Try and link it to something that you can remember easily. For example for food tests

Biuret and Benedict’s both start with B and they are both initially blue

For a positive test, Benedict’s turns green, orange or brick red (ie traffic light colours!)

Sudan (II) is used for lipids and you add III/3 drops of it

Don’t worry about the very detailed specifics about food tests ie the volumes you need. The most important thing is the positive and negative test results
