The two standard methods of drying a powder are putting in an oven, and mixing with silica gel. You can reuse silica gel by heating it in an oven to dry it.

I am trying to make a highly concentrated silver citrate solution but encountered a problem. The first time I did this I did not have this issue. I took silver oxide powder and put it in distilled water. Then I added citric acid until it could all dissolve, stirring vigorously. Made about 1,000PPM

This time I first made a solution nearly saturated with citric acid. Then I added the silver oxide. But it appears the silver oxide is a little clumpy and does not disperse into a fine mist will stirring it. I think it may be because of some moisture in the jar of silver oxide powder I have. The result is that the silver oxide is taking forever and ever to dissolve and is very frustrating. It is dissolving, but just super slowly. Almost up to 5,000PPM. I won't be able to tell when saturation with silver really happens if the reason for not dissolving is due to something else.

Any ideas how to remove the moisture? Adding grains of rice to the silver oxide bottle?

A tiny swig of the 1,000PPM had an effect on me, so I need to explore higher concentrations (while staying out of the sun).
