Electrolytic dissociation and ionization
उत्तर
Electrolytic dissociation and ionization :
| Sr.No. | Ionization | Electrolytic dissociation |
| 1. | Formation of positively or negatively charged ions from molecules which are not intially in the ionic state. | Separation of ions which are already present in an ionic cmpound. |
| 2. | Polar covalent compounds show ionization. | Electrovalent compounds show dissociation. |
| 3. | For example : HCl | For example : KCl |

Three different electrolytic cells, A, B and C are connected in separate circuits. Electrolytic cell A contains a sodium chloride solution. When the circuit is completed, a bulb in the circuit glows brightly. Electrolytic cell B contains an acetic acid solution and in this case, the bulb in the circuit glows dimly. The electrolytic cell C contains a sugar solution and the bulb does not glow. Give a reason for each of these observations.
