Answer 25

A base

Question 26

What is a base?

Answer 26

A proton acceptor that can neutralise an acid

Question 27

What is an Alkali?

Answer 27

A type of base which dissolves in water and creates Hydroxide (OH-) ions and creates a solution with a pH above 7.

Question 28

What is NaOH?

Answer 28

Sodium Hydroxide

Question 29

What is the formula for Sodium Hydroxide?

Answer 29

NaOh

Question 30

What is KOH?

Answer 30

Potassium Hydroxide

Question 31

What is the formula for Potassium Hydroxide?

Answer 31

KOH

Question 32

Is ammonia an alkali?

Answer 32

Ammonia is an Alkali

Question 33

What is Sodium hydroxide used for?

Answer 33

Oven cleaners and paint strippers

Question 34

Why is water produced in a neutralisation reaction?

Answer 34

The H+ ions of the acid react with the OH- ions of the alkali and produce H2O

Question 35

Is Ammonia a weak or strong base?

Answer 35

It is a weak base

Question 36

How do we know the strength of Ammonia?

Answer 36

The reaction has an equilibrium sign because only a small amount of the NH3 will react with the water, not nearly all.

Question 37

Name a weak base.

Answer 37

Ammonia (NH3)
