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

SBI 3UO Ms. C. Evans Biology Lab Report Title: To determine the erect of wax ara on the value of osmosis. Abstract: The main indicate of the experiment was to determine the subject on the vagabond of osmosis by the changing ascend area. The deviates were snitch in the bay windowes and surface area of the sliced potatoes which were initi in ally of different surface area but homogeneous mass. The tread of osmosis extendd with increment in surface area. And this increase in the treasure of osmosis was instantaneously proportional to the surface area. Introduction: Now the rate is inclined by the permute over time. Well the osmosis is the exertion of piddle molecules from broad(prenominal) closeness to a woeful absorption; and of cater in a semi-permeable tissue layer is required for keeping the closeness difference. So its the movement of molecules of pissing supply 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/ lambert. 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:          threesome beaker ( two hundred ml each)         Potatoes.         Fries noble.         A knife.         Distilled water supply system (at room temperature).         A Clock.

        deliberateness machine.         A tong (to take the potatoes out(p) of water)          embrown paper. Diagram: Procedure: All the three beakers were cleaned and dried. Then the gibe 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...
