Question

When a concentrated solution of an electrolyte is diluted?
A.Its specific conductance increases
B.Its equivalent conductance decreases
C.Its specific conductance decreases and equivalent conductance increases
D.Both specific and equivalent conductance increase

Answer 1

Hint: As we know that the electrolysis process contains electricity. The electricity will break down the electrolytes and there is a formation of elements. The electrolyte is a gel or it is a liquid consisting of ions and that can be decomposed by using electrolysis. Which means, the substance or compound will be dissociated into ions and it gains the capacity to pass electricity. Potassium, sodium, calcium, phosphate, chloride etc are the examples of electrolytes.

Complete answer:
When a concentrated solution of an electrolyte is diluted, its specific conductance will not increase. Hence, option (A) is incorrect.
When a concentrated solution of an electrolyte is diluted, its equivalent conductance will not decrease. Hence, option (B) is incorrect.
When a concentrated solution of an electrolyte is diluted, its specific conductance decreases and equivalent conductance increases. The specific conductance is also known as conductivity. The specific conductance is defined as the capacity to conduct the electricity. And the equivalent conductance is equal to the conductance of a volume of a solution present in one equivalent weight of substance dissolved which occurs between two parallel electrodes. And the specific conductance decreases with concentration of electrolyte and the equivalent conductance increases with concentration of electrolyte. Hence, option (C) is correct.
When a concentrated solution of an electrolyte is diluted, its specific conductance will not increase. Hence, option (D) is incorrect.

Hence, option (C) is correct.

Note:
The specific conductance is inversely proportional to the concentration of electrolyte and its equivalent conductance is directly proportional to the concentration of electrolyte. Because, specific conductance decreases with concentration of electrolyte and the equivalent conductance increases with concentration of electrolyte.
