Unformatted text preview: conjugate acid‐base pairs. • Recognize hydronium ion, H3O+ = H+ + H2O • Know the strong acids: HCl, HBr, HI, HNO3, HClO3, HClO4, H2SO4. • Know the common strong bases: LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2. • Recognize strong acids and strong bases dissociate or ionize (break up) completely. Equilibrium lies far to the right. HNO3(aq) H+(aq) + NO3 (aq) Ca(OH)2(aq) Ca+2(aq) + 2 OH (aq) and for H2SO4: H2SO4(aq) H+(aq) + HSO4 (aq) • Recognize weak acids dissociate or ionize (break up) only to a small degree. Equilibrium lies far to the left. HF(aq) H+(aq) + F (aq) CHEM 162 Exam 1 Review – Winter2013 • Write balanced equations and equilibrium expressions for the dissociation of any acid. – Omit pure liquids and solids. HA(aq) H+(aq) + A(aq) Ka = [H+ ] [A ‐ ]
[HA] • Recognize the strength of an acid is inversely related to the strength of its conjugate base. Strong acids have conjugate bases that are weaker than H2O. Weak acids have conjugate bases that are stronger than H2O. Be able to write the net ionic equation for the conjug...
