOUS EARTH, ACTIVATED ALUMINA, SILICA GEL and CALCIUM CARBONATE
a solvent use in the separation of substance
ELUANT
A solution obtained by elution
ELUATE
a continuous differential partitioning of components of a mixture into a stationary phase and mobile phase takes place
PARTITION CHROMATOGRAPHY
The examples of partition chromatography can be seen in ?
PAPER CHROMATOGRAPHY
In this process, chromatography paper is useful as a stationary phase which is suspended in a mixture of solvents that act as a mobile phase
PARTITION CHROMATOGRAPHY
Is the method of separation of any organic components present in an aqueous solution. In this process, we use an organic solvent for which the solubility of the desired compound is more than compared to that in water.
DIFFERENTIAL EXTRACTION
Is mainly used for separation, isolation, and purification of proteins from complex sample matrices.
CHROMATOGRAPHY
Branch of electrochemistry which deals with the study and measurement of electrode potentials.
POTENTIOMETRY
Are based on the transfer of electron between the titrant and the analyte, these type of titration are usually followed by potentiometry, although dyes which change color when oxidised by excess titrant may be used.
REDOX TITRATION
A type of chemical reaction that involves a transfer of electrons between two species.
OXIDATION-REDUCTION (REDOX) REACTION
Is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
OXIDATION-REDUCTION REACTION
Are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.
REDOX REACTIONS
the ion or molecule that accepts electrons is called?
OXIDIZING AGENT
by accepting electrons it oxidizes other species
OXIDIZING AGENT
The ion or molecule that donates electrons is called the?
REDUCING AGENT
by giving electrons it reduces the other species
REDUCING AGENT
A good example of redox reaction is the _____, in which iron atoms in ferric oxide lose (or give up) OO atoms to AIAI atoms, producing Al2O3Al2O3
THERMITE REACTION
Is a measure of how thermodynamically favorable it is for a compound to gain electrons.
