  1. Chapter 4 Unit Test Review Solutions

  2. Rules: • Lab Table Teams 1-6 • One representative from each lab table will come to a buzzer to receive a question on the board • Each correct response results in 1 point

  3. Rules Continued: • Incorrect answer: Same question goes to any other person remaining that did not buzz in before - awarded 1 point • Next question will go to another set of lab table representatives • Outside talking amongst lab tables during a round results in deduction of point

  4. Rules Continued: • Allow me to read the question fully before responding • First response - only response (cannot change answer)

  5. Question #1 • A homogenous mixture that is the same throughout is referred to as a what?

  6. Question #2 • A substance that is dissolved to make a solution is called a what?

  7. Question #3 • The substance that dissolves the solute is called a what?

  22. Question #18 • How is a saturated solution different from a supersaturated solution? • Bonus point = how are they the same?

  23. Question #19 • The solubility of a solute in a solvent always depends on both the solute’s and the solvent’s what?

  24. Question #20 • All acids, strong or weak, release what ion when dissolved in water?

  25. Question #21 • All bases, strong or weak, release what ion when dissolved in water?

  26. Question #22 • What type of reaction occurs when you add an acid and a base of equal strength together?

  27. Question #23 • What are the 2 products that always results from a neutralization reaction?
