Question

which are the ions present in HCl solution?

Answer 1

Answer:

● In Hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in Solution.

Answer 2

The ions present in HCl solution are hydronium ions $H_{3} O^{-}$and chlorine ions $Cl^{-}$.

• Hydrochloric acid (HCl) is considered to be a strong acid. As the acid is strong that means it will dissociate completely.  
• As it is an acid so, the ions present in the solution will include hydrogen ions H+ or hydronium ions $H_{3} O^{-}$
• Technically, the existence of hydrogen ions $H^{+}$, on their own is quite rare as these ions are not stable while reacting with water and thus form hydronium ions, $H_{3} O^{-}$.
• On the other hand, hydronium ions, $H_{3} O^{-}$. is quite stable as compared to hydrogen ions to exist in.).
• The negatively charged ions formed after the dissociation of hydrochloric acid is chlorine ions $Cl^{-}$.

Hence, the ions present in HCl solution are hydronium ions and chlorine ions.
