Answer: Option (c) is the correct answer.
Step-by-step explanation:
Electrical conductivity of a solution is the ability of flow of current through the solution.
Some factors on which electrical conductivity depends are as follows.
More is the concentration of ions into the solution more will be the flow of current.
More ionic character means more number of ions into the solution. Hence, more is the flow of current.
Potential number also affects electrical conductivity. Whereas type of solvent that is whether a solvent is polar or non-polar will also affect electrical conductivity.
But size of container does not affects the electrical conductivity of a substance.
Hence, we can conclude that size of container is the choice which is not a factor in the amount of electrical conductivity of a solution.
