To remove the most salt from the mixture of albumin solution and starch solutions in the dialyzing bag, the best action would be to replace the water with fresh distilled water periodically.

Explanation:
Dialysis is a process used to remove small solute particles from a solution by allowing them to pass through a selectively permeable membrane. In this case, the dialyzing bag acts as the selectively permeable membrane.

When the dialyzing bag is immersed in distilled water, the water molecules will move across the membrane from a region of lower solute concentration (outside the bag) to a region of higher solute concentration (inside the bag). This movement of water will help in diluting and removing the salt particles from the mixture.

However, as the concentration of salt inside the dialyzing bag decreases, the driving force for the movement of water across the membrane will also decrease. To maintain a continuous removal of salt, it is necessary to replace the water with fresh distilled water periodically. This will ensure that the concentration gradient across the dialyzing bag remains high, allowing for effective removal of salt from the mixture.

Leaving the dialyzing bag in the distilled water for an extended period of time without replacing the water will eventually lead to equilibrium, where the concentration of salt inside and outside the dialyzing bag becomes equal. At this point, there will be no net movement of salt, and thus, the removal of salt from the mixture will slow down.

Replacing the dialyzing bag periodically can help in preventing clogging or buildup on the membrane, but it will not have a significant impact on removing salt from the mixture. The key factor in removing salt is to maintain a high concentration gradient across the dialyzing bag, which can be achieved by replacing the water with fresh distilled water periodically.
