Hydrolysis of Salts Quiz An introductory quiz on Hydrolysis 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 Ksp Ka Kb Kc Na2SO4 when dissolved will cause a change in pH to the solution False True KC2H3O4 when dissolved in water will increase the pH of the solution. True False Hydrolysis cannot be carried out without ____ Mitochondria Amino acids Water Peptides In order to break starch (C6H10O5)n to form glucose (C6H12O6) units, starch needs to be Condensed Polymerized Oxidized Hydrolyzed If the hydrogen ion from an acid is replaced by a metal, the compound obtained is called the salt of this acid. False True Ammonium chloride NH4Cl when dissolved in water will cause the pH to increase. False True The conjugate bases of strong acids are considered to be weak conjugate bases False True Negative ions are bases or conjugate bases True False The salt of HCl is NaCl 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 Not enough information is available Solution will be basic No change in pH Solution will be acidic In order for ionic compounds to undergo hydrolysis, the cation or anion should be a strong conjugate acid or strong conjugate base True False C2H3O2–(aq)+ H2O ⇌ HC2H3O2 + OH– This equation represents the hydrolysis of the acetate ions True False Which among the following is a strong conjugate base?
