 Study Guide:  Acids and Bases

"I do not feel obliged to believe that the same God who has endowed us
with sense, reason, and intellect has intended us to forgo their use."
Galileo Galilei

  Students should be able to...

  • Know properties of acids and bases

  • Know definitions of acids and bases according to Arrhenius, Bronsted-Lowry, and Lewis.

  • Identify polyprotic acids and bases.

  • Review naming of acids, both binary and ternary.

  • Calculate pH, pOH, H+ concentration, and OH- concentration given any one.

  • Calculate the solute and solvent necessary for a dilution

  • Calculate the volume necessary to neutralize an acid/base

  • Measure the pH and acidity/alkalinity of household chemicals (laboratory)

  • Calculate the % by mass of acetic acid in vinegar (laboratory)

  • Calculate the neutralizing power of common antacids (laboratory)

    Review problems

    1. List three properties of acids.
    2. List three properties of bases.

    Fill in the table concerning definitions of acids and bases.

    Definition
    Acid
    Base
    Traditional (Arrhenius)    
      Electron pair acceptor  
        Proton acceptor

    Name the following acids. Circle any polyprotic acids.

    Titrations

    18. A 25.0 ml sample of vinegar requires 28.33 mL of a 0.953 M solution of NaOH for titration to the equivalence point. What mass in g of acetic acid is in the vinegar sample, and what is the concentration of acetic acid in vinegar?


    Dilutions

    19. How much water and how much 12 M HCl must be used to prepare 500 ml of a 1 M HCl solution?
