Why does hydrogen chloride not react with methylbenzene?
The Cl will be attracted to the slightly positive H in water and the H will be attracted to the slightly negative O in water. The HCl molecule will dissociate as a result because of these strong attractions. With methylbenzene, no such attraction exists, thus HCl will not dissociate.
Why is a solution of hydrogen chloride gas in methylbenzene is not acidic to litmus?
The H + ions make this aqueous solution acidic . 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.
Why does hydrogen chloride gas has no effect on dry litmus paper?
Answer: It does not dissociate into H+ ions when dry HCL is used. Only in aqueous solution can acids dissociate into ions. Since HCL is not aqueous and the litmus paper is not wet in this case, the colour of the litmus paper does not change.
Why hydrogen chloride HCl does not conduct electricity but a solution of hydrogen chloride and water does conduct electricity?
HCI gas does not conduct electricity, but hydrochloric acid conducts electricity because in hydrochloric acid( aq), hydrogen ions are present to facilitate the movement of electrons whereas no such medium is present in gas.
What two things must happen before hydrogen and chlorine can react?
They dissolve in water to produce acidic solutions . Hydrogen chloride dissolves in water to produce hydrochloric acid, HCl(aq)….Reactions with hydrogen.
| Halogen | Reaction |
|---|---|
| Chlorine | Explodes with a flame or in sunlight, forming hydrogen chloride |
What happens when ammonia is dissolved in methylbenzene?
This is mainly because solution of ammonia in methylbenzene is basic since it is dry thus no effect on a litmus paper while, when in water is usually acidic thus turns a red litmus paper blue. Ammonia solution has ammonium hydroxide and water and the ammonium hydroxide is basic in benzene rings.
Why is hydrogen chloride a gas at room temp?
Hydrogen chloride molecules have weak intermolecular forces, which are easily overcome by the motion of the molecules at room temperature.
Why an empty flask is used in preparation of HCl?
(c) The empty flask acts as Anti-Suction device. In case the back suction occurs the water will collect in it and will not reach the generating flask. Prevents or minimizes back suction of water. Provides a large surface area for absorption of HCl gas.
Why dry hydrogen chloride gas does not turn blue litmus red whereas dilute hydrochloric acid does?
Dry hydrogen chloride gas does not turn blue litmus to red whereas hydrochloric acid does. Dry hydrogen chloride does not give hydrogen ions so it does not act as an acid, as a result does not turn blue litmus red. On the contrary, hydrogen chloride acid in water gives H+ ions and turns blue litmus red.
Why dry HCl gas does not turn dry blue litmus red but it turns moist blue litmus red?
Dry hydrogen chloride gas does not turn blue litmus red when hydrochloric acid does. Dry hydrogen chloride does not give hydrogen ions and so it does not act as an acid and does not turn blue litmus red. On the other hand, hydrogen chloride acid in water gives H+ ions and turn blue litmus red.
Why does hydrogen chloride gas not conduct electricity but hydrochloric acid can?
In the gas phase HCl is not “ionic.” The bonds in HCl(g) have high covalent character. When HCl gas is dissolved in water (forming hydrochloric acid) it separates completely (it is a strong acid) into H+ ions and Cl- ions and such a solution will readily conduct electricity.
Why HCl conducts electricity as a solution even though it is a molecular gas at room temperature?
For example, hydrogen chloride gas (HCl) is a simple covalent molecule, but it reacts with water to form hydrochloric acid. The solution of the acid contains H + ions and Cl – ions, so it will conduct electricity.
Why does the litmus turn red in methylbenzene?
Thus, the litmus turns red. Methylbenzene, on the other hand, is incapable of associating with hydrogen from the hydrogen chloride to produce a free proton. Bear in mind that H+ does not exist, although, for convenience, the solvated proton is often written as H+.
What happens when HCl reacts with litmus paper?
What affects litmus paper is hydrogen ions, H+ (aq). Hydrogen chloride reacts with water to form these: HCl molecules become H+ (aq) and Cl- (aq). Hydrogen ions do not form without a molecule such as water with a lone pair to carry them.
Why does HCl in methylbenzene conduct electricity?
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.
What happens when hydrogen chloride gas dissolves in methylbenzene?
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.
