Question

Which compound becomes less soluble in water as the temperature of the solution is increased

Answer 1

The answer is HCl.

Step-by-step explanation:

Looking at Table G on the reference table, you can see as temperature increases, the solubility line for HCl goes down.

Answer 2

HCl

Step-by-step explanation:

HCl is less soluble in water with increasing temperature of the solution because it is a polar covalent compound. With increasing temperature it is easier to break the covalent bonds, allowing the electrons to be free and to dissolve more easily in water.
