The purpose of this experiment was to investigate how different sucrose concentration affects the rate of osmosis on potato cubes. This was done using potato cubes cut to exactly the same size (2cm) long 1cm wide and 1cm high. And applying them in glasses filled with different concentrations of sucrose solution. 0.0% 0.2% 0.4% 0.6% 0.8% and finally 1.0%. Say no to plagiarism.

The time it took to soak the potato cubes was 40 minutes. Hypothesis: The results predicted that if potato cubes were placed in a concentration of sucrose where the water potential was higher than the water potential of the potato itself, this would cause the mass of potatoes to increase and if they had a similar water potential there would be no will be no change in mass, and finally if the water potential of sucrose is less than the water potential of potato it means that the mass of potato will decrease Background: Osmosis is the movement of water molecules. Water molecules move from a higher water potential to a lower water potential across a semipermeable membrane. There are a few factors that influence the rate of osmosis, including particle size and temperature, however the factor that is being studied today is the concentration of sucrose. As the concentration of sucrose increases, the mass of the potato also increases because it has been placed in a hypertonic environment. solution, which means it has a larger amount of particles dissolved in the solution. Variables-Independent Variables - The concentration of the sucrose solution in which the potato cubes were placed. 0.0%, 0.2% 0.4% 0.6% 0.8% 1.0% Dependent variables - `: The change in mass of potato cubes before and after the experiment Ratios: Be able to balance the different surface-to-volume ratio to limit the effect on the osmosis rate the dimensions should first be measured using a ruler keep the same diameter for each potato cuboid Tissue type - Tissue type has a very large effect on the osmosis rate osmosis because the amount of glucose in each tissue type is different. This can be controlled by using only one type of fabric, meaning you use the same potato to create the 6 cuboids. Materials used 1 large potato (cut into 6 cuboids) White ruler Beakers 6xElectric scale Sucrose (0.0 , 0.2, 0.4 ,0.6 , 0.8 , 1.0 ) Filter paper 6xKnifeStopwatch/timer ProcedureLab coats were worn at the start of the experiment. Risk assessment was filled out .6x filter paper was labeled (sucrose concentration, weight of potato before and after) Potato was peeled using knife Potato peel (waste) was placed in a plastic container labeled as waste 6 cuboids were cut using a ruler and the same potato. Each cuboid was measured to measure 2cm x 1cm x 1cm. Any other waste was disposed of The electric scale was plugged in The scale was then switched on The scale was set to grams Next the labeled filter paper was placed on the scale The scale was set to 0 before there was even placed on top of a piece of potato to measure the mass This was repeated 6 times for each cuboid Then all the cuboids were placed in sucrose, 1 cuboid in each glass The cuboids were left to soak for 40 minutes The cuboids were then
