According to table f which ions combine with chlorine ions to form an insoluble compound 1- Fe2+ions.
2 answers:
Answer: Option (4) is the correct answer.
Explanation:
When silver ions combine with chlorine ions then it results in the formation of silver chloride (AgCl).
The forces holding silver and chlorine atoms together are strong enough to be overcome by the formation of hydrated ions, that is, and
.
Hence, AgCl is insoluble in water.
Whereas are soluble in water.

Answer and Explanation:
DIFFERENCE BETWEEN ELEMENT AND COMPOUND :
- An element is made up of same type of atoms whereas a compound is made up of different type of atoms.
- A compound can be separated by chemical methods but an element can not be separated by chemical methods.
- Example of element is Cu Fe C and example of compound is
etc
- Elements can not be split into different substances but compound can be splited into different substances
