ABSTRACT
Bleaching is the process in which net oral colouring matter is removed from a fiber, yana or fabries. It ranges from simple to complex type depending on the ingredeient moderal the bleach solution chosen in this research work is oxochtorale: (i) acid solution (Hocl). The bleach was produced when 100mls of hydrochloric acid was pound into the flask and 20g of potassium tetraozo magnate (vii) was also put into the round bottom flask. The flask containing the Hcl was connected into one of the opening, so that the Hcl ran into the round flask to make contact with the potassium tetraoxomaganate (vii) Kmno4. The chlorine gas was liberated and passed on till the water became saturated form exochlorate (i) acid, which is the bleach solution. This is an oxidative process. The equation is thus:
ch(g)+ H2O (L) Hoclca2)+ Hcl(og).
The oxochlorate (i) acid formed is an effective bleaching agent. The bleach produced was compared with commercially produced bleach. The control bleach used was Jik a product of PZ Nigeria plc. The result sowed that there was significant difference between the laboratory produced bleach and the commercially produced bleach solution.
