SUMMARY

Hydrochloric acid (HCl) is primarily a covalent compound, but it exhibits ionic properties when dissolved in water, acting as a strong electrolyte. The electronegativity difference between hydrogen and chlorine leads to a polar covalent bond, resulting in the dissociation of HCl into H+ and Cl- ions in aqueous solution. This ionic behavior is due to the stability of these ions in water, which is supported by the ordered arrangement of water molecules around them. Therefore, while HCl is covalent in its molecular form, it demonstrates ionic characteristics in solution.

PREREQUISITES
  • Understanding of covalent and ionic bonding
  • Knowledge of electronegativity and its effects on molecular structure
  • Familiarity with strong electrolytes and their behavior in solution
  • Basic concepts of molecular interactions in aqueous environments
NEXT STEPS
  • Research the concept of electronegativity and its role in bond polarity
  • Study the properties and behavior of strong electrolytes in water
  • Examine the molecular structure of HCl and its dissociation in aqueous solutions
  • Explore the arrangement of water molecules around ions in solution
USEFUL FOR

Chemistry students, educators, and professionals interested in understanding the properties of acids and their behavior in aqueous solutions.

Hey
Can someone explain to me how pure hcl is covalent, and what happens when it is dissolved in water? I know it conducts electricity. But I am a bit lost

Is it really covalent? Consider the electronegativites.

For the second part, you should be able to locate a picture in your text, which shows the ordered arrangement of water molecules around the H+ and Cl-, HCl is a strong electrolyte in water at room temperature.
 
There is nothing called a pure Covalent..compound.

Nothing is purely covalent.
Only the molecules are.

Think of HCl as:--
H-Cl, with Cl having the bonding electron cloud closer to it.
In water, the picture is that due to fact that
H^+ + Cl^- is of low energy, so it is stable in the solution, rather than the undivided molecules.
