For investigatory projects in chemistry, you can chose from the following options

1) Comparative study of commercial antacids

2) Compare the caffeine content of different samples of tea

3) Analysis of some fruit and vegetable juices for the contents present in them

4) determination of the percentage of fatty material present in different soap samples

5) Study of displacement reactions : In this topic, you can investigate the displacement of less reactive metal by more reactive metal, with the help of electrochemical series. You can also broaden the scope of this project, by including some double displacement reactions.

6) Chelate formation by d-block elements: In this project, you study the conditions for formation of chelate formation by Nickel with Dimethylglyoxime (DMG).
