Q

What ions are produced when ACIDS dissolve in water to form an aqueous solution?

A

HYDROGEN IONS (+H)

18
Q

What ions are produced when ALKALIS dissolve in water to form an aqueous solution?

A

HYDROXIDE IONS (OH-)

19
Q

What is neutralisation?

A

Reaction in which acidity or alkalinity is removed

20
Q

What happens when an alkali is added to an acid?

A

pH of mixture rises as alkali reacts forming NEUTRAL SOLUTION.

21
Q

What happens when an acid is added to an alkali?

A

pH of mixture falls as acid reacts forming NEUTRAL SOLUTION

22
Q

Equation for neutralisation reaction involving acid and a base

A

acid + base —> salt + waterW

23
Q

What happens when ions of acids and alkali react?

A

H+ and OH- ions react, FORM WATER (NEUTRAL SOLUTION)

24
Q

What happens when acids react (in terms of electrons)

A

Lose electrons to form POSITIVELY CHARGED ions (H+)

25
Q

What happens when bases react (in terms of electrons)

A

Gain electrons to form NEGATIVELY HYDROXIDE ions (OH-)

26
Q

Why are acids proton _____?

A

PROTON DONORS: produce protons (these H+ ions make solution acidic)

27
Q

Why are bases _____?

A

PROTPN ACCEPTORS: produce OH- ions which accept protons, (these OH- ions make solution alkaline)

28
Q

What metals will react with acids?
