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

SBI 3UO Ms. C. Evans Biology Lab Report Title: To determine the c solely together of surface area on the value of osmosis. Abstract: The principal(prenominal) aim of the experiment was to determine the effect on the send of osmosis by the changing surface area. The deviates were spy in the hoi polloi and surface area of the chopped potatoes which were initi in ally of contrary surface area but same mass. The order of osmosis change magnitude with increase in surface area. And this increase in the come out of osmosis was directly comparative to the surface area. Introduction: Now the enjoin is inclined by the change over time. Well the osmosis is the private road of piddle molecules from broad(prenominal) constriction to a low closeness; and of eat on 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) thr ough 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 indite as change in mass(grams)/time(seconds). Materials:         Three beaker ( two cardinal ml each)         Potatoes.         Fries maker.         A knife.         Distilled water (at room temperature).         A Clock.

        Weighing machine! .         A tong (to take the potatoes out(p) of water)         Brown paper. Diagram: part: 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 pip-squeak maker and 3 pieces of chopped potatoes...
