Potassium Sulfide

            Potassium Sulfide is an inorganic chemical compound of Potassium and Sulfur; it is colorless solid and has rotten egg smell. It is difficult to find as solid because it is very active and reacts with water easily and forms potassium hydro-oxide and potassium bi-sulfide. It is highly flammable and produces irritating toxic gases after explosion. It may explode when comes in contact with air, acid, and water. Direct contact may cause skin and eye burning.

            Sulfur atom has valency 2 (negatively charged) while potassium atom has valency 1 (positively charged); one atom of sulfur combines with two atoms of potassium to form one neutral molecule of potassium sulfide. Potassium and Sulfur atom representation are: K⁺ and S^-2. Other compounds of sulfur are: K₂SO₄ (K⁺, SO₄^-2); SO4 has valency 2 and negatively charged.

            Potassium sulfide is made by combining potassium solution in anhydrous ammonia and sulfur element; 2 K + S = K₂S. It is made by combining K₂SO₄ with coal at elevated temperature; K₂SO₄  + 4C  = K₂S  + 4CO; K₂SO₄  + 2C  = K₂S  + 2CO₂; C  (carbon) represents coal; CO is carbon monoxide gas and CO₂ means carbon dioxide gas.

Having dental problems lately? Have you noticed frequent bleeding of your gums? Or how about the sudden yellowish discoloration of your teeth? Or have you experienced people turning off on you because of your odious breath?

Well you do not need to go to the dentist and spend some serious cash on check-ups and medications. All you need is a good tube of potassium sulfide. Yes, you heard that right, potassium sulfide.

Now I know you are thinking that this might be another hoax, but it is actually not. Unlike other commercially advertised chemicals for teeth problems that are massive on promises but poor on performance, potassium sulfide is truly a dental wonder.

So what makes this chemical a good accompaniment and solution for your dental concerns and problems? Let us find that out and more on the article below.

Potassium sulfide is a naturally occurring chemical in the Earth's stratosphere, but is also found as a tangent object in rocks and certain land formations. It was first used as a gluing component in building houses and buildings.

It was in late 1870's that it was discovered that the chemical is able to address dental problems when a German dentist, Carl Wild, used it to address the then considered incurable gingivitis of his patient.

But this did not go out with a lot of problems. There were a lot of doubts and misconceptions following the use of this chemical. The type of potassium chloride being extracted from rocks and land formations are the natural form.

It was found out later on, that the unprocessed chemical has radioactive components that are able to cause life threatening cancers and dangerous radiation-related conditions. It was banned during the 1890 and was never seen in the medical field ever since then.

But thankfully, a scientist that goes by the name of Dr. Patnubay Buan, was able to restudy and research the facts and the information and medical records that the country has about the use of this very controversial chemical.

According to Patnubay's study, potassium sulfide is not that harmful when it is reconstituted into its natural and chelated form. In fact, when it is in this natural form it is very advantageous to the anatomic structures found in the oral mucosa.

Structures like the teeth and the gums generally benefit a lot from the use of this chemical. It strengthens the teeth and it help solidify the tissue networks of the gums so that perennial and persistent bleeding will stop.
