What is the degree of dissociation of the electrolyte if 60 of every 200 of its molecules decay into ions?
July 28, 2021 | education|
Electrolytic dissociation is the process of decomposition of an electrolyte into ions under the action of a solvent.
The characteristic of ED is the degree of ED. Denoted by a.
a = N / N0 ∙ 100%
N – the number of molecules decayed into ions
N0 is the total number of molecules of the solute.
0 <a <1.
a = 100% * 60/200 = 30%.
a> 30% – strong electrolyte,
2% <a <30% – average,
a <2% – weak.
Factors affecting the degree of ED:
3) the nature of the electrolyte and solvent,
4) dissociation constant.
