The wastewater solution from a factory containing high levels ofsalts needs to be diluted before it can be released into theenvironment. Therefore, two containers of waste solution areseparated by a semipermeable membrane and pressure is applied toone container, forcing only water molecules through the membraneand diluting the waste solution in the other container. As dilutioncontinues, higher and higher pressures are needed to counteract thenatural tendency for the water molecules to have a net flow backtoward the more concentrated solution.
What was the applied pressure at the end of this process if thefinal concentrations of the solutions were 0.051 M and 0.120 M at atemperature of 23 C?
answer in atm
There are limitations to the amount of pressure that can be appliedduring reverse osmosis because of the physical nature of themembrane. A membrane has been developed that can withstand osmoticpressures,II , of up to 1.52Ã10^5 torr . Calculate the maximummolar concentration of a solution that can be purified by reverseosmosis using this membrane at 25 C.
