There is a beaker with 0.4% sucrose solution and the solute potential is -4. Inside the beaker, there is a dialysis bag with 01% sucrose solution, solute potential -1 and pressure potential 0. When the beaker is open to the atmosphere, what is the pressure potential of the system?

Answer 1

well, since water potential is pressure + solute concentration, that means that it would be the sum of the beaker AND the dialysis tubing. so. -4 + -1 is -5. Should be the answer. :P
