Hydrolysis of Salts Quiz An introductory quiz on Hydrolysis Hydrolysis cannot be carried out without ____ Water Amino acids Peptides Mitochondria KC2H3O4 when dissolved in water will increase the pH of the solution. True False Ammonium chloride NH4Cl when dissolved in water will cause the pH to increase. 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 Ksp Kb Kc Ka In order for ionic compounds to undergo hydrolysis, the cation or anion should be a strong conjugate acid or strong conjugate base False True Negative ions are bases or conjugate bases False True The conjugate bases of strong acids are considered to be weak conjugate bases False True C2H3O2–(aq)+ H2O ⇌ HC2H3O2 + OH– This equation represents the hydrolysis of the acetate ions True False The salt of HCl is NaCl 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 Na2SO4 when dissolved will cause a change in pH to the solution False True Which among the following is a strong conjugate base? ClO4- CN– Br– Cl- 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 Solution will be basic Not enough information is available In order to break starch (C6H10O5)n to form glucose (C6H12O6) units, starch needs to be Condensed Polymerized Hydrolyzed Oxidized Loading … Question 1 of 14 Share this:TweetWhatsAppLike this:Like Loading...
