Re: Agree, or disagree ?

The monopositive silver cation is colorless in aqueous solution. divalent silver is not stable in water, and is not a consideration. If a solution contains only silver ion, it is 100% colorless. the silver ion is easily reduced to metal by the action of uv light, which is why if one exposes a solution of silver ion to light, it becomes darker as any chemist knows, and is always why solutions such as silver nitrate are stored in amber bottles.

If one suspects the presence of silver ion in a solution , a simple test is to add a small amount of a dilute solution of table salt . Upon mixing, the chloride in the salt forms a milky white precipitate with any silver ion present, silver chloride.
