Making Indicators

Aim To make acid-base indicators using tea

Equipment
Beaker
Bunsen burner
Tripod
Gauze mat
Three bags of tea
Fireproof mat

Method

Put 100ml of water into a beaker and boil.
Turn off the bunsen burner and put three tea bags in the beaker.
Remove the tea bags when the tea is very strong
Place in a small beaker and leave to one side






In science yesterday my class were making indicators from different vegetables and tea bags me and my buddy luke were doing the tea bags and the rest of the class were doing the other things.

Our tea bag changed different colors from dark brown to light brown the chemicals we used to change the colors were hydrochloric acid and sodium hydroxide. The hydrochloric acid made the tea dark brown and the sodium hydroxide made the tea light brown

Conclusion

Our conclusion was to change the color of the tea dark and light we did not succeed because the color was meant to be yellow I think we added too much hydrochloric acid to the tea.
