Question

Which two compounds are classified as bases by the Brønsted-Lowry definition, but not by the Arrhenius definition, and why?

a
Ammonia (NH3) and boron trifluoride (BF3), because they form a compound through the transfer of an electron pair.

b
Sodium hydroxide (NaOH) and potassium hydroxide (KOH), because they dissociate to form hydroxide ions, not hydrogen ions.

c
Ammonia (NH3) and sodium carbonate (Na2CO3), because they accept hydrogen ions but lack hydroxide ions.

d
Ammonia (NH3) and methane (CH4) because they contain hydrogen but do not dissociate to form hydrogen ions.

Answer 1

Answer: Ammonia (NH3) and sodium carbonate (Na2CO3), because they accept hydrogen ions but lack hydroxide ions.
