Hey everyone, we're asked based on the shot Leslie's principal, what will happen to the solid ability of silver cyanide when silver per chlorate is added to the solution first. Let's go ahead and write out our reactions here. So we have our silver cyanide in its solid state and this will dissociate into our silver ions, plus our cyanide ion. Now let's go ahead and look at silver per chlorate. Looking at silver per chlorate, we can see that this associates into our silver ions as well, plus our per chlorine ions. Looking at these two reactions, we can see that we have a common ion which is going to be our silver ion. Now because of this common ion, this means that the concentration of our silver ion will increase and because this increases, our equilibrium will shift in the reverse direction. So in this case to the left. So based on the shot, Leslie's principle, the soluble itty of our silver cyanide will decrease. Now, I hope this made sense. And let us know if you have any questions
