How does Brønsted-Lowry theory relate to Arrhenius theory?

It builds upon and extends Arrhenius

What is the most significant limitation of Arrhenius theory?

It's restricted to aqueous solutions

In HCl(g)+NH3(g)→NH4Cl(s)\text{HCl}_{(g)} + \text{NH}_{3(g)} \rightarrow \text{NH}_4\text{Cl}_{(s)}, why can't Arrhenius explain this?

No water is present

How does Brønsted-Lowry theory define bases?

Proton acceptors

Why does NH3\text{NH}_3 create a problem for Arrhenius theory?

It acts as a base but has no OH−\text{OH}^-

How does Brønsted-Lowry classify CO32−\text{CO}_3^{2-} and HCO3−\text{HCO}_3^- ions?

As bases

Which theory explicitly recognises hydronium ions (H3O+\text{H}_3\text{O}^+)?

Only Brønsted-Lowry theory

What are amphoteric substances?

Can act as both acid and base

Which substance is described as amphoteric in the note?

Water

Where can Brønsted-Lowry theory be applied?

Anywhere proton transfer occurs

Which theory can explain more acid-base reactions?

Brønsted-Lowry

What does Arrhenius theory require bases to produce in water?

Hydroxide ions
