Factors Affecting An Aqueous Solution (ECS)
Transcript of Factors Affecting An Aqueous Solution (ECS)
~ In the electrolysis of aqueous solution
only one ion
is involved in the
selective discharged of ions
during the electrolysis and their ions are free to move .
~ Their ions are cation and anion .
The ion which is selected for discharged at an electrode depends on a few factors:
1 . Position of the ions in the electrochemical series .
2 . Nature of the electrode
3 . Concentration of the ion in solution .
Position of the ions in the electrochemical series (ECS)
~ The positive ions,
Na+ and H+
are attracted to the negative electrode .
~ The negative ions,
Cl- and OH-
are attracted to the positive electrode
An aqueous solution of a compound contains :
anions & cations of the compound.
hydrogen ions, H+ & hydroxide ions, OH- from the partial dissociation
(not complete ionisation)
of water molecules.
Examples of aqueous solutions and how they ionises...
* Cl- ions
Electrolysis of dilute Sodium Chloride Solution, NaCl
Between sulphate ions
and hydroxide ions,
which will be discharged?
Between Sodium ions
and Hydrogen ions,
which will be
*instead of sulphate ions
*instead of sodium ions
