Plastic that dissolves in water.
Rule 2: Like dissolves Like… this is one of the universal axioms that holds our universe together. Greasy things are solvated by greasy things, polar things are dissolved by polar things. Think oil and water, they don’t really dissolve each other, they create an emulsion. Where does your polymer lie on the greasy to polar spectrum.
Plastic that dissolves in water. Inorganic waste represents a fundamental problem: it does not degrade easily in nature. If we know how long it takes for some of the materials we throw away every day to disappear, we will better understand the importance of recycling them.

1 Answer. As you note, there are some general rules about solubility. For example, acetone is a highly polar organic molecule, so it's not surprising it has high solubility/mixibility in water. The "like dissolves like" rule is generally based on polarity and size/shape considerations, and it's a fairly good rule.Hi, Thanks for reading this!
