AI Thread Summary
When NaCl is added to a solution containing solid AgCl, the equilibrium shifts according to Le Chatelier's principle. The mass of AgCl remains constant, as the solid does not dissolve significantly in the presence of additional Cl^- ions. The concentration of Ag^+ ions decreases due to the common ion effect, while the concentration of Cl^- ions increases. This interaction can lead to the formation of more solid AgCl, confirming the initial concern about the reaction between Ag^+ and Cl^-. The discussion highlights the importance of understanding ionic equilibria in chemical reactions.

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.

thank you for the prompt reply
 
Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
