HCl is a polar covalent compound. When it is dissolved in Polar solvent H2O, it is ionized into its constituent ions H+ & Cl-. But when it is present gaseous form then it remains as Covalent compound HCl.

In the gaseous state, HCl exists as discrete HCl molecules due to the strong electrostatic attraction between the hydrogen and chlorine atoms, making it predominantly covalent. In aqueous solution, HCl molecules dissociate into H+ and Cl- ions due to interaction with water molecules, resulting in an ionic bonding behavior.

Is pH value only for liquids?
No, pH value can also be measured in gaseous and solid substances. In solids, the pH value is defined as the pH of a saturated solution of the solid in water. In gaseous substances, pH value is measured by dissolving the gas in water.
Aqueous solution of gaseous HCl is acidic but solution of HCl gas in benzene has no acidic property?
In an aqueous solution of gaseous HCl, the HCl molecules dissociate into H+ and Cl- ions, which react with water to form H3O+ ions, resulting in an acidic solution. In benzene, which is a nonpolar solvent, the HCl molecules do not dissociate into ions due to the absence of water molecules to facilitate the ionization process, so the solution does not exhibit acidic properties.
What does the state symbol aq mean when written after a chemical compound in a chemical reaction?
The state symbol "aq" indicates that the substance is dissolved in water, meaning it is in aqueous solution. This is important information in chemical reactions as the state of a substance can affect its reactivity and behavior.
What is gaseous solution?
A gaseous solution is a homogeneous mixture of gases, where one or more gases are dissolved in another gas. The composition of gaseous solutions is typically expressed in terms of partial pressures. Examples include air, which is a gaseous solution of nitrogen, oxygen, carbon dioxide, and other gases.
Is sterling silver a gaseous solution?
No, sterling silver is not a gaseous solution. It is a solid solution made of 92.5% silver and 7.5% other metals, usually copper. Gaseous solutions are mixtures of gases where the components are uniformly distributed at a molecular level.
Is pH value only for liquids?
No, pH value can also be measured in gaseous and solid substances. In solids, the pH value is defined as the pH of a saturated solution of the solid in water. In gaseous substances, pH value is measured by dissolving the gas in water.
What are the types of solutions?
The types of solution are liquid(aqeous), solid, and gaseous.

Is steel a gaseous solution?
No. Steel is a solid solution. An example of a gaseous solution would be air.

A solution is a type of?
Gaseous Solution, includes gases or vapors dissolved in one another. Two or more gases can form a solution. Air is an example of a gaseous solution.

What is the significance of symbol aq in a compound?
The symbol "aq" indicates that a substance is dissolved in water, meaning it is in an aqueous solution. This notation is commonly used in chemistry to distinguish substances in solution from solid or gaseous forms.
What does aq s g and l mean in chemistry?
These are called "state symbols". In chemical equations, they tell us what form the compounds/elements etc. are present in: * (s) tells us that the substance is solid, such as 'CaCO3(s)' * (l) tells us that the substance is liquid or molten, such as 'H2O(l)' * (g) tells us that the substance is gaseous, such as 'CO2(g)' * (aq) tells us that the substance is in solution ie. aquaeous, such as 'HCl(aq)'
