Unit VIII. Acid & Base Theory

PS-8 ACIDS & BASES – Acids and bases are compounds which affect the equilibrium of water in aqueous solutions, which are common to studying many chemical phenomena. Understanding how water responds to the presence of an acid or base, allows chemists to utilize this special property in most aspects of chemistry.

TS 8.1- Definitions of acids & bases. Acids and bases are compounds which affect the hydrogen ion concentrations in aqueous solutions.

   8.1.1 Describe acids and bases as substances that affect hydronium and hydroxide ions in aqueous solutions.

   8.1.2 Determine names for inorganic acids given chemical formulas

   8.1.3 Describe physical and chemical properties of acids & bases in aqueous solutions

   8.1.4 Determine if a substance is acidic, basic, or neutral based on the pH scale and/or chemical indicators

   8.1.5 Explain the self-ionization of water as a function of acid/base theory

   8.1.6 Calculate the pH and/or the pOH of a solution given the concentration of hydronium or hydroxides in solution

   8.1.7 Recognize applications of acid-base reactions

TS 8.2 – Strong vs weak acids/bases. The strength of an acid or base is based on its ability to self-ionize or dissociate in solution.

   8.2.1 Differentiate strong vs. weak acids/bases in relation to relative ionization/dissociation

TS 8.3 Titrations. The concentration of an unknown acid (or base) can be determined experimentally through neutralization reactions with known solutions.

  8.3.1 Describe the role of chemical indicators play in acid/base titrations

  8.3.2 Quantitatively describe a titration of a strong acid and a strong base and relate the titration curve to chemical events

  8.3.3 Compare a titration curve of a strong vs. a weak acid or base
