This experiment demonstrates the linear relationship between the absorbance and the concentration of a colored solution. . Lesson 16. Success Criteria. Describe and explain the effect of enzyme concentration and substrate concentration on enzyme activity. Starter. Think, pair, share. Effect of enzyme concentration on enzymes. Solution is a homogeneous mixture of two or more substances. . . Solute . is the dissolved substance. , whereas solvent . is a substance in which solutes dissolves to make the mixture. . There . are different types of solutions used in medical laboratory procedures. . Megan Beyer . KNH 304. Background . As 66% of Americans are currently overweight or obese there is a need to understand the contributing factors. There is a link between frequent fast-food consumption reflecting a high-fat diet, reduced fruit and vegetable consumption, low fiber and lower physical activity. The geographical concentration of fast-food outlets may be associated with an increase in overweight and obesity. . . Photograph: Tony Clarke, VOCALS . REx. flight RF07. Robert Wood.

Is a measure of the amount of substance (solute….usually solid) that exists in a volume of solution (solvent).. Concentration. The amount of solute in a solution.. How do we indicate how much of the electrolytes are in the drink?. Concentrated versus Dilute. solute. solvent. Lower concentration. Not as many solute (what’s being dissolved) particles. Higher concentration. Solution is a homogeneous mixture of two or more substances. . . Solute . is the dissolved substance. , whereas solvent . is a substance in which solutes dissolves to make the mixture. . There . are different types of solutions used in medical laboratory procedures. . LG: I can perform concentration calculations involving units commonly used in consumer products. Percent Concentration. Many consumer products report the percent of solute relative to the total amount of solution; these concentrations may involve weights and volumes. Introductions to Solutions!. 1. Solution:. 2. Solute. 3. Solvent. 4. Saturated:. 5. Unsaturated:. 6. Supersaturated:. 7. Electrolyte:. 8. Aqueous:. 9. Homogeneous: . 10. . Heterogeneous :. AIM# 1: How can we describe solutions?. 3.3: Molarity. Describe the fundamental properties of solutions. Calculate solution concentration using molarity.
