Were told that six identical potato core cubes were isolated from a potato the initial weight of each cube was recorded each cube was then placed in one of six open beakers each containing a different sucrose solution the cubes remained in the beakers for 24 hours at a constant temperature of 23 degrees Celsius after 24 hours the cubes were removed from the beakers blotted and re weighed the percent change in mass due to a net gain or loss of water. Osmosis is the movement of water through a semi-permeable membrane from a region of high concentration to a region of low concentration tending to equalise the concentrations of the water. Osmosis is passive transport meaning it does not require energy to be applied.

Since youre waiting for rescue and are a top notch AP Biology student you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not. The majority of dissolved ions in seawater is NaCl roughly a 05M concentration. The ionization constant of NaCl is 20.

In this video Paul Andersen defines water potential and explains how it can be calculated in a simple system. He explains how water can moved through osmosi. There are several reasons that this substance is added during treatment.

The first one is to remove salt from the water. Its one of those problems where a sucrose solution is put in a dialysis bag then the bag is put into a beaker with a different solute solution. We have to calculate the water potential and determine which way the water will move.

The dialysis bag has a water potential of 9806 bars and the beaker has a water potential of 12257 bars. Water potential and osmosis worksheet 1. Additional water potential practice problems.
