Magnesium Ribbon Lab Report
1. The clamp stand was placed on the heat resistant mat. Then the clamp stand was used to secure the glass syringe.
2. The test tube with a side pipe was connected with a glass syringe.
3. About 3 cm of magnesium ribbon was measured out using a ruler.
4. The magnesium ribbon was polished using steel wool to remove any coating of oxides as magnesium can be a reactive metal. When magnesium is exposed to oxygen it reacts to form metal oxides. This step is necessary in order to obtain reliable results.
5. The mass of magnesium ribbon was measured and recorded using top pan balance.
6. Step 3, 4 and 5 was repeated four times.
7. 3M of hydrochloric acid was diluted into 30 mL of the following concentrations: 2.0M, 1.5M, 1.0 M and 0.5 M. This …show more content…
20 mL of 3M hydrochloric acid was measured out using graduated cylinder. Then 10 mL of distilled water was added to get 30 mL of 2M hydrochloric acid. The solution was poured in conical flash and labeled.
10. 15 mL of 3M hydrochloric acid was measured using graduated cylinder. About 15 mL of distilled water was added to make 30 mL of 1.5M hydrochloric acid. Then the solution was poured in conical flask and labeled.
11. 10 mL of 3M hydrochloric acid was measured using graduated cylinder. Then 20 mL of distilled water was added to make 30 mL of 1.0 M hydrochloric acid. Solution was poured in conical flask and labeled with its concentration.
12. To get 30 mL of 0.5 M hydrochloric acid, about 5 mL of 3M hydrochloric was mixed with 25 mL of distilled water. The solution was poured in conical flask and labeled.
13. The stopwatch was rested to zero.
14. The first concentration of 30 ml of 3M hydrochloric acid was poured in the test tube which was connected to a pipe and glass syringe.
15. Magnesium ribbon was placed in the test tube and the cork was put.
16. When the magnesium strip was dropped in the hydrochloric acid, the stopwatch was started.
17. The stopwatch was stopped when the hydrogen gas reached the volume of 40 cm3. Time taken for the reaction was
