Match the following Column A Column B 1. Insulator a. Positively charged ions 2. Cathode b. Asbestos 3. Cations c. Electrode which attracts cations 4. Anode d. Decomposition of electrolyte by passage of electric current 5. Electrolysis e. Electrode at which attracts anions

1 . Insulator b. Asbestos 1 . Insulator - b. Asbestos Asbestos is an excellent electrical insulator and is highly resistant to heat and electricity. 2 . Cathode c. Electrode which attracts cations 2 . Cathode - Electrode which attracts cations The cathode is negatively charged electrode. The cathode attracts cations or positive charge. 3 . Cations a. Positively charged ions 3 . Cations - Positively charged ions Positively charged ions are called cations. It is attracted towards cathode. 4 . Anode e. Electrode at which attracts anions 4 . Anode - Electrode at which attracts anions The positively charged electrode in electrolysis is called the anode. Negatively charged ions are called anions. They move towards the anode. 5 . Electrolysis - d. Decomposition of electrolyte by passage of electric current Electrolysis is the process of decomposition of an electrolyte into constituent ions by the passage of electric current through it.
