17. Give one difference between cation and anion and one example of each.
Answers
Answer:
Answer 1: Any one difference between cation and anion can be on the basis of electric charge. Furthermore, cation has either one positive charge or more than one positive charges. Moreover, anion has either one negative charge or more than one negative charges.
Answer:
The term ‘ion’ was 1st used by English physicist and chemist Michael Faraday in 1834 after a suggestion by English Polymath, Scientist, William Whewell. Michael Faraday used this term for those species which were moving one electrode to another through aqueous medium. The terms ‘anion’ and ‘cation’ are also coined by Faraday and Whewell. In 1884, Swedish scientist Svante Arrhenius explained that solid crystalline salts dissociate into paired charged particles when dissolved. For this he won the Nobel prize in Chemistry in 1903.
