Solute: The substance being dissolved into the solution. Also the substance of smaller amount. Solvent: the substance in which the solute is dissolved into. This is found in a higher quantity than the solute.

The reactant that is completely consumed leaving excess of all other reactants is the limiting reagent.
What is a limiting reagent?
200
Unsaturated: there is not enough solute to fully mix with the solvent. Saturated: the solvent can hold no more solute. Supersaturated: the solvent has more solute than it can normally hold suspended in it due to it being saturated at a higher temperature, then cooling down.
What are the differences between unsaturated, saturated, and supersaturated solutions?
200
