Is dialysis possible using whatman filter paper?

No, dialysis is typically performed using a specialized dialysis membrane that allows for the separation of molecules based on size. Whatman filter paper is not designed for dialysis as it lacks the necessary properties to effectively separate molecules based on size through the process of diffusion.


Why does the water passes through the filter paper but not the cornstarch?

Basically because the pores in coffee filter are big enough to let water molecules through, while coffee grinds are too large to pass. An in case anyone wonders why the water passes through the filter - that's gravity ;) because the coffee is a greater thickness and water is not thick at all...water can fit into anything it wants to....you dont filter water anyway, you filter the items in it Is it not somethimg to do with particles????????? we do not filter water it is clean we filter the items in it!!!!!!! we have tofilter it if it is a solution

What do you need to know about filter in order to predict which molecules can pass through?

To predict which molecules can pass through a filter, you need to know the pore size of the filter. Smaller molecules can pass through filters with larger pore sizes, while larger molecules may be blocked. Additionally, the filter material and its properties, such as charge and hydrophobicity, can also influence which molecules can pass through.
