Q

Define an Acid.

A

An Acid is a proton donor, it releases H+ ions when added to water and produces a pH lower than 7.

25
Q

What is a proton acceptor?

A

A base

26
Q

What is a base?

A

A proton acceptor that can neutralise an acid

27
Q

What is an Alkali?

A

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

28
Q

What is NaOH?

A

Sodium Hydroxide

29
Q

What is the formula for Sodium Hydroxide?

A

NaOh

30
Q

What is KOH?

A

Potassium Hydroxide

31
Q

What is the formula for Potassium Hydroxide?

A

KOH

32
Q

Is ammonia an alkali?

A

Ammonia is an Alkali

33
Q

What is Sodium hydroxide used for?

A

Oven cleaners and paint strippers

34
Q

Why is water produced in a neutralisation reaction?

A

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

35
Q

Is Ammonia a weak or strong base?

A

It is a weak base

36
Q

How do we know the strength of Ammonia?

A

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

37
Q

Name a weak base.

A

Ammonia (NH3)

38
Q

Name three biological Acids.

A

Fatty Acids
Amino Acids
Nucleic Acids

39
Q

What does amphotenic mean?

A
