Question

According to table f which ions combine with chlorine ions to form an insoluble compound 1- Fe2+ions.
2- Ca2+ions
3- Li+ions.
4-Ag+ions

Answer 1

Answer: Option (4) is the correct answer.

Explanation:

When silver ions $(Ag^{+})$ 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, $Ag^{+}$ and  $Cl^{-}$.

Hence, AgCl is insoluble in water.

Whereas $FeCl_{2}, CaCl_{2}, and LiCl$ are soluble in water.

Answer 2

The ions which combine with chlorine ions to form insoluble compound are the silver ions (Ag⁺). The correct option is 4- Ag+ions

Solubility

From the question,

We are to determine which ions combine with chlorine ions to form an insoluble compound.

All chloride salts are readily soluble in water, except Mercurous chloride and silver chloride. Lead chloride is only slightly soluble.

Among the given ions, the ion that will combine with chlorine ion to form an insoluble compound is silver ion (Ag⁺)

Hence, the ions which combine with chlorine ions to form insoluble compound are the silver ions (Ag⁺). The correct option is 4- Ag+ions
