Question

what are the factors affecting the value of degree of ionisation? Explain in detail.....​

Answer 1

Explanation:

Factors affecting Degree of Ionisation

(i) At normal dilution, value of is nearly 1 for strong electrolytes, while it is very less than 1 for weak electrolytes. (ii) Higher the dielectric constant of a solvent more is its ionising power. Water is the most powerful ionising solvent as its dielectric constant is highest

Answer 2

QUESTION⤵

what are the factors affecting the value of degree of ionization? explain in detail.....

ANSWER⤵

(1.) Temperature↔ on temperature increase, ionization increases and then alpha also increases. (because dissociation is endothermic reaction).

(2.) Dilution↔On Dilution increase, alpha also increases.

(3.) Nature of electrolyte↔

(i.) Strong electrolyte::- alpha is 100%

(ii.) Weak electrolyte::- alpha is smaller than 100%

(4.) Nature of solvent↔ If dielectric constant(mu) of solvent increases then the value of alpha increases.

(5.) Mixing of ions↔

(a.) Common ion effect

(b.) odd ion effect.
