Aldehyde and ketone are organic compounds containing carbonyl group.To identify whether the carbonly compound is an aldehyde or a ketone,the Schiff's and Tollen's tests can be carried out.

Tollen's test results in the formation of silver mirror.I was excited to see the silver mirror so I volunteer to do this test!The Schiff's test results in the changes of colour of the solution from pink to purple.There is another test,Iodoform test.It is a long test so we all did it together.It results in the changes of colour of the solution.

Here are the pictures of my group's result:
