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)
