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
