Calcium Chloride Lab Report
Experiment 2
Purpose: To determine energy lost by Calcium Chloride and gained by Ammonium Nitrate when dissolved in Water.
Theory: Exothermic reactions are when net energy is lost in process of reaction. When solid calcium chloride (chemical formula CaCl₂) is placed in water, the calcium chloride dissolves and liberates heat in the process. Calcium chloride is one of the ingredients in instant "hot packs" sold in retail stores. Some concrete mixes incorporate calcium chloride to decrease drying time. Calcium chloride is also used as a de-icer.
Endothermic reactions are when net energy is used in process of reaction. When we dissolve ammonium nitrate the temperature of water falls because the salt is gaining in potential energy. That is why

    Lab 3C Report

    This experiment is a continuation of the lab’s efforts to purify L-LDH. Previously our enzyme was purified through anion-exchange chromatography on Q-Sepharose, but to get the enzyme out of the stationary phase NaCl was added to salt it out. However salting out the enzyme prevents using chromatography because of NaCl’s high ionic strength. Dialysis was used to remove the salt from the enzyme sample, when put into a membrane bag which uses principles of equilibrium to remove the salt via nanometer sized holes in the membrane bag which allow for water and small molecule transport. However, dialysis must be done twice, as not all the molecules of salt will leave the dialysis bag because dialysis uses Le Chatelier’s principle equilibrating the bag. The top of the bag has an air pocket introduced to allow for floatation which prevents the stir bar from damaging its contents.…

    Exothermic Reaction Lab Report Essay

    Both of the activities rise in temperature, showing the increase of the heat. This is because the reactants in the exothermic reactions had a greater amount of heat content than the products, and therefore producing a negative enthalpy. Activity B however created an endothermic reaction, absorbing heat from its surroundings, due to its lack of energy. Ammonium Chloride and Water had shown to have more products than reactants; and this consequently produced a positive enthalpy change. As Activity A and B produced exothermic reactions, they are most suitable for heat and eat packs. This is due to the fact that exothermic reactions project heat to its surroundings, and therefore heating the…

    Lab Report Determining The Properties Of An Unknown

    Solubility is the amount of solid that can be dissolved in a certain amount of liquid at a certain temperature. In order for solubility to be tested, two trials were run. 5 mL of deionized water was measured and poured into a beaker. The temperature of the water was recorded. 2 grams of the unknown was measured out and placed into the same beaker as the deionized water. The unknown and water was then mixed well until the unknown was fully dissolved. Once the unknown was fully dissolved, small amounts of the solid unknown was then measured and mixed into the solution until the solution was either cloudy or had small amounts of solid unknown, unable to dissolved, at the bottom of the beaker. The solubility was then put into terms of moles per liter. Enthalpy change is the amount of heat that is released or absorbed in a chemical reaction at constant pressure. For enthalpy change to be calculated, 30 mL of deionized water was measured out and put in a coffee cup calorimeter. The initial temperature of the water was record. 1 g of the unknown was measured out. Fairly quickly, the unknown was added to the water and stirred. The LabQuest pad measured the change in the temperature of the water as the unknown was dissolved. Once 90 seconds had passed the heat trend was observed from the reaction. The enthalpy was calculated by using the formula, ∆H= c∙m∙∆T. The enthalpy change…

    Sodium Chloride Lab

    In the experiment, we tested a sodium chloride solution. Along with the tested solution, control groups (water and sodium phosphate) were used to be help understand whether or not NaCl was a buffer. Water was the negative control group and sodium phosphate was the positive control group. If NaCl was a buffer than the pH would be stabled as the sodium phosphate buffer. If NaCl was not a buffer than the pH would fluctuate like the negative control, water. During the first trial and prior to the drops of 0.5 M of HCl acid, the pH of sodium chloride was 7.50. After the addition of 5 drops of 0.5 M of HCl, the pH decreased by 4.83 and ended at 2.67 on the pH scale. When comparing the results of the sodium chloride to the control groups, the total pH change of sodium phosphate was only…

    Yr 12 Chemistry EEI - Chemcial Reaction Ice Pack

    Abstract: Cold packs are based on the principle of endothermic reactions, which means a reaction that absorbs heat from the surrounding resulting in a temperature drop. Due to this temperature drop, cold packs have many benefits when it comes to injuries such as sprains and strains. It cools the local tissue and reduces bleeding, swelling and pain. It also aids in a speedy recovery. The most commonly used chemical in instant cold packs is ammonium nitrate which will be tested in the investigation along with four other chemicals in water. These other chemicals include potassium nitrate, potassium chloride, sodium acetate and sodium chloride. The two lowest chemicals will then be mixed together at different concentration ratios to see if this drops the temperature further. The chemical/s the produce the lowest temperatures will be tested and compared against a normal frozen cold pack.…
