Potassium nitrate Full-time Job

Potassium nitrate ;is a chemical compound. It is an ionic salt of potassium ions K+ and nitrate ions NO3?, and is, therefore, an alkali metal nitrate. It occurs in nature as a mineral, niter (or niter in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or saltpeter in North America).

Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants, and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Potassium nitrate has an orthorhombic crystal structure at room temperature, which transforms into a trigonal system at 129 °C (264 °F).

Nitrates are a set of compounds that involve nitrogen and oxygen molecules. While they are often associated with cured meats, green, leafy vegetables are actually much richer in nitrates.

While the association of nitrate with cured meats causes some to worry about their cancer-causing effects, other studies show that the nitrates found in vegetables may actually help reduce the risk of cancer. Studies suggest that eating foods rich in natural nitrates can help reduce your risk of a number of chronic health conditions, whereas eating foods high in added nitrates can cause health risks.

What is Barium Chloride?

Barium Chloride ;is the inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. It is also hygroscopic.

How is it used?

Barium Chloride Dihydrate is used in wastewater treatment, the production of PVC stabilizers, oil lubricants, barium chromate, and barium fluoride. As an inexpensive, soluble salt of barium, Barium Chloride finds wide application in the laboratory. It is commonly used as a test for sulfate ions. In industry, Barium Chloride is mainly used in the purification of brine solution in caustic chlorine plants and also in the manufacture of heat treatment salts, case hardening of steel, the manufacture of pigments, and the manufacture of other barium salts. Barium Chloride is also used in fireworks to give a bright green color. However, its toxicity limits its applicability.

Barium Hydroxide - Ba(OH)2

What is Barium Hydroxide?

Barium hydroxide ;is also called baryta with the formula Ba(OH)2. It is a clear white powder with no odor. It is poisonous in nature. It is ionic in nature, for example, Ba(OH)2 (barium hydroxide) in an aqueous solution can provide two hydroxide ions per molecule. Barium hydroxide is the only reagent described for metalizing carboxamidesBarium hydroxide was less degradative as compared to barium oxide.

Ammonium sulfate ;is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.

The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.

It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.

As a food additive, ammonium sulfate is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration, and in the European Union, it is designated by the E number E517. It is used as an acidity regulator in flours and bread.

A basic guide to water soluble fertilizers.

Water soluble fertilizers ;are fertilizers that can be dissolved in water and added or leached out of the soil easily. With water soluble fertilizers it is easy to control the precise amount of nutrients available to your plants(the control is more exact with soilless mixes).Potassium carbonate ;is the inorganic compound with the formula K2CO3. It is a white salt, which is soluble in water. It is deliquescent, often appearing as a damp or wet solid. Potassium carbonate is mainly used in the production of soap and glass.

It is not suitable for acidic compounds but can be useful for drying an organic phase if one has a small amount of acidic impurity. It may also be used to dry some ketones, alcohols, and amines prior to distillation.
