    Then from this number the amount of water that was in lost was measured at 1.1 g. After this then the number of moles of anhydrous were calculated from the molar mass of anhydrous. Then the moles of water were calculated. Then the stoichiometric coefficients for each component were calculated. The results found that there was two moles of anhydrous and 35 for water. Thus the empirical formula was found to be:…

    Copper Chloride Hydrate Lab Report

    In order to find the formula of the copper chloride hydrate, we had to separate the compound to find the mass of water and copper. To begin this process, we evaporated the water and created an anhydrous compound, meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds, we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations: Part I: Dehydration of Hydrated Copper Chloride), which showed how much of the compound was copper chloride by mass. Since there are only two stable forms of copper chloride, we concluded that possible formulas would be either CuCl or CuCl2. Intending…

    Epsom salt have many uses, including use as bath salts, as a laxative and as a plant nutrient. Epsom salt contains hydrated magnesium sulphate which has the formula MgSO4.xH2O. Experiment to find the value of x in a pure sample of hydrated magnesium sulphate. The method i will use is heating a known mass of magnesium sulphate to remove the water of crystallisation. x is found by weighing before and after heating to find the mass of the water then using the moles calculations to find x.

    Osmosis Lab Report

    Diffusion and Osmosis are two concepts that go hand in hand with each other. Diffusion is simply described as the movement of a substance from a region of high concentration to a region of low concentration. In another words, the substance will move down its concentration gradient which is “the region along which the density of a chemical substance increases or decreases” (Campbell Biology pg. 132). If you understand the concept of diffusion then osmosis is a very simple process. It can be defined as the diffusion of water across a permeable membrane. Osmosis can be cellular or artificial, so even though we are creating artificial cells in this lab, it is still considered to be osmosis. During osmosis, a solvent is trying to get through a selectively permeable membrane to make the concentration of that solvent the same on both sides of the membrane. The rate of osmosis depends on the type of environment the cell is in. There are three different environments that a cell can find itself in, a hypertonic environment, a hypotonic environment, or an isotonic environment. The environment a cell is in will determine its tonicity which is “the ability of a surrounding solution to cause a cell to gain or lose…

    Osmosis Lab Report

    The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane. (Miller/Levine) Osmosis occurs when there is an area of higher and lower concentration. Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic, hypertonic, and isotonic. When in comparison to another solution, a hypertonic solution has a lower concentration, a hypertonic solution has a higher concentration, and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different concentrations. The hypothesis is that an egg placed in distilled water will gain mass while an egg placed in syrup would lose mass.…

    Lab Report Osmosis

    The main purpose of this paper is to assess the rate of change with osmosis for different concentrations of sucrose in artificial cells. Since the human body is composed of trillions of cells that contain roughly 85% of water, makes osmosis a very important concept (Carmichael, Grabe and Wenger). The forces that affect osmosis are the concentrations of solutes surrounding the cell or inside of the cell. Water will then move across the cell membrane and create a balance of water between the cell and its environment (Reece et al. 133). In order to calculate the average rate of change for our artificial cells, we must understand tonicity as the ability of a nearby solution to cause a cell to lose or gain water, depending on its concentration of non-penetrating solutes relative to solutes inside the cell (Reece et al. 133). The dialysis bags used in this experiment have membranes which are selectively permeable, which only allows particles specifically small enough to pass through (Carmichael, Grabe and Wenger). In a hypotonic solution, water…

    The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand, the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose. Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments.…
