Q

What does Arrhenius’ conclusions explain

A

Why strong acids only conduct in aqueous solution, why weak acids do not conduct well, Acids need water before they show their acidic properties

Q

Limitations of Arrhenius’ conclusions

A

Limited to reactions in water, when acid dissolves in water H30+ is formed rather than a hydrogen ion, does not explain why substances can be an acid and a base

Poor proton donor

19
Q

What is a strong Base according to Bronsted-Lowry

A

A good proton acceptor

20
Q

What is a weak base according to Bronsted-Lowry

A

A poor proton acceptor

21
Q

What is an amphoteric substance

A

One which can react as an acid with a base and a base with an acid.

22
Q

Advantages of the Bronsted-Lowry theory

A

Shows how hydronium is formed when acids and bases react, allows for acids that can react without the presence of water, explains how an acid can be amphoteric
