My project deals with how ionic and covalent bonds affect solubility. However, none of this would be possible without the discovery of all of those concepts in the first place.

Solubility is quite obvious to witness, and there is no person credited with the discovery of it. There are though, laws that were created based off of it, such as Henry's Law, where the amount of a given gas dissolved in a given volume of a given liquid is directly proportional to the partial pressure of that gas at equilibrium with that liquid. However, this law, as well as the other credited ones, are not used as background information for my project. The main idea behind my project was that "like dissolves like," a principle of solubility that is also uncredited. As it says in its name, it states that similar types of bonds dissolve in each other, and that they don't dissolve in the opposite ones. So based off of that, polar covalent bonds dissolve in other polar bonds, but not in non polar bonds.

The different types of bonds that I used in my experiment were ionic, polar covalent, and non polar covalent. The ionic bond was discovered

by Svante Arrhenius (1859-1927). He said that acids, bases, and salts become ions when dissolved in water. The covalent bond was discovered by Gilbert Lewis (1875-1946). He suggested a theory that said that atoms share pairs of electrons, and used this to create the Lewis Structures. This idea was taken and later became the definiton of a covalent bond.
