Background Information:
Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong, silvery-white, light-weight metal (one third lighter than aluminum). In a powder, it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk, but once ignited, it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with a thickness of about 0.03mm, and weight of about 25 grams. Hydrochloric acid is a solution of hydrogen chloride in water, that is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid. Hydrochloric

Variables: Manipulated - Concentration of HCl
Responding - Reaction time of HCl and Mg
Controlled - Size of Mg piece, amount of HCl in test tube, room temperature, method of agitation.

Materials List: 1. Test tube rack 2. Graduated Cylinder (10mL) 3. 3 Test Tubes 4. 50 mL beaker 5. 250 mL flask (for the HCl) 6. Dropper 7. Stopwatch 8. 17cm strip of Magnesium Ribbon 9. HCl (.5 molarity) 10. HCl (1 molarity) 11. HCl (2 molarity) 12. Goggles 13. Scissors/Knife (for cutting Mg)

Procedure: 1. Cut the strip of magnesium into 10 mm pieces with the scissors/knife and then hold them in the beaker. 2. Measure out 5 mL of HCl (.5 molarity) with the dropper into the graduated cylinder. 3. Pour HCl (.5) from the graduated cylinder into the test tube. 4. Put a piece of magnesium into the test tube filled with HCl. 5. Start stopwatch when the magnesium is placed into the test tube filled with HCl (.5) and stop it when the magnesium has dissolved (flick the bottom of the test tube periodically to make sure that the magnesium mixes properly with the HCl). 6. Record your data and then dump out the HCl and wash your materials. 7. Repeat steps 2-6 with .5 molarity until you have completed 5 trials with it. 8. Get a new test tube. 9. Repeat steps 2-6 with 1 molarity. 10. Repeat steps 2-6 with 1 molarity until you completed 5 trials with it. 11. Get a new test tube. 12.

    First the student will take the weight of a clean dry beaker and record the data. Next ass .15g of the first unknown substance. From there, the student will add 50ml of water to the beaker then dissolve the .15g of the first unknown substance into the water. Once the substance has dissolved, the student will add 10 drops of bromocresol (indicator) into the beaker. After the student will fill the buret all the way up with HCl. Once that is done, begin titration. The HCl should be added into the beaker until the indicator turns green. After it turns green the student will then place it on a hot plate and heat it till the CO2 evaporates and it turns blue again. After that let it cool. Once the substance is cooled. The student will then titrate once more till it turns yellow. The yellow color indicates that the substance has stabilized. Once the substance is fully titrated, the student will place the beaker back on to the hot plate and let all of the water evaporate out of the beaker till there is only the salt (unknown substance) left. Lastly, the student will then measure the weight of the beaker with the salt in it and record the data. Once the data has been obtained the student will subtract the weight of the beaker from the weight of the salt. That calculation will then be used to find the…

    Previous to the reaction, the magnesium appeared to be a solid, white, black, and grey substance with many small dark particles within the substance. The hydrochloric acid was a clear liquid that looked like water It weighed 42.2 grams in total. During the reaction, the two substances produced bubbles, creating smoke and became warm with a smell that is irritating to the human nose. After the reaction, it appeared to be a clear, bubbly liquid with white spots. It weighed 42.2 grams in total after the reaction. The creation of bubbles, the different smell, and the increase in temperature told me that a chemical reaction occurred within the substance.…

    For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate, and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but, we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment.…

    Magnesium, an abundant mineral in the body, is naturally present in many foods, added to other food products, available as a dietary supplement, and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation [1-3]. Magnesium is required for energy production, oxidative phosphorylation, and glycolysis. It contributes to the structural development of bone and is required for tToo much magnesium from food does not pose a health risk in healthy individuals because the kidneys eliminate excess amounts in the urine [28]. However, high doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping [1]. Forms of magnesium most commonly reported to cause diarrhea include magnesium carbonate, chloride, gluconate, and oxide [11]. The diarrhea and laxative effects of magnesium salts are due to the osmotic activity of unabsorbed salts in the intestine and colon and the stimulation of gastric motility [55].…
