It is the mineral calcium sulfate with two water molecules attached. By weight it is 79% calcium sulfate and 21% water. Gypsum has 23% calcium and 18% sulfur and its solubility is 150 times that of limestone, hence it is a natural source of plant nutrients. Gypsum naturally occurs in sedimentary deposits from ancient sea beds.

It's water soluable but takes some stirring to get it into solution. I won't expect it to lower the pH of the water. It will lower pH of the soil as the ammonium is absorbed by the plant or converted to nitrate.
