Problem
A flask containing dilute hydrochloric acid was placed on a digital balance. An excess of limestone chippings was added to this acid, a plug of cotton wool was placed in the neck of the flask, and the initial mass was recorded. The mass of the apparatus was recorded every two minutes. At the end of the experiment, the loss in mass of the apparatus was calculated and the following results were obtained.| Time/min | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 |
|---|---|---|---|---|---|---|---|---|---|
| Loss in mass/g | 0 | 2.1 | 3.0 | 3.1 | 3.6 | 3.8 | 4.0 | 4.0 | 4.0 |
