Dilution should include

• defining solute and solvent
• reading and analyzing the directions
• describing how to calculate and prepare a dilution in terms of the relationship between solute and solvent (e.g., 1:3)
• calculating amounts for dilutions
• preparing diluted solutions according to directions with 100-percent accuracy and appropriate safety precautions. 

Process/Skill Questions:

• Why is it important to follow the manufacturer’s directions for dilution of a product?
• Why is 100 percent accuracy necessary when preparing diluted solutions?
• How would one prepare a dilution to a 9:1 ratio?
• What would be the steps for preparing one quart of instrument milk, using the 1:6 dilution ratio?
