  1. Review Game Eureeka Time • Get a board • Calcium carbonate cylinder • Wipey thing • Partner • If viewing on the internet: • Get a pencil and paper and attempt to answer the questions first . . . that is why its called review . . . • If you put a signed piece of paper in the top shelf of papers to grade which says “MungaDinga Lunchbox” you will receive extra credit on the exam

  2. 1. Which of the following is the best conductor of electricity? NaCl (s) NaCl (aq) C6H12O6 (s) C6H12O6 (aq)

  3. NaCl (aq)

  4. 2. Which solution is the best conductor of electricity? • 0.1 M HNO3 • 0.1 M CH3COOH • 0.1 M C6H12O6 • 0.1 M C2H5OH

  5. 3. What happens to the conductivity of a solution if KCl is added to a saturated solution of KCl? nothing

  6. 4. In a 0.01 M solution of HCl, blue litmus will do what? turn red

  7. 5. In the below reaction, which quantity would be considered the proton doner? HF + H2O  H3O+ + F-

  8. 6. The conjugate base of NH3 is • NO2- • NO3- • NH2- • NH3

  9. 7. A 0.1 M acid solution at 298 K would conduct electricity best if the acid had a Ka value • 1 x 10-7 • 1.7 x 10-2 • 6.6 x 10-4 • 1.8 x 10-5

  10. Pure water is similar to 1.0 M HCl in that they both • Contain H3O+ • Are neutral to litmus • Have a pH higher than 7 • Are good conductors of electricity

  11. According to the Bronsted-Lowry theory, an acid is any species that can . . . Donate protons (H+)

  12. When tested, a solution turns red litmus to blue. This indicates that the solution contains two types of ion. Which ion is more abundant? OH-

  13. What will water become if it acts as a base? H3O+

  14. 12. In the reaction below is water an acid, a base, or both? • H2O + H2O  H3O+ + OH- BOTH

  15. Which salt will hydrolyze in water to create a basic solution? What does this mean? React each with water . . If the product is a strong base and a weak acid, it will be a basic solution. • NaNO2 • CaCl2 • BaI2 • MgSO4 NaNO2 + H2O  NaOH + HNO2

  16. How many mL of 1.0 M H2SO4 are needed to exactly neutralize 15 mL of 2.0 M Ba(OH)2? Note the mole ratio is 2:2 30-mL

  17. As 50-mL of 0.1 M HCl is added to 100-mL of 0.1-M NaOH, the pH of the NaOH will do what?

  18. 16. Write a chemical equation that would represent a neutralization reaction.

  19. A water solution contains 0.50 moles of HCl. How many moles KOH should be needed to neutralize the acid? • How many grams does that represent? 0.50 moles 28.5-g

  20. 18. What is the pH of a solution if the HYDROXIDE ion concentration is 1 x 10-4 moles per liter? 10

  21. What is the [H3O+] of a 0.001 M HCl solution? 1.0 x 10-3

  22. 20. Write the Ka equation for the following reaction: • HNO2 (aq) = H+ (aq) + NO2- (aq)

  23. You find an unknown solution in the lab • What characteristics will it have if it is a base? • What characteristics will it have if it is an acid?

  24. 22. What materials will you need if you are going to do titration to see what the concentration of the chemical is? The chemical turns methyl orange a dark red color.
