neutralisation

 1. take a test tube rack with 1 boiling tube each end of the rack and 4 test tubes.

2. half fill the boiling tube at one end with sodium hydroxide 

3. half fill the boliing tube at the other end with hydrochloricacid 

4. fill each test with 5 drops of universal indicttor 

5. using the pipettes you will add dorps of the acid or alkaline to the test tubes to make colours of ,red, ,orange, ,yellow, ,green, ,blue, ,violet,

Equipment:

• Universal Indicator

• 1 M HCl ( Hydrochloric Acid)

• 1 M NaOH (Sodium Hydroxide)
