How can you decrease solubility of poorly soluble salt?


What needs to be added in the solute? Why?

The decrease in the solubility of a salt occurs when a salt is dissolved in
a solution that already contains another source of the same ions.

For example adding AgCl to Nacl, the solubility of AgCl decreases.



Would this be an ok answer? Anything else I need to take in consideration?

So basically adding another substance ( with the same ions ) will decrease the solubility of the other? Was this right? Sorry, English is not my first language...

If you already have an insoluble salt, why do you need to decrease its solubility?

It's a speculative question. Doesn't necessary have to be insoluble, it can be "poorly" soluble.
