Quick question. Which one has more freezing point depression, Table salt or rock salt?
Thanks
Rock salt. The larger salt particles will separate the water molecules so they cannot freeze together as well. You want to have the energy from the ice cream mix transferred to the salt particles so larger particles will be better.

The rules have most of the topics, but sometimes tests have other components. The test
should be about dairy and dairy products, but I have found that some organic chemistry can get involved. Make sure you know the basic stuff like carbohydrates, fats (fatty acids mainly), and sterols.

Kind of both, leaning a little more towards dairy chemistry. Most of the criteria on the rules cover what has been on the tests (there are a lot of topics haha).
