How does equivalent conductance vary with concentration?
How does equivalent conductance vary with concentration?
While the specific conductance of a solution increases with concentration, the equivalent conductance decreases as the concentration increases. Onsager showed theoretically for strong electrolytes in dilute solution that the effect of ionic attraction reduces the equivalent conductance.
How does equivalent conductance vary with temperature?
Ans: Specific conductance of a solution depends on absolute temperature. It increases with increases in temperature due to a decreases in ionic friction co- efficient. Ans: Equivalent conductance is the conductance of a solution containing one equivalent of the electrolyte.
How does conductance vary with concentration and temperature?
Specific conductance (k↑) increase as concentration increases because per ml no. of ions increases. The conductivity of all electrolytes increases with increase in temperature. Also, Equivalent conductance decrease with increase in concentration because of decrease in ionic mobility.
Does equivalent conductance depend on concentration?
Equivalent conductance increases as concentration decreases.
What is equivalent conductance?
The equivalent conductance of an electrolyte is defined as the conductance of a volume of solution containing one equivalent weight of dissolved substance when placed between two parallel electrodes 1 cm apart, and large enough to contain between them all of the solution.
What is the formula of equivalent conductance?
Answer: The term ‘equivalent conductance’ can be defined as the net conductance of every ion that is produced from one gram equivalent of a given substance. V = Volume (in millilitres) that contains one gram equivalent of the given electrolyte.
Does conductance increases with concentration?
Molar conductance is dependent on the concentration of the electrolyte. When the solution is dilute the number of ions available per unit volume reduces, resulting in the reduction of the conductivity. These active ions impart more conductivity. …
What is equivalent conductance in chemistry?
How does equivalent conductance vary with dilution?
The equivalent conductance of strong electrolyte is increased by dilution, because its value is equal to the multiple of Kυ and the volume of solution. By making dilution the volume of solution increases which also increase the value of equivalent conductivity.
How does specific conductance decreases and equivalent conductance increases with dilution?
(i) Specific conductance decreases with dilution whereas equivalent conductance increases with dilution. When the solution is diluted the number of ions present in 1cm3 of solution decrease and as a result specific conductance decreases.
How do you write equivalent conductance?
Denoted by ᴧe. Equivalent Conductance(ᴧe) is calculated from specific conductance.
What is formula of equivalent conductance?
Equivalent conductance is defined as the conductance of all the ions produced by one gram equivalent of an electrolyte in a given solution. Equivalent conductance λ = k × V Where V is the volume in mL containing 1 g equivalent of the electrolyte.
