But to chemists solutions are things that are still all mixed up. If an experiment works, something has gone wrong. When you don't know what you're doing, do it neatly. Experiments must be reproducible, they should fail the same way each time. First draw your curves, then plot your data.
Experience is directly proportional to equipment ruined.
Always keep a record of your data. It indicates that you have been working. To do a lab really well, have your report done well in advance. If you can't get the answer in the usual manner, start at the answer and derive the question. In case of doubt, make it sound convincing.
