Tap Water Electrolytes Experiment

Throughout the experiment, there was a struggle to keep the heat stable which led to inaccurate data. Additionally, while changing the receiver from cyclohexane to toluene there was a loss of distillate which also led to the errors observed in the data. Furthermore, if more data were collected for each compound it would be a better representation of the experiment's results. If these errors were avoided, then the experiment would be more efficient in distilling the two compounds from each other and the plateau would be as sharp as figure 6 in the lab

I think that this is because the company may have wanted miranda to be more gassy and put more carbon dioxide in or the acidic substance of oranges in miranda reacted stronger with the carbon dioxide. However there is a high possibility that our first test for miranda may have a couple of mistakes made since it was a large amount further than its other results(1st test: 3m, 2nd & 3rd test: 1.5m). This may be because we have shaken it too long, measured the results incorrectly, opened the can differently, changed the angle accidentally or since different people were shaking the can… Our method uses measuring distance to find out how well each soda propelled.Our strengths and limits in this method include many things. Strengths include it is accurately measuring the how well the gas and liquid has been propelled, is mostly safe and easy to gather results. The limitations include a large amount like: unable to tell which soda mark is which on the ground, not having the ability to know we are shaking at the same force, not having the most accurate measurer and tool, not able to stop at just the right time, not fully opening the

For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.

The bubbles in the carbonation would cause an inaccurate reading because the light would pass through the clear gas bubble. So do get rid of the bubbles we let the cola simmer on a hot plate. It is important to not let the cola boil because if the water in the cola evaporated it would make the cola more concentrated. The reason that the absorbance of PO43- ion and concentration graph was used instead of the transmittance of PO43- and concentration is used is because concentration and absorbance are proportional, therefore having a linear line of best fit were the absorbance could be used to calculate the PO43- concentration. Whereas if the transmittance of PO43- and concentration does not have a linear relationship so calculating the PO43- would be more

The last person I interviewed asked if energy drinks had a higher voltage compared to water or if they had the same voltage. All liquids have a voltage this is where we get our energy from. The reason energy drinks have a voltage is because of the high amount of caffeine they have in them and the reason water has a voltage is because of the process that water goes through to be cleaned. The water particles rubbing together cause friction giving the water a static electric charge. In order to test which energy drink has the highest voltage to give the most energy I am going to use a zinc nail, copper wire, a volt meter and four different energy drinks and water.

• The ingredient L-Arginine opens the blood vessels thus cool supply of oxygen and eradication of wastes. • It assists in burning fat by raising the body heat and metabolism • it boosts sexual performance. • It helps stimulate testosterone. What’s Bad about Novasta Labs Total Test? Numerous ingredients are used in this supplement with less advantage to boosting testosterone hormone, hence not useful to different individuals whose core value is based upon boosting their testosterone hormones.

Would tap or distilled water be better for a rose? Distilled water is made when the pure H2O is boiled out of its contaminants. {minerals}The steam from the boiled water is condensed which leaves all chemicals, chlorine, heavy metals, and dissolved solids behind. Distilled water has been used for centuries. It is used to top off acid batteries in cars.

One of the possible reasons for the poor result could be that the techniques were basic. We used a hot water extraction, and organic solvent extraction and a rotary evaporator technique which could not have given us crude caffeine. Further purification steps needs to be conducted in order to obtain crude

Substrate concentration basically means the amount used for the substrate. The substrate in our experiment was 0.1% hydrogen peroxide. The 0.1% is the concentration amount. Just like temperature and pH, substrate concentration can speed the reaction only up to a certain limit. When we mixed pH 3 enzyme tube with substrate tube, we used 0.3 mL of hydrogen peroxide, but if we were to increase the amount, then the experiment would have been faster.

Therefore, improvement to the method would be to make the higher light intensities so as to be quite accurate, which denotes lamps would be adjusted to a beaker containing elodea from side to side because the smaller light intensities would be less accurate since the light spreads out, and the elodea might be exerted influence on other experiments or background light. Lastly, the other fallacy derives from the water temperature. As the temperature of the water increases, carbon dioxide is produced up until its optimal temperature. In reality, when the plant attains the optimum, denaturalization of enzymes in elodea occurs so that that leads to cessation of oxygen. Similar to this situation, same result would be created when the temperature is too cold.
