SUMMARY

The discussion centers on the effect of adding silver nitrate to the equilibrium reaction CoCl4 2- + 6H2O ⇌ Co(H2O)6 2+ + 4Cl- + energy. It is established that adding silver nitrate, which dissociates into Ag+ ions in solution, does affect the equilibrium by introducing a new ion into the system. The participants clarify that adding solids does not impact the equilibrium position, while the addition of gases or aqueous solutions can influence the equilibrium depending on their presence in the equilibrium expression.

Homework Statement


CoCl4 2-+6H2O --> Co(H2O)62++4Cl-+energy
If I add silver nitrate, which direction does it shift?
I think it is no effect, because adding solid does not affect the equilibrium?... Am i right?

Btw, what happen if i add aqueous to X gas --> Z gas + Y gas, vise verse...
or gas to x(aq)--->Z aq + Y aq
Thanks

Silver nitrate is not being added as a solid. Assume that it is being added as a dissociated species in solution. What effect would the Ag+ ion have on the equilibrium?

I can't tell what you are asking about your gases but I assume that you are adding water vapor to a mixture of interconverting gases at equilibrium, yes? If the partial pressure of water vapor doesn't appear in the equilibrium expression, will it change the equilibrium?
