Do all Substances Dissolve?
Dissolving is the process in which a solute's bonds are broken apart by a solvent (Ducksters, 2019)
Solute
A solute is a substance that can be dissolved in a solvent and can be in a gas, liquid or solid form (BD Editors, 2016)
Examples of solutes: Salt, sugar, oxygen, quinine, carbon dioxide
What makes a good solute?
A good solute will be soluble and is going to be most soluble when both the solvent and solute have similar molecular properties, if the molecules of the solute are smaller than that of the solvent
Molecular properties such as polarity
Why does molecular size matter?
Because the bigger molecules of the solvent the easier the solute is to be dissolved
Solvent
A solvent is a substance that dissolves a solute and breaks apart the molecules of a solute
The universal solvent is water due to its polarity and likeliness to form hydrogen bonds (Khan Academy, n.d.)
Bonds
Does bond polarity effect the solute's ability to dissolve
Yes if water is the solvent a polar solute is needed and if there is a non polar solvent a non polar solute is needed (like dissolves like)
bond polarity
hydrogen bonds
Ion dipole
Factors that effect solubility
Temperature
Pressure
Molecular size
