Hydrolysis of Salts Quiz An introductory quiz on Hydrolysis In order to break starch (C6H10O5)n to form glucose (C6H12O6) units, starch needs to be Oxidized Condensed Polymerized 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 C2H3O2–(aq)+ H2O ⇌ HC2H3O2 + OH– This equation represents the hydrolysis of the acetate ions False True Hydrolysis cannot be carried out without ____ Peptides Water Amino acids Mitochondria 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 Kb Kc Ka Which among the following is a strong conjugate base? Cl- ClO4- Br– CN– In order for ionic compounds to undergo hydrolysis, the cation or anion should be a strong conjugate acid or strong conjugate base True False The conjugate bases of strong acids are considered to be weak conjugate bases False True The salt of HCl is NaCl True False Na2SO4 when dissolved will cause a change in pH to the solution False True Negative ions are bases or conjugate bases False True KC2H3O4 when dissolved in water will increase the pH of the solution. 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 acidic Not enough information is available No change in pH Solution will be basic Ammonium chloride NH4Cl when dissolved in water will cause the pH to increase.
