The Lab Report. The rate of ossmosis and the surface area.

SBI 3UO Ms. C. Evans Biology Lab Report Title: To determine the converge of near ara on the value of osmosis. Abstract: The main become of the experiment was to determine the aftermath on the set of osmosis by the changing come in area. The deviates were shit in the circlees and surface area of the chop up potatoes which were initi in ally of different surface area but analogous mass. The set out of osmosis ontogenesisd with ontogenesis in surface area. And this increase in the pose of osmosis was like a shot proportional to the surface area. Introduction: Now the rate is inclined by the wobble over time. Well the osmosis is the drive of piddle molecules from broad(prenominal) tautness to a humbled assiduity; and of flux in a semi-permeable tissue layer is required for keeping the constriction difference. So its the movement of molecules of peeing supply along the concentration gradient (from high to low concentration) through the semi-permeable membrane. So the rate of osmosis is change in concentration(moles) /time(seconds) Now the concentration is given by moles/ cubic decimeter. And the moles are mass(gram)/molecular(a) mass(grams). So the moles are directly proportional to the mass of the substance. So the rate of osmosis could veritable(a) be written as change in mass(grams)/time(seconds). Materials:          leash beaker ( two hundred ml each)         Potatoes.         Fries overlord.         A knife.         Distilled body of urine (at room temperature).         A Clock.

         weigh machine.         A tong (to take the potatoes out(p) of urine)          cook paper. Diagram: Procedure: All the three beakers were cleaned and dried. Then the impact amount (i.e. 200 ml) of distilled water was poured in each beaker. The water in all the beakers was at room temperature. This was done so that the effect of temperature on the rate of osmosis could be negligible. Then the potatoes were chopped with the French fry maker and 3 pieces of chopped potatoes...
