Formula For Hydrate Research
1) 0.069 mol MgSO4/ 0.015 mol H2O = 4.6 = 5
Formulae for hydrated MgSO4 = MgSO4 5H2O

2) There are at least two reasons why heating to find percentage of water in hydrated crystals is not recommended for all hydrates. The first reason is that some hydrates have such a strong bond with the water that not all of it will be able to be removed. The second reason is that different hydrates have their own mass. Depending on the mass and type of hydrate, some of the molecule may be burned off from heating. This would lead to a false accusation that the mass loss was all from water, when in reality it could partially be the mass of the molecule.
3A) It is important to let the evaporating dish cool before measuring it for a few reasons. Besides

    In this experiment, the molecular weight of a condensed vapor was found through a procedure using an unknown liquid. The flask before adding the unknown liquid in was full of air. After the beaker full of water started to boil the flask was examined until the unknown liquid was completely vaporized. At that exact point the flask contained all vapor. At the final weighing the flask contained condensed vapor and air. There is always a chance for error. Some sources of error could have come with completing this lab over an open water bath and some water vapor may have been in place. Also, too much vapor could have escaped and the experiment might not have been stopped quick…

    Using the buret to read the volume of water is a source of random error because it is marked to the nearest 0.1mL. Therefore, our data could be above or below the actual volume of water in the buret because we took our reading to the nearest 0.01mL, which increases our uncertainty level. Along with taking our volume readings to the nearest 0.01mL, a random error also arose when we took the reading of the temperature of the water. The thermometer only read to the nearest tens places, therefore our readings went to only the tenths place which could have been measured inaccurately giving rise to more uncertainty and random error within the lab. We were able to limit our uncertainty level when taking the masses of the beaker with and without water, by using the analytical balances which read to the nearest ±0.0001g.…

    Hydrate Formula

    This is supported by the experimental data collected from the experiment. From our data, it can be easily calculated that the mass of the lost water was .96g and the anhydrous salt left behind massed at 1.49g. Using this information it can be determine the moles of each substance (.96g/18.02g=.053 moles of water, and 1.49g/159.62=.00933 moles of anhydrous salt). This is possible to calculate due to the scientific understanding that the mass of an element in grams divided by its average atomic mass will calculate the moles it’s equivalent to. After calculating the moles of each, the ratio .053 moles of water to .00933 moles of anhydrous salt is formed. Then, by dividing the moles of water by the moles of anhydrous salt a ratio between the two will be formed. This is because of a scientific principle that when dividing the moles of one molecule by another will result in a proportion of moles of one element to 1 mole of the other. The calculation produces 5.6806 moles of water/1 mole of anhydrous salt and after rounding to the nearest whole number the ratio 6 moles of water to 1 mole of anhydrous salt forms. Last, when plugged into the chemical formula of the hydrate (copper (ii) sulfate), the result is 1CuSO46H2O, which is the formula of the…

    Obtain and wear goggles. 2. Measure and record the mass of a clean, dry crucible without cover. Obtain about 1 g of the unknown copper chloride hydrate and place it in the crucible. Use a spatula to break up any large pieces of the substance by pressing the pieces against the wall of the crucible. Measure and record the mass of the crucible with compound. 3. Set up a ring stand, ring, and clay triangle for heating the sample. Rest the crucible on the clay triangle. Set up a lab burner and ignite the burner away from the crucible. Adjust the burner to get a small flame. 4. Hold the burner in your hand and move the flame slowly back and forth underneath the crucible to gently heat the sample. Do not overheat the compound. Note the color change, from blue-green to brownish, as the water of hydration is driven out of the crystals. When the sample has turned brown, gently heat the crucible for two more minutes. 5. Remove and turn off the burner. Cover the crucible and allow the sample to cool for about ten minutes. 6. Remove the crucible cover and inspect your sample. If you see any blue-green crystals, reheat the sample until the crystals have turned brown. 7. Measure and record the mass of the cool crucible of your copper chloride sample. 8. Transfer the brown solid to a clean and empty 50 mL beaker. Rinse out the crucible with two 8 mL aliquots of distilled water and pour the water into the 50 mL beaker. Gently swirl the beaker to completely dissolve the solid. Note that the color of the solution is green as the copper ions are rehydrated. 9. Measure out about 20 cm of aluminum wire, coil the wire, and place the wire in the beaker of solution so that it is completely immersed in the copper chloride solution. Note that the reaction produces a gas, elemental copper is forming on the surface of the aluminum wire, and the color of the solution is fading. The reaction will take about 30 minutes to complete. 10. When the reaction is done, the solution will be colorless.…

    Hydrate Composition

    By calculating the difference in the mass of the hydrate copper (II) sulfate and the anhydride we were able to determine the mass of water in the hydrate. This information was then used to determine the empirical formula of the hydrate, defined as a compound formed by the addition of water to another molecule. In the first trial, the mass of water in the hydrate was determined to be 0.41 g, while in the second trial the mass of water was 0.52 g. Moles of water associated with a single mole of anhydride were then calculated for both trials, giving the values of 4.7 and 4.5 moles of water, respectively. This indicated that the empirical formula of the hydrate might be copper (II) sulfate pentahydrate – CuSO4·5H2O.…

    Hydrate Lab Report for Chemistry Lab

    The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample. This ratio was then used to write the new and balanced equation of the dehydration process. The sample was then rehydrated to the original state and the percent of the hydrate recovered was calculated by using the mass of the rehydrated sample by the mass of the original hydrate and then multiplied by 100%.…
