Like Dissolves Like

we learned how to dissolve things!
dissolving is to break down one substance and assimilate it into another substance



its not easy to dissolve things, only like dissolves like
Like Dissolves Like is the rule for dissolving; only polar liquids can dissolve polar and nonpolar to nonpolar





the one with more substance is the solvent while the other is the solute
