學習目標

• Describe the relationships between volume and amount of solute to solution concentration
• Explain qualitatively the relationship between solution color and concentration
• Predict and explain how solution concentration will change for adding or removing: water, solute, and/or solution
• Calculate the concentration of solutions in units of molarity (mol/L)
• Design a procedure for creating a solution of a given concentration
• Identify when a solution is saturated and predict how concentration will change for adding or removing: water, solute, and/or solution
• Describe the relationship between the solution concentration and the intensity of light that is absorbed/transmitted
• Describe the relationship between absorbance, molar absorptivity, path length, and concentration in Beer’s Law
• Predict how the intensity of light absorbed/transmitted will change with changes in solution type, solution concentration, container width, or light source, and explain why
