Unformatted text preview: – Cl- + H2O ⇌ HCl + OH- – Where does the equilibrium lie for both of these reac4ons? Anions as weak bases Anions as weak bases • Anions (A- ) are the conjugate bases of HA, so HA determines if the anion is a weak or strong base Anions as weak bases • Anions (A- ) are the conjugate bases of HA, so HA determines if the anion is a weak or strong base • A- + H2O ⇌ HA + OH- – – – – If HA is a strong acid, A- is a _____ conj base? If equil lies to the _______, the solu4on will be ____ If HA is a weak acid, A- is a _____ conj base? If equil lies to the _________, the solu4on will be ____ Anions as weak bases • Anions (A- ) are the conjugate bases of HA, so HA determines if the anion is a weak or strong base • A- + H2O ⇌ HA + OH- – – – – If HA is a strong acid, A- is a _____ conj base? If equil lies to the _______, the solu4on will be ____ If HA is a weak acid, A- is a _____ conj base? If equil lies to the _________, the solu4on will be ____ • Example: Anions as weak bases • Anions (A- ) are the conjugate bases of HA, so HA determines if the anion is a weak or strong base • A- + H2O ⇌ HA + OH- – – – – If HA is a strong acid, A- is a _____ conj base? If equil lies to the _______, the solu4on will be ____ If HA is a weak acid, A- is a _____ conj base? If equil lies to the _________, the solu4on will be ____ • Example: Cl- is the conjugate base of HCl (strong acid), so Cl- is a weak (non) conjugate base – Cl- has NO desire...
