Understanding Concepts
How does increasing the temperature of a solvent affect the solubility of a gas?
Explain why the temperature of water might increase when a solution forms.
Explain why crushing a solute increases the rate of solution.
Name and describe the three types of solutions.
Explain why oil does not dissolve in water.
Describe how you might increase the solubility of a solid in a liquid.
Explain how a solution can be both dilute and saturated.
Describe three different ways in which the concentration of a solution can be reported.
Define and give an example of an acid and of a base.
List the properties of acids and bases. Which of the properties would you use to safely test whether an unknown substance was an acid or a base?
If you add hydrochloric acid (HCl) to magnesium (Mg) metal, what will you observe? What products form in this reaction?
Identify each of the following compounds as an acid, base, or salt: LiOH, H2CO3, Ba(OH)2, and KCl.
What determines the strength of an acid?
What happens when a solution of nitric acid (HNO3) is added to a solution of potassium hydroxide (KOH)? What are the products?
Which of the following compounds can react with H2SO4 to form a salt: NaCl, Ca(OH)2, HF, AlCl3, H2O, Mg(OH)2? Name the salt(s) that would form.
