You must eliminate this solution from électrode use a seringue,wach all of volume of electrode and add kCl saturés.just clean a potos paroie to instore contact
Neha Patel you can dip the electrode in a large amount of water replace the solution daily , all the KI will comeout in water . then fill sat KCl solution
You can take out the silver wire from the tube, polish the wire or remove the AgCl coating by immersion in amonia solution. Re-coat the silver wire with AgCl by making it as an anode in 0.1 M Hcl solution. Connect the electrode to a power supply. Use a smal current as can be indicated from the rate of hydrogen evolution. You will see in few minutes that the wire turns brown. Keep the wire to age in a 0.1 KCl + few drops of AgNO3 soltion. After that fill the reference electrode tube with 0.1 KCl solution and insert the wire in place .
