18
Q

Sulphuric acid + sodium hydroxide>

19
Q

When creating a sulphate why do we put on excess salt?

A

To ensure that all the acid has been neutralised

20
Q

How do you know when the reaction has stopped

A

There is no more effervescence

21
Q

When there is no solid how do you obtain a solution

A

Titration using a bursts to measure the exact amount of acid added to the alkali

22
Q
