The Rate of Diffusion and Osmosis of Various Solut Essay

ions With Distilled Wateras an Ambient Environment
Throughout the process of the experiment, various concentrations of a
solution of Sucrose and Water were placed into hydrolysis tubing and placed
into and ambient environment of sterile water. An observation of a Starch
solution in an ambient solution of sterile water and iodine was done to
check for a chemical reaction of starch and iodine indicating diffusion.

Also an observation of two segments of carrot placed each in Distilled and
in Salt Water, to determine whether or not osmosis is taking place…



“In an attempt to satisfy my hypophysis that when one placed a set
amount of various molar concentrations of a solution of sucrose and
distilled water into an ambient solution of distilled water, diffusion into
the hydrolysis tubing with the solutions will occur, causing the tubes to
gain weight. Also that a solution of starch and water in hydrolysis tubing
placed in a Water/Iodine solution would generate a chemical reacion within
the tube between the starch and the iodine, also indicating diffusion. And
lastly that two pieces of carrot, one placed in water, the other in salt
water, would reveal that the salt water would draw moisture out of the
carrot into the salty environment, causing the carrot in the salt water to
become limp the opposite would occur in the other carrot.” Throughout the
process of the experiment, various concentrations of a solution of Sucrose
and Water were placed into hydrolysis tubing which in turn are placed into
and ambient environment of sterile water. Also, an observation of a Starch
solution in an ambient solution of sterile water and iodine was done to
check for a chemical reaction between the starch and iodine indicating
diffusion. Last, an observation of two segments of carrot placed one each
in Distilled and in Salt Water, was done to determine whether or not
osmosis is taking place between the carrots and the solution or the
solution and the carrots.

Materials Required
.Four 5″ lengths of hydrolysis tubing
.Two segments of carrot, sliced lengthways and about 3″ long
.Four Small cups, labeled Starch, 1M, .4M and H2O
.Iodine
.Pipette or eyedropper
.Scales measuring grams
.about 5oz of each solution> 1M sucrose/water, .4M sucrose/water,
distilled water, 50% starch/water
.Two 30 minute Timers
.Two 20oz Open Beakers with one filled with Distilled Water, and the
other Salt Water(about 15oz)
.Rubber bands or string to tie off tubing
Procedure
.First, 2 lengths of carrot, cut down the middle length-ways, are
placed one each in a beaker of distilled water and the other in salt
water and allowed to set.

.In the first experiment, 3 lengths of hydrolysis tubing with one end
tied off securely, approximately 5 inches long, were filled each with
one of 3 solutions, distilled water, .4M solution of sucrose and
water, and 1M solution of sucrose and water.

.Then all air in the tube was removed, and the other end was tied off
securely.

.3 Small cups were then filled with distilled water and labeled with
one of the 3 solutions mentioned earlier.

.Then tubing with the solutions inside are then dried completely and
all excess solutions cleaned off from the exterior.

.The weights of the tubes in grams was then recorded and the tubes are
placed in their respective cups of sterile water and allowed to set
for thirty(30) minutes.

.While the first observation is setting, another 5 inch length of
hydrolysis tubing is tied off at one end and fill with 10-15ml of a
50% solution of Starch and distilled water.

.The air is removed from the tube, and the other end is tied off
securely, and all excess starch is removed from the exterior of the
bag to prevent the occurrence of starch in the ambient solution,
giving the appearance of diffusion into the ambient solution.

.Another cup is filled with distilled water, and approximately 15
drops of pure iodine is added.

.The tube with the starch solution should be placed into the cup
filled with iodine solution and allowed to set for 30 minutes.

.Next, while both solution sets are setting, an observation was made
of the carrot pieces that were placed into the beakers earlier.

.The primary objective of this observation being to determine which,
if either, of the carrot pieces was subjected to osmosis, and to
