Hey everyone, We're asked based on the shot ladies principle, what will happen to the soluble itty of silver cyanide when potassium chloride is added to the solution first? Let's go ahead and write out our reactions here. So we have silver cyanide which is in its solid state. This will dissociate into our silver ion plus our cyanide ion. Now let's go ahead and take a look at our potassium chloride. Now potassium chloride is going to dissociate into our potassium ion plus our chlorine ion. Looking at these two reactions, we can see that there is no common ion and because there is no common ion, this means that there will be no change in the acidity of the solution. So our answer here is going to be that the solid ability of silver cyanide will remain the same. Now I hope this made sense. And let us know if you have any questions.
