  1. pH and Solubility Quiz Review Game 4 / 14 / 09

  2. Admit Slip • pH is the measurement of ______ ions in a solution. • It can tell us whether a solution is ______ , _______ , or _______ . • Which of the following compounds is soluble? KNO3 or PbOH

  3. Objectives • Students will be able to: • Convert between pH, pOH, [H+], and [OH-] • Predict whether an ionic compound will be soluble or insoluble • Distinguish between strong and weak acids/bases • Distinguish between Arrhenius and Bronsted-Lowry acids/bases

  4. Game Rules • Students will choose a group of up to 4 players. • Students will write all answers down on a piece of paper. No calling out. • The winning group will receive 3 bonus quiz points.

  5. Question 1 – 200 points • Acids taste _______ and have a pH between: a) 7 and 14 b) 10 and 14 c) 5 and 8 d) 0 and 7 sour

  6. Question 2 – 200 points • Bases feel _______ and have a pH between: a) 7 and 14 b) 10 and 14 c) 5 and 8 d) 0 and 7 slippery

  7. Question 3 - 200 points • Strong acids have a pH of: a) 0 to 7 b) 4 to 7 c) 0 to 4 d) 5 to 8

  8. Question 4 - 200 points • Strong bases have a pH of: a) 7 to 10 b) 10 to 14 c) 0 to 14 d) 5 to 8

  9. Question 5 - 200 points • Neutral solutions have a pH of what number? 7

  10. Question 6 - 200 points • A solution with a pH of 5 would be a: • strong acid • weak acid • strong base • weak base • neutral

  11. Question 7 - 400 points • In a neutralization reaction, an acid and a base are reacted. What are the two products of a neutralization reaction? water and a salt

  12. Question 8 - 400 points • The Arrhenius definition of an acid is that it gives off which ion? H+ hydrogen ion

  13. Question 9 - 400 points • The Arrhenius definition of a base is that it gives off which ion? OH- hydroxide ion

  14. Question 10 - 400 points • The Bronstead-Lowry definition of an acid says that it is a: • proton acceptor • proton donor • proton borrower

  15. Question 11 - 400 points • The Bronsted-Lowry definition of a base is that it is a: • proton acceptor • proton donor • proton borrower

  16. Question 12 - 200 points • What is the pH of a solution with a concentration of H+ ions [H+] of 10-5 M? 5

  17. Question 13 - 200 points • What is the pH of a solution with a concentration of H+ ions [H+] of 0.001 M? 3

  18. Question 14 - 200 points • What is the pH of a solution with a pOH of 9? 5

  22. Question 18 - 100 point bonus • How would you find the pH of a solution if the [H+] was 0.0352 M instead of something simple like 0.001 M ? pH = -log [H+] you would use the log button on your calculator

  23. Question 19 - 400 points • What is the pH of a solution with a [OH-] of 0.00001 M? 9

  24. Question 20 - 400 points • What is the [H+] of a solution with a pOH of 2? 10-12 M

  25. Question 21 - 400 points • What is the [H+] of a solution with a [OH-] of 10-3 ? 10-11 M
