Solutions lab: Complete the analysis questions to the lab.

TYPES OF SOLUTIONS: Read the entire laboratory investigation and the relevant pages of your textbook. Then answer the questions that follow.

  1. Use your text book to define the following terms:

a)dilute solution

b)concentrated solution

c)unsaturated solution

d)saturated solution

e)supersaturated solution

  1. You have a pair of dark blue jeans that you would like to lighten. Compare the effect of adding a capful of bleach to the wash water versus actually pouring a

capful of bleach directly on to your jeans.

  1. You are given a sponge and a cup of water. How would you demonstrate an unsaturated, saturated, and supersaturated condition?
  1. What is a seed crystal? When is a seed crystal used?

SOLUTIONS – TERMS: Use the following website to complete the following:

pages 3 - 9

A solution consists of two parts, the (1)______, which is the substance dissolved and the (2)______, which is the substance that does the dissolving. A solution is a (3)______mixture in which the solute is distributed (4)______throughout the solvent. Ionic compounds dissolve readily in water because the ions (5)______. This occurs because both cations and anions are attracted to water molecules. The ions are attracted to water molecules because water is a (6)______substance. When an individual ion is surrounded by water molecules that ion is called (7)______ion. (The more general term of (8)______is used when the the solvent is not water.) Many substances dissolve in water, therefore it is called the (9)“______” solvent. Two liquids, alcohol and water will mix nearly 100% in each other, therefore we say that these substances are (10)______. However, oil and water are (11)______. Similarly, (12)______substances do not dissolve appreciably in water. Also, polar compounds have a low (13)______in nonpolar solvents. Generally, three methods of increasing the solubility of a solid solute are increasing (14)______, (15)______, and (16)______. These methods would have the opposite effect on a (17)______solute in a liquid solvent. A dissolved solute that can conduct an electrical charge is known as a(n) (18)______. Dissolved (19)______compounds and (20)______acids are examples of these. A mixture of two or more metals is known as a(n) (21)______. A solution that contains the maximum amount of solute at a given temperature is known as a(n) (22)______solution. A solution that contains less than the maximum amount of solute is (23)______and if it contains more than the maximum it is (24)______. A (25)______solution will typically have a small amount of solute at the bottom of its container. A solid solute that falls out of solution is called a (26)______.
