Sucrose Concentration Lab Report

The results of this experiment show that as the sucrose concentration of the potatoes increases, the potato appearance, shape, and flexibility increase. The qualitative observations show the flexibility of each potato before and after the incubation. The initial observations for the potato slivers were slightly stiff and high in flexibility. After leaving the 10 mL sucrose concentration solution for 45 minutes, the results show an increase in appearance, and flexibility of each individual potato. The qualitative observations from the initial results show that the potato cells have a flavescent colour with rigid texture. Also, the observations for the final results shows that the colour of the potato slivers were cream. The potato at the sucrose concentration 0.0 M becomes stiffer and harder in flexibility than its initial results. …show more content…
The concentration of sucrose at 0.3 M and 0.4 M, flexibility increased dramatically. Also, the potato at 0.5 M sucrose concentration increased in flexibility; but, the potato decreased in size. Furthermore, the quantitative observations show the effect of sucrose concentrations on mass. The mass changes in grams ranges from 0.53 g to -0.32 g, resulting in the decrease in values as the concentration increases. In fact, the concentrations of 0.0 M, 0.1 M, 0.4 3, and 0.4 M had a positive value for the change in mass (g), while the concentrations 0.2 M and 0.5 M had a negative value. In addition, the percent change in mass ranges from 35.09% to -22.69%. Also, the graph shows the percent change in mass versus the sucrose concentration in molar, as shown in Figure 1. In addition, the trend on the graph shows the increase in concentration leads to the decrease in the

    The goal of this lab was to find the molar sucrose concentration at equilibrium. Which is when the potato core and the sucrose solution reach equilibrium, so that no water is entering or leaving the cell. After collecting the data, the line of best fit never crossed the x-axis or showed where the molar sucrose concentration at equilibrium. I had to extrapolated the point at which it crossed the x-axis. This led to the data being unreliable because there is no physical evidence present that shows…

    2401.51501 Instructor Beverly Mitchell October 18, 2015 Abstract This lab will be focused on the movement of water from an area of low to high concentration via osmosis (McKinley, O’Loughlin, & Bidle, 2015). This experiment will be tested on eggs that have had their shells removed and we will see how a couple of solutions of different concentrations will affect the membranes on the eggs. One egg will be placed in 30% sucrose solution and the other in distilled water. The purpose of this experiment…

    Doherty Biology Lab Report 09/29/16 The change in concentration of sucrose affect the change in mass of potatoes cores. Introduction This experiment was focus about osmosis. If solute cannot readily move across the membrane, water will move and tend to balance the solute concentration. In this process, called osmosis, water moves across a membrane from the hypotonic compartment (with a lower concentration) into the hypertonic compartment (with a higher concentration). In hypotonic solution…
