Hydrolysis of Salts Quiz An introductory quiz on Hydrolysis In order for ionic compounds to undergo hydrolysis, the cation or anion should be a strong conjugate acid or strong conjugate base True False If the hydrogen ion from an acid is replaced by a metal, the compound obtained is called the salt of this acid. True False The salt of HCl is NaCl True False Negative ions are bases or conjugate bases True False Ammonium chloride NH4Cl when dissolved in water will cause the pH to increase. True False In order to break starch (C6H10O5)n to form glucose (C6H12O6) units, starch needs to be Hydrolyzed Polymerized Condensed Oxidized KC2H3O4 when dissolved in water will increase the pH of the solution. False True Which among the following is a strong conjugate base? ClO4- Br– CN– Cl- Na2SO4 when dissolved will cause a change in pH to the solution False True Hydrolysis cannot be carried out without ____ Water Amino acids Peptides Mitochondria C2H3O2–(aq)+ H2O ⇌ HC2H3O2 + OH– This equation represents the hydrolysis of the acetate ions True False 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 No change in pH Not enough information is available Solution will be basic 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 Kb Ka Ksp Kc The conjugate bases of strong acids are considered to be weak conjugate bases True False Loading … Question 1 of 14 Share this:TweetWhatsAppLike this:Like Loading...
