Hydrolysis of Salts Quiz An introductory quiz on Hydrolysis Negative ions are bases or conjugate bases False True Which among the following is a strong conjugate base? ClO4- Br– Cl- CN– The salt of HCl is NaCl True False C2H3O2–(aq)+ H2O ⇌ HC2H3O2 + OH– This equation represents the hydrolysis of the acetate ions False True The conjugate bases of strong acids are considered to be weak conjugate bases False True If NH4C2H3O2 is dissolved in water, will the pH increase or decrease for its aqueous solution? Ka for NH4+ is 5.8×10-10. Kb for C2H3O2– is 5.6×10-10 Solution will be basic Solution will be acidic No change in pH Not enough information is available In order for ionic compounds to undergo hydrolysis, the cation or anion should be a strong conjugate acid or strong conjugate base False True If the hydrogen ion from an acid is replaced by a metal, the compound obtained is called the salt of this acid. False True In order to break starch (C6H10O5)n to form glucose (C6H12O6) units, starch needs to be Polymerized Hydrolyzed Oxidized Condensed Ammonium chloride NH4Cl when dissolved in water will cause the pH to increase. False True Na2SO4 when dissolved will cause a change in pH to the solution True False NH4+ + H2O ⇌ H3O+ + NH3 For the hydrolysis of ammonium ions shown in the above equation, if you are to write an equilibrium expression will it be Ka Kc Kb Ksp KC2H3O4 when dissolved in water will increase the pH of the solution.
