I have 30g of silver nitrate in crystal form from which I'm planning on making a 12% solution.
Ideally, I would use all 30g at once and have 250ml of solution. This is because even though making the solution is rather easy, I'd prefer to only have to do it once for this amount of AgNO3.
My questions are: Is there an advantage in terms of longevity for crystals over a solution? AND, What would be the most proper way to store the solution? Stoppered brown glass bottle?
