Rate Of Reaction

Title The effect of arise compass on the invest of reply of milligram and hydrochloric acid Research Question How stick out the surface area bushel the rate of chemical chemical reaction of milligram and hydrochloric acid? Hypothesis In a chemical reaction, on that point are a few factors that see the rate of reaction such as temperature, assiduousness of reactant, and surface area of reactant. These factors ordain increase or decrease the rate of reaction. The hypothesis that tin can be derived is that the higher(prenominal) the surface area of reactant the rate of reaction will increase. Variable Independent protean: types of atomic number 12 (atomic number 12 strips and atomic number 12 powder). Dependent variable: rate of reaction. Constant variable: temperature, concentration of hydrochloric acid and volume of hydrochloric acid. Apparatus 1 conical flaskful, 1 stopper, 1 connecting tube, 1 burette, 1 basin, 1 retort stands, 1 stopwatch, 1 digital weighing machine, 1 measuring piston chamber Materials 0.02 M hydrochloric acid, magnesium strips, powder strips, distilled water, water Methodology 1. progress to the apparatus according to plat A. 2. Prepare 100 cm3 of 0.2 M hydrochloric acid by commingle 10 cm3 of 2 M hydrochloric acid with 90 cm3 of distilled water. 3. carry the conical flask with 50 cm3 of 0.2 M hydrochloric acid. 4. Weight up 0.

2 g of magnesium strips. 5. Put that magnesium strips into the conical flask which contains 50 cm3 of 0.2 M hydrochloric acid. 6. Immediately close the conical flask with stopper an d snuff it stopwatch. 7. Record the vo! lume of gas in burette in every 30 seconds for 5 minutes. 8. put off the edition obtained from the reaction. 9. Repeat the experiment by using 0.2 g magnesium powder. 10. Plot a graph for both experiments. 11. inscribe the rate of reaction for both experiments from its respective graph. Compare which reactions charter higher rate of reaction.
