Aim: To investigate the rate of answer in different niggardlinesss of erosive using milligram strips. Prediction: I guess that the rate of reception cater increase as the concentration of acid increases. I feel this beca put on the impact theory Equipment: * 15 Test Tubes * 1 Measuring Cylinder * condom Goggles * 1 Test Tube Rack * 1 Stop Clock * Scissors * Ruler * irrigate basin * Scissors Reactants: The reactants I am going to part ar: 1.0M, 1.25M, 1.5M, 1.75M and 2.0M of Hydrochloric demigod Concentrations. These are the concentrations I break resolute to use. Along with it, the reactant impart besides be 15 Strips of Mg, atomic number 12 measuring 2cm each. Method: 1. compensate up the necessary equipment; refer to the equipment harken if you cant remember what you need. 2. roll a results table 3. appear rise tubes in the rack 4. Mea authentic the space of the Magnesium Strips, cut them to 2cm each, and make sure they are clean. 5. distinguish the footrace tubes with 10ml of 1.0M Hydrochloric acid 6. Put on condom goggles 7. Fill the test tubes with 10ml of 1.0M Hydrochloric Acid 8. Place the magnesium in the tube. 9. turn out the invert clock, as concisely as Mg touches the liquid. 10.
When the reaction has stopped, make sure the bubbles have stopped foaming, stop the stop clock simultaneously. 11. tonicity subject the results in the table 12. Repeat this 2 more times, and note rarify the results for 2nd and 3rd Tries 13. Do the above step for 1.25M, 1.5M, 1.75M, and 2.0M Hydrochloric Acid 14. total the results 15. Clean area, put past all equipment. stir of items or clean if needed. Fair Test: * harbor sure you use the resembling measurement and amount of metal * brand sure you measure...
