(V) A solution of hydrogen chloride is an electrolyte but a solution of
tiny-mole [99]

Answer:

When hydrogen reacts with chlorine, hydrogen chloride is formed. Hydrogen chloride is a gas, and has the formula HCl(g).

When hydrogen chloride dissolves in water, hydrochloric acid is formed. This has the same formula, but you can tell the difference because of the state symbol (aq), which stands for ‘aqueous’. The formula is written as HCl(aq).

Hydrogen chloride is made from molecules. The hydrogen atom and the chlorine atom are joined by a covalent bond. When hydrogen chloride forms hydrochloric acid, the molecules split into ions.

HCl(aq) → H+(aq) + Cl-(aq)

The H+ ions make this aqueous solution acidic. The solution also conducts electricity because it contains ions that are free to move.

However, when hydrogen chloride gas dissolves in a solvent called methylbenzene, the molecules do not split up. A solution of HCl in methylbenzene does not contain hydrogen ions, so it is not acidic. The solution also has a low electrical conductivity.

According the recent research, ice skaters are able to glide smoothly across the ice because
erma4kov [3.2K]

Although ice is solid, as long as temperatures are above −20°C (−4°F) there is always a very thin layer of water on the surface that makes it slippery. Extra melted water from the rubbing between the blade and the ice vastly reduces the friction allowing the skater to glide across the ice with little effort.
