Salt Water Hydration Lab Report

743 Words3 Pages

These results were worthwhile as it can be useful to assist high-intensity endurance athletes to maintain peak performance through hydration. In these events, liquids are not readily available so it is useful to know which liquid evaporates the slowest so that they can get the most out of a liquid, and hence the hydration out of that given drink, in this case, it is Salt Water. It's also useful to assist people when exploring deserts or hot countries like Australia. In hot climates, liquids evaporate faster as more energy is present. This experiment is useful for tourists, so that they know to stay hydrated and make sure they are always covered in any situation in the areas of hydration.

If the experiment was carried out using these brief measurements, it could have resulted in marginally different results. It could've affected the average number of milliliters evaporated in a 24-hour period for each liquid. However, this was helped by using a smaller 100mL measuring cylinder when needed to create more complex, accurate and detailed measurement, to get the proper number of averaged milliliters evaporated. This measuring cylinder also eliminated part of the human eye problem, as humans can interpret measurements differently from specific angles, this was also helped by putting my chin on the same desk so that the same angle is achieved and measuring from the bottom of the ellipse, which in turn improved the accuracy of the measurements. Another factor that affected the experiment and reliability, is that part of each liquid stuck and stayed in the divots in the disposable cups (as seen in the result photos), this was partly fixed through, shaking and hitting each disposable cup with the liquid whilst pouring it into the measuring cylinder. This didn't really work and resulted in each liquid having less liquid left, affecting the average milliliters evaporated over a 24-hour time period in the long run. It can be seen that the experiment was pretty valid as not much when wrong in the experiment, however, its validity could have been improved by eliminating certain aspects of the surrounding environment and human characteristics, e.g

How Fast Does Alka Seltzer Make Gas

621 Words | 3 Pages

The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react.

Stoichiometry Lab Report

The cylinder was adjusted to the water level because that kept the pressure on the tube and the water inside at a constant rate throughout the tube. If the graduated cylinder had not been adjusted, the test would have been introduced to a random error because it would have been a flaw that was always present and would affect the measurements of the experiment. When the unknown anti-acid was tested the first time, the results yielded a 40.2% yield of CO2. The second trial of part B was not as accurate due to using a mass of the unknown-acid that was too small for accurate results. The lack of accuracy came from a lack of precision which resulted in a human error because the amount that was broken off and selected for the trial was too small.

The hypothesis made, the density calculated in the experiment will stay the same because the density of the unidentified object will never change, was supported. The results support the hypothesis because in every trial the density always came out to 9g/mL. In trial one the mass was 71.16g, the volume was 8mL, and the density was 8.895g/mL, but when rounded to the proper sig fig came out to 9g/mL. In trial two the mass was 71.12g, the volume was 8mL, and the density was 8.89g/mL, but when rounded to the proper sig fig came out to 9g/mL. In trial three the mass was 71.14g, the volume was 8mL, and the density was 8.8925g/mL, but when rounded to the proper sig fig came out to 9g/mL. When averaged the mass was 71.14g, the volume was 8mL, and the density was 9g/mL. Errors that could have occurred are, not calculating the density correctly, not completely submerging the unidentified object with water in the graduated cylinder to get the volume, not rounding the sig figs correctly when finding the density, not measuring the unidentified object’s mass in grams, not measuring the unidentified object’s volume in milliliters, and not writing the correct units with the proper number or not the correct unit at all.

Besides the inaccuracy in determining the freezing point and problems in the enthalpy of dissolution, the largest source of error was the temperature probe. Over the course of the multiple trials, the temperature probe would read somewhat inconsistent values. Due to this uncertainty, trials were performed on pure deionized water to see how far the probe read from zero degrees Celsius. Another source of error was in the calorimeter. Using two foam cups as a calorimeter is sufficient, although far from perfect.

Each group is given three thermometers either alcohol or mercury thermometer of different brands. A GPS device to determine the accurate area and elevation area of the experiment. Three thermometers were given to each group one thermometer to determine the area’s temperature and the two other thermometers are used to determine the relative humidity of the area. In determining the temperature hold the thermometer above your head for three minutes and then read the result, allow the thermometer to stand for about two minutes before getting the next reading. Due to the unavailability of the sling psychrometer regular thermometers were used in determining the relative humidity.

The experiment tested vapor pressure, viscosity, and surface tension. The vapor pressure was tested by putting a drop of the liquid on the laminated paper and waiting 30 second to see which one had reverberated. The viscosity was tested by putting a drops of different liquids on the laminated paper and holding the paper vertically to see which one fell the fastest. The surface tension was tested by how far the liquid spread when a drop of it was put on the laminated paper.

In modern scientific terms, the experiment would be deemed a failure. When looking back at the data, one is unable to verify its credibility. The results of an experiment are supposed to be able to be recreated in other labs if one follows the steps, but there are no concrete steps to follow throughout the whole procedure, and there is the ethical issue of using human test subjects. According to the data, Dr. Rascher believed he had figured out how long it takes a body to cool, and that the best re-warming method was a hot bath. Others have argued that neither of those assertions are true, however.

How Do Different Liquids Affect The Rate Of Evaporation

340 Words | 2 Pages

The hypothesis for this experiment was accurate, as the liquids evaporated at different rates. Also, the hypothesis stated that nail polish remover would evaporate at the fastest rate, which it did, at an average rate of 28.2 mL per day. The salt water evaporated at the slowest rate at an average of 9 mL per day. The other liquids evaporated at very similar rates. These results occurred because the characteristics of each liquid effect the efficiency of evaporation.

Water Hydration Lab Report

In this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up
