Discussion Overview

The discussion revolves around the chemical equilibrium of the dissolution of silver chloride (AgCl) in water and the effects of adding sodium chloride (NaCl) to this system. Participants explore the implications of Le Chatelier's principle in this context, focusing on the changes in mass and concentration of the components involved in the equilibrium.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant describes the equilibrium of AgCl dissociating into Ag+ and Cl- ions and poses a question regarding the effects of adding NaCl to the system.
  • The participant speculates that adding NaCl would increase the mass of AgCl and decrease the concentrations of Ag+ and Cl- ions, but expresses uncertainty about the correctness of this reasoning.
  • Another participant identifies the situation as an application of Le Chatelier's principle, affirming the relevance of the initial question.

Areas of Agreement / Disagreement

Participants generally agree on the relevance of Le Chatelier's principle to the scenario, but there is uncertainty regarding the specific effects on mass and concentrations, indicating that the discussion remains unresolved.

Contextual Notes

Participants have not fully clarified the assumptions underlying their reasoning, and there is a lack of consensus on the specific outcomes of adding NaCl to the equilibrium system.

a question on equillibria

"Ionic compounds we normally designate as insoluble in water e.g. AgCl actually dissocitae to a small extent into constituent ions. these aqueous ions are in equillibrium with the solid as indicated in the following equation

AgCl(s) \Updownarrow Ag^{}_{}+ (aq) + Cl^{-} (aq)

if a beaker of water containg solid silver chloride, indicate if the equillibrium components increase, decrease or do not change when a solution of NaCl is added to the beaker

Mass of AgCl(s): \uparrow or\downarrow or constant

Concentration of Ag(aq): \uparrow or \downarrow or constant

Concentration of Cl(aq): \uparrow or \downarrow or constant


I have put mass of AgCl increase because adding more ionized Cl will interact with the Ag(aq)


and if this was true Ag(aq) and Cl(aq) would decrease, right?

But my biggest concern is does the Cl(aq) act with Ag(aq) to create a solid; I am just not sure if my logic is correct

any feedback would be greatly appreciated
 
Physics news on Phys.org
and i just read to not post questions here

So sorry
 
It is the application of the Le Chatelier's principle, and you are right.

Question will be moved by mentors sooner or later to appropriate forum.
