Question 31
The table shows the results obtained from reacting magnesium with five different concentrations of hydrochloric acid.
| Trial | Concentration of hydrochloric acid (M) | Time taken to complete the reaction (s) |
|---|---|---|
| 1 | 0.1 | 150 |
| 2 | 0.2 | 90 |
| 3 | 0.5 | 60 |
| 4 | 0.8 | 70 |
| 5 | 1.0 | 30 |
Work in pairs. How would you address the anomalous result?
