Neutralisation Reactions

Question 1

Metal oxide + acid =

Answer 1

Salt + Water

Question 2

Metal hydroxide + acid =

Answer 2

Salt + water

Question 3

Acid + Metal Carbonate =

Answer 3

Salt + Water + Carbon dioxide

Question 4

1st step of a neutralisation reaction

Answer 4

First you heat up a dilute acid using a bunsen burner then you keep adding insoluble base

Question 5

2nd step of a neutralisation reaction

Answer 5

When the base is no longer disappearing the base must be in excess and the acid would have been completely neutralised

Question 6

3rd step of a neutralisation reaction

Answer 6

We filter out the insoluble base with filter paper and filter funnel

Question 7

4th step of a neutralisation reaction

Answer 7

We evaporate off some water in our beaker and then leave it to cool causing crystals to form using filter paper then we dry the crystals somewhere warm

Question 8

Why do we warm sulfuric acid when making crystals of magnesium sulfate?

Answer 8

To speed up the reaction

Question 9

Why do we repeatedly add spatulas of magnesium oxide to a beaker and why do we stir the mixture when making crystals of magnesium sulfate?

Answer 9

So the Hydrochoric acid reacts

Question 10

Why do we filter the mixture when making crystals of magnesium sulfate?

Answer 10

To remove excess magnesium oxide
