7 Does the dissolving Usually a liquid Generally in the greatest quantity. Gets dissolved Usually a solid Generally in the smallest quantity.

8 Hypertonic: solute is in greater concentration compared to another solution. Hypotonic: solute is in lower concentration compared to another solution. Isotonic: solute is in equal concentration compared to another solution.
