Hydrated Compound

554 Words3 Pages

Purpose and Techniques: This experiment has the aim to determine a chemical formula of hydrated compound, which ingrains cupper, chloride and water molecules in its structure. In order to find this hydrated compound, it is necessary to use the law of multiple proportions. In other word, finding the appropriate variables values to this compound (CxCly*zH2O). Additionally, two major steps are required to proceed the experiment. The first consists to heat a sample to liberate the water hydration, and then compare two mass weights before and after heating so gets easier to find the water percentage (mass). Second step consists in chemical processes with the sample that drives to determine the percentage of the other element. Materials and chemical …show more content…

Before starting the heating process, measure the weight of the crucible with its cover first and then tare the balance, and after that adding about 1 gram of the sample to the crucible with its cover, and then weigh it. Moreover, it is possible liberating harmful gases during the process of heating; therefore, being careful is important. The heating process ends when this sample changes the color to brown because water of hydration is removed to the sample. Additionally, give time to the small cool down and measure its weight. Next, transfer the sample to a 50 mL beaker and mixes with distilled water, which gets by rinsing the crucible with its cover in 8mL, so the solution is generated. After that, put an aluminum wire into the beaker, and after a certain period of time the solution gains color. To finish the reaction, 5 drops of 6M of Hydrochloric acid is added into the beaker to clean the solution, which means that acid dissolves all salts of aluminum that is on the solution. After finishing the chemical process, collect and use the Butcher funnel to wash the cooper because it is going to be used to a vacuum filtration. After finishing the filtration, measure the weight of the sample and dry it. Finally, Do again these two steps until notice that the subtractions of these masses are about 0.005 g, and then arrange all the chemical

    Next, about 10 mL of both solutions, Red 40 and Blue 1, were added to a small beaker. The concentration of the stock solution were recorded, 52.1 ppm for Red 40 and 16.6 ppm for Blue 1. Then, using the volumetric pipette, 5 mL of each solution was transferred into a 10 mL volumetric flask, labelled either R1 or B1. Deionized water was added into the flask using a pipette until the solution level reached a line which indicated 10 mL. A cap for the flask was inserted and the flask was invented a few times to completely mix the solution. Then, the volumetric pipette was rinsed with fresh deionized water and

    After placing the aluminum in said beaker, one should gather a stir stick and stir the solution in order to speed up the reaction. One should stir the solution until there are no visible silver pieces of aluminum left in the beaker of what was the copper (II) chloride solution. When there are no visible silver pieces of aluminum left in the beaker, this means that the reaction has occurred. After the reaction has occurred, one needs to separate the products, which are copper and aluminum chloride, from each other in order to see how much copper was able to be produced. Seeing as the products are a solid in the form of copper and a liquid in the form of aluminum chloride, the process of filtration can be used to separate them.

    Students first prepped for the lab by cleaning out the crucible. Three boiling chips were added in the crucible once it was wiped out with a paper towel. The crucible was then placed on a clay triangle two finger widths above the Fischer burner. After 10 minutes of the crucible being directly under the flame, the it was clean and students allowed time for it to cool down. Next, the students from then on used tongs to transport the crucible from weighing it and back to the clay triangle.

    Percentage Composition of Hydrates The Introduction: Hydrates are ionic compounds and are often a type of salt with a definite amount of water as part of their structure. Hydrates are decomposed into anhydrous salt, a no-water compound, and water vapor when heat is applied; water vapor is released from the hydrated compound, which leaves with an anhydrous salt that weighs less than the hydrate. But how do we find the percent of the water that was lost after applying heat to the hydrates and how accurate is finding the percent composition of water using experimentation and a gram weight scale? The purpose of the experiment is to find the percent of water lost by finding the difference between the mass of hydrate and the mass of anhydrous

    In this lab, three unknown compounds were separated from a mixture and identified by melting point. Unknown mixture #124 has components of acid, base and neutral compound. The compounds were identified by melting point and matched up with the known melting points from a given list. In order to identify the compound it was important to separate by dissolving the mixture in an organic solvent which was not soluble in water, and then extracting the solution first with HCl, and then dilute sodium hydroxide solution. From the separation mixture, the aqueous layer were obtained and labeled as TT-1 (base), TT-2(acid) and TT-3 (neutral) in three different test tubes for later recovery.

    In order to properly appreciate the importance of aluminum recycling in our world, an aluminum recycling experiment was done through alum synthesis. The process by which this was done recycled solid aluminum can pieces (Al) into the form of solid raw alum crystals (KAl(SO4)2) through a series of reactions. Application of this experiment comes from analyzing the calculated percent yield of alum crystals, understanding where error is involved, and determining how a perfect yield could be obtained. First, 0.9-1.2 grams of aluminum pieces were weighed out and placed in a 250 mL beaker, in which 50 mL of 1.4 M KOH solution was added and a fume hood was placed. The mixture was placed on a hot plate and stirred to speed up the reaction.
