Slime Design Lab:
Investigate how you can vary the properties of slime

 This report will investigate if and how the concentration of sodium borate affects the viscosity of a sample of slime.

Background Information:
…show more content…
If there were an increased volume of poly ethenol the slime would most likely be thicker. This is because it would be able to make a longer chain and expand.
The same volume of poly ethenol was used throughout the experiment.
Volume of the sodium borate

The volume of the sodium borate may have also affected the viscosity of the slime. The more sodium borate the thicker the slime because this would also lengthen the chain and cause the slime to expand.
The same volume of sodium borate was used throughout the experiment.
Temperature of the poly ethenol
Under pressure slime expands and becomes thicker. Perhaps it too, expands and thickens when under heat.
The temperature of the polyethenol and sodium borate solution was kept constant by completing the procedure on the same day at room temperature.
Temperature of the sodium borate

The same marble

It is important to use the same marble because this is what determines the viscosity of the slime. If the marble increased in mass, then it would hit the bottom of the beaker faster altering the overall results.
The same marble was used through out the

This is important because the slime is dilatant, which means that under pressure it will expand and thicken. If the slime was kneaded longer than another slime sample it could have caused it to be thicker altering the overall results. This is a significant weakness.
In future experiments time the kneading process and keep it at a constant time throughout the experiment. For example kneading the slime for only one minute.
Systematic error: When adding water to dilute the sodium borate solution, the formula produced very precise numbers to two decimal places. These were impossible to measure accurately on a 50 cm3 measuring cylinder. This is an insignificant weakness.
In future experiments providing more precise equipment. For example using a 1 cm3-measuring cylinder, which has markings of decimal places. Or simply being provided with 5 different concentrations of the sodium borate solution, so there would be less chance of error or weakness in general.
Systematic error: It was difficult to see when the marble had reached the bottom of the beaker. This is an insignificant

    Results/Discussion: 2-butanol and Acetic Acid were refluxed together with anti-bumping granules and a catalyst of sulphuric acid for 1 hour and five minutes. Anti-bumping granules are small ceramic granules which have rough edges. They are added within a mixture to encourage smooth boiling. In this experiment by adding the anti-bumping granules we were able to achieve smooth boiling throughout both the reflux process and the distillation process. Without adding these granules, bubbles of vapour may be difficult to form due to both process being conducted in a very clean, smooth glassware.…

    In the experiment the results showed how the reaction time of a reaction can be affected by different variables like temperature and quantity. The hypothesis of the experiment was that Sodium thiosulfate would be the agent that affects the time of the reaction. This was proven partially since the data from figure 3 and figure 1 shows that the higher concentration of Sodium thiosulfate causes the solution to take longer to occur therefore supporting the hypothesis. Data from figure 3 also shows that increasing KI in the solution causes the reaction time to occur faster. The data from figure 2 show that temperature also factors into the time it takes for the color change to occur.…

    Heating up the solvent gives the molecules more kinetic energy. The faster motion means that the solvent molecules collide with the solute with a higher frequency and the collisions occur with more force. Both components help to increase the rate at which the solute dissolves. A change of temperature does not only affect the rate of dissolving, but it also affects the amount of solute that…

    Introduction: Solubility is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly you first of all need to add boiling water to dissolve the sugar crystals and make sure they have completely dissolved before adding cold water to increase the amount, this is an example of the effect of temperature on solubility of sugar. The rate of solubility can depend on multiple factors such as the temperature of solvent, the size of the solute and how the solvent is stirred for example stirring time, big or small movements.…

    Although I didnt predict that the beaker would be the most accurate, I thought it would be the most precise. The flask being the most accurate was out of the question because the flask doesnt start measuring until 10mL, therefore small volumes would not be measured accurately.In addition, I saw the beaker and flask as glassware to simply hold chemicals, so having the beaker be the most accurate was…

    The membrane will also be more fluid at the higher temperature, making it easier for the solution to move across it quickly. The results from each experiment supported my hypothesis. As seen in the graphs, both the solution with the 100mM of KMnO4 and the solution placed in the water at 48˚C diffused quicker than any of the other solutions.…

    Group five got a result of 99%, which was significantly lower than the other results for that category; the other results were 117%, 114%, 120%, 116%, and 115%. This error could have happened due to the dialysis bags not being tied tight enough. If given the chance to redo the experiment, I would probably re-examine and ensure that the dialysis bags were tied correctly and had the right amount of solution in each of them. I would also ensure that all of the bags were dried and weighed correctly. If we were to expand the experiment, I would suggest using more solutions, different than the ones we already used and also possibly leave the solution filled bags in the water longer, to see if that would have any effects.…

    Silica shall be used to ensure that the water does not coalesce and thus remain in tiny droplets. This shall serve to increase the surface area of water that comes into contact with the methane gas, thus speeding up the rate of absorption of the gas. The “dry water” soaks up the gas quickly at the water’s normal freezing point; instead of having to go to the -113 degrees Celsius (or be under a pressure of up to 5000 kilopascals) required to maintain the gas in liquid form. This is way cheaper as it requires lesser energy consumption. The costs involved excluding the gas itself are quite surprising since mixing the water with silica only requires a normal blending machine – which is locally available.…

    Calorimetry allows for the heat of the solution to be calculated since the heat capacity of the calorimeter is known and the change in temperature is observed. The heat capacity is the ability for the container to retain the heat the is produced or absorbed without allowing for the outside environment to impact the reaction. This closed system allows for easy calculations where q_rxn+q_water+q_calorimeter=0. This is important to the lab that the total heat lost and gained must all equal zero. It would be hard to calculate how much heat was lost in the world by the experiment, so isolating the system to the calorimeter allows for the…
