Which one of the following aqueous solutions would you expect to have the smallest conductance: _______
(a) 0. 060 m nacl,
(b) 0. 030 m nacl, or
(c) 0. 015 m nacl? explain your reasoning

Respuesta :

(c) 0. 015 m NaCl of the following aqueous solutions would be expected to have the smallest conductance.

Conductance is the expression of the ease of the passing of the electrons. Conductivity is a numerical expression of the tendency of an aqueous solution to carry an electric current. Electricity is conducted through an electrolytic solution due to the movement of ions. In general, the greater the number of ions in the solution higher is the conductance.

The conductance of a solution depends on 1) the concentration of the ions it contains, 2) on the number of charges carried by each ion, and 3) on the mobilities of these ions.

In an aqueous solution , charged particles that conduct electricity are ions , because of free ions electricity can be conducted in the solution. So , conductance depend upon concentration of the solution , more the concentration of solution more will be the conductance .

out of given solution , options a) 0.060 m solution of NaCl will be the most conducting solution as it is most concentrated option c) 0.015 m solution of NaCl  will be the least conducting solution as it is the least concentrated solution .

correct option will be (c) 0. 015 m NaCl of the following aqueous solutions would be expected to have the smallest conductance.
