Answer:
The concentrations of KCl and NaCl will tend to be equilibrated in both sides, until there is no more movement in any direction.
Explanation:
Since this is an artificial membrane, the concentration of both substances in both sides, will tend to be the same, this is just the answer to a physical distribution of the concentration of the substances.
In natural membranes, this is not like this because all the living things need to have a movement of these minerals to activate the electric response, this happened by the action and help of some carriers because is an active process, that means, need energy and some other carriers to move the compounds from one side to another.
