A

PARTITION CHROMATOGRAPHY

19
Q

The examples of partition chromatography can be seen in ?

A

PAPER CHROMATOGRAPHY

20
Q

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

A

PARTITION CHROMATOGRAPHY

21
Q

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.

A

DIFFERENTIAL EXTRACTION

22
Q

Is mainly used for separation, isolation, and purification of proteins from complex sample matrices.

A

CHROMATOGRAPHY

23
Q

Branch of electrochemistry which deals with the study and measurement of electrode potentials.

A

POTENTIOMETRY

24
Q

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.

A

REDOX TITRATION

25
Q

A type of chemical reaction that involves a transfer of electrons between two species.

A

OXIDATION-REDUCTION (REDOX) REACTION

26
Q

Is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

A

OXIDATION-REDUCTION REACTION

27
Q

Are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

A

REDOX REACTIONS

28
Q

the ion or molecule that accepts electrons is called?

A

OXIDIZING AGENT

29
Q

by accepting electrons it oxidizes other species

A

OXIDIZING AGENT

30
Q

The ion or molecule that donates electrons is called the?

A

REDUCING AGENT

31
Q

by giving electrons it reduces the other species

A

REDUCING AGENT

32
Q

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

A

THERMITE REACTION

33
Q

Is a measure of how thermodynamically favorable it is for a compound to gain electrons.

A

REDUCTION POTENTIAL
