Evaporates are found where there is water, such as soil. Three common evaporate minerals found in soil are Anhydrite, Mirabilite, and Thenardite.

Common Chinese patent drugs like the health&beauty InnerPure capsules are actually the laxative. Its active components are the rhubarb and mirabilite. The mirabilite is a kind of mineral, whose main component is the sodium sulfate. Once the capsule has been taken, the contained sodium sulfate starts to take a series of reactions The sodium sulfate is hydrolysis to produce a large amount of sulfuric acid root ions, which are easy to be absorbed by the intestinal mucosa. So these ions persist in the intestinal to form the hypertonic solution, causing intestinal moisture to be not absorbed. As a result, the intestinal volume increases to stimulate peristalsis, resulting in diarrhea.

Firstly i would like to add that sodium is an element and not a compound. sodium is never pure as pure sodium ignites at ambient temperatures but it is also the 7th most abundant element found mainly in the form of rocksalt(NaCl).it may also be found as salts like borax,trona,saltpetre,mirabilite,etc

Mixing sodium and sulfuric acid would result in a reaction that produces sodium sulfate, hydrogen gas, and heat. The reaction is highly exothermic and can be potentially dangerous if not handled properly.

Sodium Sulfate

Na has a charge of 1+ and Sulfate (SO4) has a charge of 3-

So, in order for them to bond, you need to have 3 Sodium atoms for every 1 Sulfate molecules.
