Paper Chromatography: Is Black Ink Really Black?

Science Fair Project Idea

Scientific Method

Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography. What do you think you will see if you use paper chromatography to look at the components of black ink? Is black ink just black? Find out for yourself! Read more
