Like Dissolves Like

HELLLLLLLLLLO..ugh.


To DISSOLVE is when a chemical spreads evenly into another chemical.

A SOLUTE gets dissolved.

A SOLVENT does the dissolving.

"like dissolves like" is an expression used by chemists to remember how some solvents work. It refers to "polar" and "nonpolar" solvents and solutes. This means that substances are more likely to dissolve in other substances with similar chemical properties. polar solutes dissolve in polar solvents. Nonpolar solutes dissolve in nonpolar solvents.




example: Water (H2O) is polar. Oil is non polar. Water (H2O) will not dissolve oil. Water (H2O) is polar. Salt (NaCl) is polar. Like dissolves like so polar dissolves polar so water dissolves salt.
