Hint: By knowing the chemical formulas of the salt we can say the chemical that contain chlorine atom. The salt which has chlorine atom is a salt of chlorine. Among these spirit of salt contains chlorine atom.
Complete Step by Step Answer:
Fischer salt is prepared by combining cobalt metal in $+2$ oxidation state and nitrite salts in the presence of oxygen gas. The sodium cobaltinitrite salt is more soluble in water. Thus it does not contain chlorine atoms.
Epsom is actually magnesium sulphate. It contains magnesium and sulphate groups thus it does not contain chlorine atoms.
Fremy’s salt is actually dipotassium nitrosodisulfonate. Thus it does not contain chlorine atoms.
When Hydrogen chloride or hydrochloric acid is dissolved in water the solution is also called the spirit of salt. It is a strong acid. It contains hydrogen and chlorine atoms. It is a polar covalent compound. Thus the spirit of salt contains chlorine atoms. Hydrogen chloride can easily donate its hydrogen atom and acts as a strong acid.
Thus the correct option is D.
Note: Spirit of salt is used in brick cleaning, metal cleaning. It is also used to adjust the pH of pool water due to strong acidic properties.
