Answer :
HCI are less soluble in water as the temperature of the solution is increased.
Answer: Option (1) is the correct answer.
Explanation:
Compounds in which atoms transfer electrons result in the formation of ionic bond. Whereas when atoms in a compound share electrons then they result in the formation of covalent compounds.
Also, it is known that like dissolves like. Hence, water being an ionic compound itself dissolves other ionic compounds.
Thus, out of the given options HCl is a covalent compound, therefore, HCl is the compound that becomes less soluble in water as the temperature of the solution is increased.
