2
Q
What happens to the pH of an acid when it is diluted?
A
The pH increases until 7
3
Q
Is dilution a neutralisation reaction?
A
No because a neutralisation makes a salt and water
4
Q
Why does the pH not go higher than 7 in a dilution reaction?
A
Only a base has a pH higher than 7, water has a pH of 7
5
Q
Why is dilution a safer way of neutralising an acid rather than doing a neutralisation reaction?
A
Bases can be just as hazardous as the acid we are treating.
