The majority of dissolved ions in seawater is nacl roughly a 0 5m nacl concentration. If a cell s ψ p 3 bars and its ψ s 4 5 bars what is the resulting ψ. Ap biology ap biology water potential problems name reminders. A cell is in equilibrium with its environment.

If there are no units. The ionization constant of nacl is 2 0. Since you re waiting for rescue you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not. In which direction will the net flow of water be.

The solute potential of the cell s cytoplasm is 0 45mpa. The water potential of the surrounding solution is 0 32mpa. Your own cells have a 0 15m nacl. The original cell from question 1 is placed in a beaker of sugar water with ψ s.

When the cell was first put into the solution it was flaccid. Subjects discussed include osmosis hypertonic solutions isotonic solutions hypotonic solutions and wat. Units of water potential pressure potential and solute potential are typically bars megapascals or kilopascals. An introduction to osmolarity and water potential.
