Observing a Chemical Reaction

            
            
             The purpose of this lab was to observe a chemical reaction between copper chloride and aluminum foil.
             II. Materials.
             1 100-mL beaker.
             1 thermometer.
             1 glass stirring rod.
             water.
             1 plastic spoon.
             1 pair of safety goggles.
             1 weight boat.
             III. Procedure.
             1. Take a small sample of the copper chloride and put it in the weight boat. Observe the crystals and note as many details about it as possible.
             2. Fill the 100-mL beaker about one-fourth full of tap water. Without stirring, add the copper chloride to the water. Record any observations of both the crystals and the water.
             3. Stir the mixture with the glass rod until the crystals have completely dissolved. .
             Record observations of the mixture.
             4. Place thermometer is the mixture and write down current temperature. Then .
             loosely crumble the foil and place into the mixture. Observe from the side for about .
             10 minutes and note any changes in the temperature. .
             5. When the reaction is complete, pour the liquid portion of the mixture into the sink. .
             Discard the solid contents into the chemical waste container. Wash and dry the .
             equipment used, then wash your hands thoroughly before leaving your station.
             IV. Data and Calculations.
             See data on other paper.
             Calculations: DT.
             Highest recorded temperature: 100°C.
             Original temperature: 22°C.
             Difference: 78 C.
             V. Discussion and Conclusion.
             In this lab, we determined that there would be a chemical reaction between copper chloride and aluminum foil. When the foil was placed into the beaker with the water and copper mixture, the water began to boil and the foil began to deteriorate. Also, the colors changed from a blue-green color to a brownish purple. The temperature also rose very quickly from 22°C to 100°C. After a few minutes, the boiling stopped and the mixture was discarded.
            


Essays Related to Observing a Chemical Reaction

1. The Effect of Temperature on an Enzyme

This means that enzymes work to speed up the rate the biochemical reactions occur, so that chemicals that are required for life functions are made at a faster rate. ... This will be done by coating several paper disks into beakers of differently heated enzymes, and observing how fast they rise to the surface of a solution of hydrogen peroxide. ... This is because increasing the temperature can usually speed up chemical reactions. ... Potato Pulp (Pre-Reaction) Thick, brown, heterogeneous mixture. ... Reaction (Cold) Disk fell to bottom of test tube and quickly came back up. ...

2. Decomposition of hydrogen peroxide.

It increases the rate at which chemical reactions occur by lowering the activation energy. Enzymes are not altered or used up by the reactions they catalyse, so they can be used again to catalyse the reaction of another substrate molecule. ... The way in which enzymes work can be explained by the two following hypotheses: The lock and key hypothesis: In this hypothesis it is believed that the active sites (the lock) size, shape and chemical nature is complementary to the substrate (the key), and so each enzyme catalyses only one type of reaction. ... This was found by observing the dis...

3. Geotropism

In addition, although geotropism was thought to be simply gravity's effect on a plant hormone, Auxin, which is observed to affect many plants reactions to light and growth, also known as phototropism, several other theories are being tested. ... As nastic movements tend to be slow, only noticeable in generally more than hour time periods, which lend themselves to time lapse photography, the preferred way of observing such changes as the ones that geotropism causes. Jacques Loeb (1859-1924), whose works include The Mechanistic Conception of Life, Artificial Parthenogenesis and Fertili...

4. Rational Emotive Thearpy: An Approach To Substance Abuse Counseling

Reaction: Feelings: unlovable, worthless, and depressed. ... Most addicts use chemicals as a means of escape from an unpleasant emotion or situation. ... Another example of conditioning toward substance abuse is children observing adults engaging in substance abuse, usually in positive situations (or what the observing children interpret as a positive situation). ... Once they have inferred that they are not worthwhile, the chain reactions will allow this C to lead to another A. ... Thereby opening a door to a conditioned response to unpleasant feelings, which is to use chemicals to relie...

5. The Basics of Heat Conversion

Other than heat energy, various forms of energy include electrical, light, mechanical, chemical, sound and nuclear energy. ... The process of taking this measurement is by observing the rise in temperature. Calorimetric units measures internal energy changes and enthalpy that accompany a chemical reaction. In thermodynamics, heat transfer is through chemical reactions with a change in the internal energy of a system without change in volume of the system at a constant pressure. ...

6. The Effect Of Varying Enzyme Concentration On The Breakdown Of Hydrogen Peroxide

Inhibitors therefore slow the rate of reaction. ... This was achieved by observing the time taken for the manometer fluid to travel between the two marked fixed points as it was forced through the manometer by the rising gas. ... Safety Laboratory coats were worn during the investigation to prevent chemicals from spoiling clothes. Care was also taken whilst handling the chemicals as hydrogen peroxide is corrosive and the manometer fluid is permanently staining. ... All of these factors are required for an efficient reaction to take place, even when one is freely available the reaction ...

7. Molar Mass Of A Gas

We observed when the HCl was poured into the generator with the marble chips the reaction began immediately causing bubbles to surface. After patiently observing the reaction for 15 minutes while the CO2 filled the flask we recorded the room temperature, and momentarily tightened the stopper on the flask a couple of times to observe that the liquid in the generator is backing up the funnel tube which means CO2 is still being delivered. ... The purpose of the calcium chloride is to absorb the water vapor form the CO2 reaction 4. ... Conclusion In this experiment I concluded the exper...

8. Creation Vs Evolution

Evolutionists believe that a fireball explosion caused by chemicals joining together produced matter and energy. ... Evolutionists believe that life was spontaneously generated on earth, and that chemicals somehow got together to make life. ... Just observing the world's condition over time easily refutes evolutionist's beliefs that the world is becoming more orderly since the "big bang". ... At the end of the experiment, he got tar as one of his results, which is a nuisance in organic reactions. ...

9. Chemistry - The Solubility of Various Substances in Water (H2O)

Water is an excellent solvent because of its chemical composition and physical qualities. ... A predominant trend is evident with an increase in temperature equating to an increase in the rate of reaction in solids and liquids within a solvent. ... Sucrose is formed by the dehydration of a fructose and glucose sugar unit (dehydration reaction). ... Mix well for 1 minute, observing the dissolution 5. ...
