# Quiz | The Properties of Acids and Bases

1

A base is converted to its conjugate acid by …

A conjugate acid-base pair HA/A- differ only by the presence or absence of a proton
An acid donates a proton H+ to a base ⇒ a base is converted to its conjugate acid by adding a proton

2

How is a solution with a pH = 8?

pH > 7 ⇒ Basic solution

3

Which of the following statements is incorrect?

In a neutral solution: [H3O+] = [HO-] = 1.0 x 10-7 M

4

What is the equation of the self-ionization of water?

5

What is [H3O+] of a solution with a pOH = 11?

pH + pOH = 14 ⇒ a solution with a pOH = 11 has a pH = 3
[H3O+] = 10-pH ⇒ [H3O+] = 1.0 x 10-3 M

6

How is called a substance that can act as either an acid or a base?

Amphoteric compound: compound that can act as both a Bronsted acid and base
Polyprotic acid: acid that donate more than one acidic proton
