Why HCl is covalent in gaseous state but ionic in aqueous state?

In HCl, the electronegativity difference in Cl and H atoms (3.0-2.1) is 0.9. Therefore, it is predominantly covalent in the gaseous state. When dissoved in water which is of polar nature, there an attraction between the atoms of the acid and polar H2O molecules. This helps in the ionisation of the acid.

Does HCl conduct electricity aqueous solution?

Ionic solutions have the capability to conduct electricity. Therefore, hydrochloric acid (HCl in solution of water) can conduct electricity because it forms ions. Unless you put hydrogen chloride (pure HCl) in water, it will not conduct electricity.

Why do some compounds conduct electricity in aqueous solutions?

Conduction of electricity Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Why do covalent compounds conduct electricity?

A covalent bond is formed between non metal atoms, which combine together by sharing electrons. Covalent compounds have no free electrons and no ions so they don’t conduct electricity.

Why do covalent molecules conduct electricity?

Covalent molecular structures do not conduct electricity because the molecules are neutral and there are no charged particles (no ions or electrons) to move and carry charge.

Why HCl is a covalent compound?

HCl is a covalent compound not an ionic compound because , it is formed by sharing of one electron each by Hydrogen and Chlorine, thus forming a single covalent bond.

Why is HCl a good conductor of electricity?

Hydrochloric acid is a strong electrolyte and dissociates completely in aqueous solution. The solution contains free mobile ions which allow electric current to pass through it. Hence, hydrochloric acid is a good conductor of electricity.

Which compounds conduct electricity are they ionic or covalent?

Although solid ionic compounds do not conduct electricity because there are no free mobile ions or electrons, ionic compounds dissolved in water make an electrically conductive solution. In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

What is the main reason why covalent compound do not conduct electricity?

Covalent molecular structures do not conduct electricity because the molecules are neutral and there are no charged particles (no ions or electrons) to move and carry charge. insoluble in water. Most covalent compounds are insoluble in water.

Why is HCl gas a covalent compound but aqueous solution conducts electricity?

Originally Answered: HCL gas is a covalent compound but its aqueous solution conducts electricity. Why? For explaining this question Faizan’s law is quite enough,it says that no bond is 100 percent covalent and 100 percent ionic means covalent bond also have some percent of ionic character and ionic bond have some percent of covalent character.

Is HCl a covalent or ionic compound?

HCl gas is a covalent compound but in the aqueous solution, it ionizes to form hydrogen ions and chloride ions. In the aqueous solution, hydrogen ions react with a water molecule to form hydronium ions. Was this answer helpful?

Can KCl conduct electricity in its aqueous state?

KCl is an ionic compound while HCl is covalent but both conduct electricity in their aqueous state. Why? Does this imply that polar covalent compounds can conduct electricity when dissolved in water? – Quora KCl is an ionic compound while HCl is covalent but both conduct electricity in their aqueous state. Why?

What is the action of HCL on aqueous solution?

(iii) It gives both hydrogen and hydroxyl ion in the solution. (iv) It forms hydronium ion in the solution due to the combination of hydrogen ion with water molecule. HCl gas is a covalent compound but in the aqueous solution, it ionizes to form hydrogen ions and chloride ions.
