why is the ring of ammonium chloride closer to the hydrochloric acid end in the ring of gases experiment? i can say is that NH4Cl has greater amount of molecular weight than ammonium. is it right. pls help
No. NH3 is a gas and diffuses faster than HCl gas since NH3 has a lower molar mass than HCl.
In the "ring of gases" experiment, the position of gases in the ring depends on their solubility in water. Ammonium chloride (NH4Cl) is a salt that dissociates in water to form ammonium ions (NH4+) and chloride ions (Cl-). In this case, the position of the ring of ammonium chloride is closer to the hydrochloric acid (HCl) end because both ammonium and chloride ions have a similar behavior to HCl.
To determine why NH4Cl is closer to the HCl end, we need to consider the solubility of different ions. In this case, the chloride ion (Cl-) has a higher solubility in water compared to the ammonium ion (NH4+). This is because Cl- is relatively small and has a high charge density, allowing it to interact strongly with water molecules. Hence, it is more soluble and easily carried along with the water vapor towards the HCl end.
On the other hand, the ammonium ion (NH4+) is relatively larger and has a lower charge density compared to Cl-. It interacts less strongly with water molecules and, therefore, has lower solubility. As a result, it tends to remain closer to the source where it was formed (ammonium chloride).
To summarize, NH4Cl is closer to the HCl end in the ring of gases experiment because the chloride ion (Cl-) formed from NH4Cl has higher solubility in water compared to the ammonium ion (NH4+).
