Section 1
What is a Solution?
Explain why a suspension is considered a heterogeneous mixture.
Classify the following mixtures as homogeneous or heterogeneous: $$\begin{array}{ll}{\text { a. lemon juice }} & {\text { c. blood }} \\ {\text { b. tap water }} & {\text { d. house paint }}\end{array}$$
In a solution, which component is considered the solvent? Which is the solute?
Name the solvent and solute(s) in the following solutions: $$\begin{array}{ll}{\text { a. carbonated water }} & {\text { c. coffee }} \\ {\text { b. apple juice }} & {\text { d. salt water }}\end{array}$$
Does a solution have to involve a liquid? Explain your answer.
How is a colloid distinguished from a solution or a suspension?
What is the basic physical principle that chromatography is based upon?
How can distillation be used to prepare pure water from tap water?
Explain how you could determine that brass is a solution, and not a colloid or suspension.
Explain why fog is a colloid.
You get a stain on a table cloth. Soapy water will not take the stain out, but rubbing alcohol will. How does this relate to chromatography?
If you allow a container of sea water to sit in the sun, the liquid level gets lower and lower, and finally crystals appear. What is happening?
