INTRODUCTION
One of the key objectives in the teaching of chemistry is the development and tuning experience to motivate, developmaterials that are readily available and whose cost is as low as possible. Involves the construction of an electrolytic cell using everyday materials. It studied reactions ofelectrolysis of a 1 M KOH solution, a solution of NaCl 5% w / v 5% solution of KI.

OBJECTIVE
• The objective of this work consists on the one hand, the constructionof an electrolytic cell with common materials and the development of some reactions of electrolysis in the same

MATERIALS
• 3 syringes of 10 ml.
• 1 power topreserve food disposable PET 14 cm in diameter and 6 cm tall with lid.
• 2 wires of nickel (electrolytic quality) of 3 cm long
• 2 cables (50 cm long c / u) at the endsmust be welded alligator connectors
• 1 9 V battery
• 1 tripod
• 8 cm PVC or rubber tubing of similar diameter to the end of the syringe.
• 2 blades
• press clipsto seal the electrode material (Fastix)

PROCEDURE
the solution is added which will host the electrolysis
and then u pull the plunger that displaces the air in thecompartment where an electrode, so the solution rises to completely fill the space. Immediately press the PVC hose with a clip.
Finally connect the electrodes at theends protruding from the bucket to the pile. At the start of electrolysis gas evolution was observed.
