Set up conditions before adding the solute to the water and compare the dissolution times. The timer automatically starts when the solute is added and stops when the solute is fully dissolved.

Learning objectives

This lab will allow you to investigate how the factors of temperature, agitation, and surface area influence the rate of dissolution of soluble solids in water.

Real world application

You may often desire to make solutions in your home or in the lab. Knowing how the factors of temperature, agitation, and surface area influence the rate of dissolution will save you time when preparing your favorite flavored beverage or solutions for a lab.
