Brown Sugar Solubility

Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water.

of sugar to 25ml of water and dissolve it. When we have the water at

My hypothesis is that if I add different amounts of sugar to the same amount of boiling water and allow it to be cooled, than the one with the additional cup of sugar will be the one that grows more crystals. I determined that my hypothesis was correct. The glass I chose to add the pure cane sugar did grow much more crystals at a

Our testable question was, what is the effect of different liquids on the dissolving rate of the alka seltzer. To answer this question we dissolved alka seltzer in three different liquids, and recorded the data we found. After testing water three times

In this lab we tested how changing the content of the water affects the speed of the alka seltzer dissolving. My hypothesis was that the tap water would dissolve the tablet fastest, the salt water would be second fastest, and the sugar water would be the slowest. I was correct that the tap water would dissolve the fastest, but I was wrong in that the salt water would dissolve faster than the sugar water. I think that our results came out the way they did because of the amount of sugar and salt we put into the water. When we put the sugar and salt into the beakers, we came up with those measurements on the spot. After the salt and sugar had been added, the salt water was very cloudy, but you could barely tell the tap water from the sugar water.

1. Why is it important to use distilled water instead of tap water used in Part 1?

We know that water will move through a membrane from more free water to less free water. The higher the solute concentration is, the less free water there is. All of the sucrose solutions are being put in pure water, but the ones with the most sucrose will need the most water to diffuse inside and bring the free water levels to equilibrium, and the ones with less will need less water to diffuse.

of a membrane. The lab also shows how the semi permeable membrane works; it allows only certain molecules to pass through it, while others aren’t allowed through it. The lab shows this because according to my results the semi permeable membrane in the gummy bear allowed more water molecules to pass through it, while the semi permeable membrane didn’t let other solution molecules resulting in the water to have more weight while the other two solutions grew less in weight. The lab also demonstrates that the solutions with more sugar will gain less in weight. This is because the solution already has a higher concentration inside it, so less of the solution will go inside the gummy bear. According to my results the water is a hypotonic solution, while the Orange Switch and Gatoraid would also be a hypotonic solution due to the fact that all he gummy bears gained mass. If it were to be a isotonic solution the gummy bear would need to stay the same mass. If any of the solution would be a hypertonic solution the gummy bear would to shrink in

These are refined sugars commonly added to food, beverages and pastries by consumers, cooks and manufacturers. It may also be found in natural sources like syrups, honey, fruit juices and fruit juice concentrates.

Our purpose in this lab was to create four solutions of the same components and different concentration. I found the concentration in Molarity (mol/liter). I would dilute a solution to create new solutions, using the formula M1xV1=M2xV2 where M=molarity and V=volume. In this lab, there were four solutions, Solution A, Solution B, Solution C, and Solution D. The solute or substance that dissolves was sugar and the solvent or substance that the solute dissolves in was water. For Solution A, I weighed 3.42 g sugar and diluted to 100 mL to get a concentration of 0.10 M and the color of bright red. For Solution B, I weighed 0.342 g sugar and diluted to 100 mL to get a concentration of 0.010 M and the color of pink. For Solution C, I measured 10

Though the theory following the hypothesis is correct and the experiment was carried out with as much attention as possible in a high school laboratory, the results obtained were still indicative of a few errors and did not support the predicted hypothesis. From the results obtained it can be concluded that as the concentration of sucrose increases the average percentage change in mass decreases. This is because the salt concentration inside the potato cubes of 10%, 15% and 20% concentration is less that in the salt concentration on the sucrose solution, thus the three cubes submerged in the 10% - 20% concentrated solution lost mass (hypertonic). However the cube submerged

There were several steps completed to prepare for the experiment. Three dialysis tubes were filled with approximately the same volume of distilled water and then were tied shut. The initial mass (in grams) of the tubes was taken using a triple beam scale. I then filled three 500 mL beakers with 400 mL of water each and dissolved different masses of solute (table sugar) in each beaker in order to make 5%, 10%, and 20% solutions. The beakers were labeled accordingly, and then 20 g, 40 g, and 80 g (respectively) of table sugar was weighed out using a digital scale and placed into the corresponding beakers. The sugar was stirred in using a stirring rod until all of the solute was completely dissolved.

As the sugary syrup is forced out of the hole, they form sugar threads that are about 50 micrometer in diameter. The thread is so fine that they solidify immediately. Because the sugar thread cools immediately upon exposing to open air, the sucrose molecules do not have enough time to regroup. The threads are not sugar crystals but are thousand strands of sugar glass, which is sucrose molecules that solidify without structure. However, if the cotton candy absorb moisture from the surrounding, the water will travel along the fiber of cotton candy, At some point, each droplet of water becomes saturated and that's why the cotton candy will become

The purpose of this experiment is to conduct what happens to gummy bears when we put them into different liquids. When we were done we gathered data and saw that the gummy bears ended up with different textures and sizes. There were only some minor differences. For water after a day, the length changed, the width, height, and mass. For salt water only the mass changed, before it was 2.6 and after it was 1.5 grams. The next liquid is sugar water, and for that liquid all the of the data changed. The length was 3 cm before, after it was 3.5 cm. The width of the gummy bear was 3 cm before, after it was 1 cm, and after it was 1.5 The height was 2 cm, and changed to 1 cm. Lastly is the mass, it was 2.6 and the after it changed to 5.1. The

The independent variable of this experiment were the different types of the solutions used, while the dependent variable was the mass of the cucumber slices. The constants were, the amount of liquid used and the time the cucumbers were left in the solution. While the control was the cucumber left in the cup with no solution. The students made a hypothesis saying that they believe that the cucumber slices put into the salt solution would decrease in mass while the cucumber put in the distilled water would increase in mass. In the end, the results of the experiment supported the students
