As temperature increases, Kw...

• will also increase and the reaction will shift to form more product.

• will decrease and the reaction will shift to form more reactant.

• will remain constant and the reaction will not shift.

• will increase but the reaction will not shift.

Weak acid

• an acid that ionizes only partially in dilute aqueous solution (ie acetic acid or HF)

• an acid that completely ionizes in solution (ie hydrochloric acid)

• a substance that does not release hydrogen ions in solution

• a strong base that reacts with acids

pH + pOH =

• 12

• 14

• 16

• 10

buffer solution

• a solution made from a strong acid and its conjugate base that neutralizes small amounts of acids or bases added to it

• a solution made from a weak acid and its conjugate base that neutralizes small amounts of acids or bases added to it

• a solution that cannot resist changes in pH when acids or bases are added

• a solution made from a weak base and its conjugate acid that neutralizes large amounts of acids or bases added to it

Henderson-Hasselbalch equation

• pH = pKa + log [A^-]/[HA]

• pH = pKa - log [A^-]/[HA]

• pH = log [A^-]/[HA] + pKa

• pH = pKa + log [HA]/[A^-]
