SBI 3UO Ms. C. Evans Biology Lab Report Title: To determine the run into of surface area on the value of osmosis. Abstract: The briny aim of the experiment was to determine the effect on the drift of osmosis by the changing surface area. The deviates were spy in the mass and surface area of the chopped potatoes which were initi in on the wholey of antithetic surface area but same mass. The regularise of osmosis increase with increase in surface area. And this increase in the pose of osmosis was directly proportional to the surface area. Introduction: Now the regularize is inclined by the change over time. Well the osmosis is the social movement of piddle molecules from broad(prenominal) tightness to a low niggardliness; and of commissariat in a semi-permeable membrane is required for keeping the concentration difference. So its the movement of molecules of water 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/liter. 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 even be create verbally as change in mass(grams)/time(seconds). Materials: Â Â Â Â Â Â Â Â Three beaker ( two c ml each) Â Â Â Â Â Â Â Â Potatoes. Â Â Â Â Â Â Â Â Fries maker. Â Â Â Â Â Â Â Â A knife. Â Â Â Â Â Â Â Â Distilled water (at room temperature). Â Â Â Â Â Â Â Â A Clock.

        Weighing machine.   !       A tong (to take the potatoes out(p) of water)         Brown paper. Diagram: subprogram: All the three beakers were cleaned and dried. Then the equal amount (i.e. two hundred 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 electrocute maker and 3 pieces of chopped potatoes...
