Definitions

Question 1

What is the ionic product of water?

Answer 1

Kw = Kc[H2O] = [H+][OH-]

Question 2

Define pH

Answer 2

The pH of a solution is the negative logarithm to the base 10 of the hydrogen ion concentration measured in moles per litre

Question 3

What is the Bronston Lowry theory of definition a strong acid?

Answer 3

A strong acid is a good proton donor

Question 4

What is the Bronston Lowry theory definition of a weak acid?

Answer 4

A weak acid is a poor proton donor

Question 5

What is the acid dissociation constant?

Answer 5

Ka = [H+][A-] over [HA]

Question 6

What is the Bronston Lowry definition of a strong base?

Answer 6

A strong base is a good proton acceptor

Question 7

What is the Bronston Lowry definition of a weak base?

Answer 7

A weak base is a poor proton acceptor

Question 8

What type of conjugate base does a strong acid?

Answer 8

A strong acid has a weak conjugate base

Question 9

What type of conjugate base does a weak acid have?

Answer 9

A weak acid has a strong conjugate base

Question 10

What does pH + pOH equal?

Answer 10

14

Question 11

Define pOH

Answer 11

pOH = -log to the base ten [OH-]

Question 12

What is the equation for the pH of solution?

Answer 12

[H+] = the square root of Ka x M acid

M acid is the concentration of the acid in moles per litre

Question 13

What is the equation for the pOH of a solution?

Answer 13

[OH+] = the square root of Kb x M base

M base is the concentration of the base in moles per litre

Question 14

What is an acid-base indicator?

Answer 14

A substance that changes colour according to the pH of the solution in which it is placed

Question 15

What is the range of an indicator?

Answer 15

The range of an indicator is the pH interval over which there is a clear change of colour for that indicator
