1. Vocabulary Dilution Concentrated Solute Solvent solution solutions ppm

2. Solution = Solute + Solvent One of them is called the solute. A solute is the substance to be dissolved (sugar). The other is a solvent. The solvent is the one doing the dissolving (water). As a rule of thumb, there is usually more solvent than solute.

3. Dilute To make thinner or less concentrated by adding a liquid such as water

4. Concentration

5. Which is more concentrated? (more solute)

6. How could you increase the concentration of a solution?

7. . To concentrate a solution, one must add more solute (for example, alcohol), or reduce the amount of solvent (for example, water). By contrast, to dilute a solution, one must add more solvent, or reduce the amount of solute.solutesolvent

8. What does 10% concentration of food dye mean?

9. What does 10% solution of food coloring mean?

10. How would you make a 1000 ml of a 10% solution of food coloring? 1 part out of 10 would be food coloring. 100 ml of food coloring + 900 ml of water = 1000 ml of solution 100/1000 = food coloring = 1/10 = 10%
