Dissociation theoryIn 1883, Svante Arrhenius was struck by the ideas for his dissociation theory during a sleepless night. This theory explains that substances like salt (ex. sodium chloride) when dissolved in water, dissociate (separate) into electrically charged ions (ex. positive sodium ions and negative chloride ions). The idea was controversial at first, but is now a basic fact in understanding the chemistry of ionic compounds. |
