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