I'm not sure it has one. It can't really "decay"; as far as I know, it should last essentially forever.
Yes it slowly oxidises to Ferric Sulfate
i think 6 month becoz the ferrous ion stability is also 6 month navin
The minerals beneficial to the human body are: sodium potassium chloride calcium phosphate sulfate magnesium iron copper zinc manganese iodine selenium molybdenum

Indefinite, if the containers were tightly sealed.
At least 1year at roomtempandaway from sunlight.

A liquid solution in a closed container has a shelf life of about 4 months. The crystaline form in a closed container has a very long shelf life.
18 months
Pure codeine base is not very soluble in water, and has a short shelf life. When codeine base is mixed with a dilute strong acid, such as Sulfuric Acid, it forms a salt: Codeine sulfate. This salted version is more water soluble and has a longer shelf life. Most medicines are salted in this manner.
Copper sulfate will interact with and corrode aluminum. If this aluminum is a pontoon on a boat, the corrosion will puncture holes in the pontoons, so make sure that everyone onboard has a life preserver.
12 month
2 weeks
Practically forever. If it dries out, it can be put back in solution by just adding alcohol.
You should take the solution to the Pharmacy or supplier you received it from and they can tell you. Any prescription or medication you receive from the Pharmacy or your doctor has a different "shelf life" expectancy and if you ask for the expiration date, they will add that information to the prescription label.
Ammonia solution is not very stable; the gas NH3 is released in time.
