Bronsted-Lowry Theory of Acids and Bases

Question 1

Define the Brønsted–Lowry definition of an acid

Answer 1

Brønsted–Lowry definition: an acid is a proton donor

Question 2

Define the Brønsted–Lowry definition of a base

Answer 2

Brønsted–Lowry definition: a base is a proton acceptor

Question 3

Define the Brønsted–Lowry definitions of the following: 
strong acid
weak acid 
strong base 
weak base

Answer 3

Brønsted–Lowry definitions:
A strong acid is a good proton donor.
A weak acid is a poor proton donor.
A strong base is a good proton acceptor.
A weak base is a poor proton acceptor.

Question 4

Is water an acid or a base?

Answer 4

Water can act as either an acid or a base.

Question 5

What are substances that can act as both acids and bases called?

Answer 5

amphoteric or amphiprotic

Question 6

What are substances that are amphoteric or amphiprotic labelled to be?

Answer 6

They can donate or accept protons, they can act as either acids or bases.

Question 7

What can the Bronsted-Lowry theory of acids and bases be applied to?

Answer 7

To acid-base reactions that do not involve water as the solvent

Question 8

What is important to note about acid-base reactions when it comes to donating or accepting protons?

Answer 8

An acid will only donate a proton id there is something else present to accept this proton.
A base can only accept a proton if there is something present to donate the proton.
