Microscale indicators

A microscale, dropp reaction loking at a few common indicators and their colour changes

 

Neutralisation to make a salt

Reaction of of sulphuric acid with copper oxide to make copper sulphate.

 

Microscale titration

A microscale version of an acid-base titration.

 

Sulphuric acid reaction with sugar.

A striking demonstration – resulting from the powerful dehydration effect of the sulphuric acid.
