Ions in Solutions

- The formation of a solution depends on the ability of the solute to dissolve in the solvent
- Solvation is the interaction between solutes and solvents
- Ionic solids (salts) are cyrstals made up of ions
- Dissolving ionic solutions produces ions in a process called disssociation

Here are 2 examples of ionization

FeCl3 (s) ----->Fe 3+ (aq) + 3 Cl -1 (aq)
(NH4)2SO4 (s) -----> 2NH4 + (aq) + SO4 2- (aq)
