Concentration
Mix chemicals with water and watch the solution change color as its concentration increases. Experiment with volume and solute to see how concentrated you can make your solution before it becomes saturated!

In Concentration, explore the relationship between solute, volume, and solution concentration. Watch as the solution changes color with increasing concentration and predict how adding or removing water, solute, or solution affects the concentration. Design your own procedures to create solutions of specific concentrations or adjust existing ones. Test how far you can go before reaching saturation, and experiment with different actions to see how they impact the concentration levels of your solutions!
