Sodium Metal
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na⁺ cation.Symbol: NaSKU: n/a -
Chemicals
Sodium Nitrate
Sodium nitrate is the chemical compound with the formula NaNO₃. This alkali metal nitrate salt is also known as Chile saltpeter to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter. Sodium nitrate is a white solid very soluble in water.Formula: NaNO3SKU: n/a -
Chemicals
Sodium Nitroprusside
Sodium nitroprusside, sold under the brand name Nitropress among others, is a medication used to lower blood pressure. This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding.Formula: Na2[Fe(CN)5NO]SKU: n/a -
Chemicals
Sodium Oxalate
Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na₂C₂O₄. It is a white, crystalline, odorless solid, that decomposes above 290 °C. Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate solutions.Formula: Na2C2O4SKU: n/a -
Chemicals
Sodium Silicate
Sodium silicate is a generic name for chemical compounds with the formula Na ₂ₓSiO ₂₊ₓ or ₓ·SiO ₂, such as sodium metasilicate Na ₂SiO ₃, sodium orthosilicate Na ₄SiO ₄, and sodium pyrosilicate Na ₆Si ₂O ₇. The anions are often polymeric.Molecular Formula: Na2SiO3SKU: n/a -
Chemicals
Sodium Sulphate
Sodium sulfate is the inorganic compound with formula Na₂SO₄ as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.Formula: Na2SO4SKU: n/a -
Chemicals
Sodium Thiosulphate
Sodium thiosulphate is an inorganic compound with the formula Na₂S₂O₃xH₂O. Typically it is available as the white or colorless pentahydrate, Na₂S₂O₃·5H₂O. The solid is an efflorescent crystalline substance that dissolves well in water. It is also often called sodium hyposulphite or hypo.Formula: Na2S2O3SKU: n/a -
Chemicals
Starch Soluble
Due to the fact that starch (amylum) is a polysaccharide , a long chain compound consisting of glucose monomers it has poor solubility in most solvents. Some starches are water soluble because of the hydroxyl groups involved in the polysaccharide chain, some like the branched form amylopectin are more insoluble.

Stearic Acid
Stearic acid is a saturated fatty acid with an 18-carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid and its chemical formula is C₁₇H₃₅CO₂H. Its name comes from the Greek word στέαρ “stéar”, which means tallow. The salts and esters of stearic acid are called stearates.Formula: C18H36O2SKU: n/a -
Chemicals
Sulphur Powder
Sulphur is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S₈. Elemental sulfur is a bright yellow, crystalline solid at room temperature.Symbol: SSKU: n/a -
Chemicals
Sulphuric Acid
Sulphuric acid, also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H₂SO₄. It is a colorless, odorless, and syrupy liquid that is soluble in water and is synthesized in reactions that are highly exothermic.Formula: H2SO4SKU: n/a
