Aqueous solution of gaseous HCl is acidic but solution of HCl gas in benzene has no acidic property?

This is because of the polarity of the solvents. Aqueous solution (H2O) is very polar and will produce H+ ions when HCL is added, thus resulting in a acidic solution. On the other hand, benzene, a nonpolar solvent will not produce H+ ions and no acidic properties.

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.

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 is the standard enthalpy change for the reaction that represents breaking all the bonds in gaseous benzene?
The standard enthalpy change for breaking all the bonds in gaseous benzene is the bond dissociation energy, which is the total energy required to break all the bonds of benzene. This value is approximately 1670 kJ/mol.
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.
Why is HCl predominantly covalent in gaseous state but is ionic in aqueous solution?
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.
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.

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.
What is solubiuty?
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent.
Is steel a gaseous solution?
No. Steel is a solid solution. An example of a gaseous solution would be air.

What are the gaseous pollutants present in cigarette smoke?
off the top of my head, nocotine, tar, benzene, CO.
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.
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.
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.
