“HOMEMADE INK” Abstract: Ink is a colored liquid or paste-like substance used for writing, printing, or drawing on various surfaces. It is very helpful for us students especially in making our reports and presenting it through visual aids. The commercial ink is a bit expensive that is why an experiment like a homemade ink was of great help. We just need Iron sulfate compound and Tannic acid to make it. Even though the result of our homemade ink is not as satisfactory as the commercial ink, but nevertheless it helps us in writing. INTRODUCTION: Ink, any liquid or viscous pigmented substance used for writing, printing, or drawing. The composition and consistency of an ink vary according to the purpose for which it is used.

Iron sulfate and tannic acid are the materials needed to make ink. REVIEW OF RELATED LITERATURE: Characteristics of Iron sulfate: Iron forms ferrous compounds in which it has a valence of +2 and ferric compounds in which it has a valence of +3. Ferrous compounds are easily oxidized to ferric compounds. The most important ferrous compound is ferrous sulfate (FeSO4), called green vitriol or copperas; it usually occurs as pale-green crystals containing seven molecules of water of hydration. It is obtained in large quantities as a by-product in pickling iron and is used as a mordant in dyeing, as a tonic medicine, and in the manufacture of ink and
