To use indicators to test various substances
around home to see if they are acids or bases.
Aim:
To use indicators to test various substances around the home to see if they are acids
or bases.
Method:
1. Set up your spotting tile with 12 substances from your teacher.
(Use just two drops for any liquid and add two drops of water to the solids before
you test them eg soap powder)
2.Add a single drop of universal indicator to each of the substances.
Put a photo of your completed spotting tile here:
Results:
Draw a table which lets you display your results clearly. The table should include
the name of the substance, the colour with universal indicator and whether it is
acids or base and how strong it is.
Conclusion:
(Look at the aim of the experiment and write a short conclusion which responds to the aim)
