How does the rate of pH affect osmosis?

Answer 1

the greater the pH of a solution, the more acidic (concentrated) it becomes.
the greater the concentration gradient of a substance on either side of a membrane the faster the molecules tend to diffuse.

so, if a concentrated solution were to be placed in a semi-permeable dialysis visking tubing (only filled halfway), and placed in a testube of water, it will be noticed after a considerable amount of time, that the tubing becomes firm distended by the solution inside.
so, u see rate of pH affects the concentration of the solution which in turn affects osmosis.
in other words, the rate of pH indirectly affects osmosis.

Answer 2

pH effects osmosis by increasing or decreasing the available solutes that are able to permeate the membrane.

If you have a have a basic protein, for example, and you raise the pH, then you will free all the NH groups and make them less water soluble - less hydrophilic. You should then expect to get more of the water in your solution to permeate through the membrane and out of your solution.

Answer 3

In biology, extreme pH changes decrease the solubility of cellular proteins to the extent that they precipitate into a formless soup. This would destroy both cell structure and function. Living systems must therefore avoid pH fluctuations of their intra- and
intercellular fluids. This is a formidable task when one considers the great array of acids and bases that are assimilated by living systems, not to mention the acidic and basic byproducts of
cellular metabolism. pH can be maintained within a constant range in living systems due to buffers.
