Copper sulphate (also spelled copper sulfate) is a blue crystalline chemical compound with the formula CuSO₄. It usually appears as copper(II) sulphate pentahydrate (CuSO₄·5H₂O), which is the common bright blue solid you may have seen in labs.

• Chemical Formula: CuSO₄ (anhydrous), CuSO₄·5H₂O (pentahydrate)

• Appearance: Blue crystals (pentahydrate), white powder (anhydrous)

• Molar Mass: 159.61 g/mol (anhydrous), 249.68 g/mol (pentahydrate)

• Solubility: Soluble in water, producing a blue solution

• Nature: Toxic, irritant, acidic in solution

• Agriculture: Fungicide, herbicide, pesticide (Bordeaux mixture in vineyards)

• Chemistry labs: For crystallization experiments, Fehling’s solution, Benedict’s solution

• Industry: Electroplating, textile dyeing, leather treatment

• Public health: Used to kill algae and parasites in water tanks/pools (in controlled amounts)

• Toxic if ingested

• Can cause skin/eye irritation

• Must be handled with gloves and protective eyewear

Dextrose anhydrous is a simple sugar — a form of glucose — that contains no water molecules (anhydrous = "without water"). It is the anhydrous (dry) form of D-glucose, a naturally occurring sugar important in biology and energy metabolism.

• Dextrose is just D-glucose (the naturally occurring isomer).

• "Anhydrous" means it has been fully dried — no water of crystallization.

• Other common forms:

  • Dextrose monohydrate: Contains one water molecule per glucose molecule.

  • Dextrose anhydrous: Pure glucose, fully dried.

• Generally recognized as safe (GRAS) when used appropriately.

• Can cause hyperglycemia if administered in excess intravenously.

• Store in a cool, dry place to prevent clumping or degradation.

Refined Glycerine (also called Glycerol or Glycerin) is a colorless, odorless, sweet-tasting, viscous liquid widely used in pharmaceuticals, cosmetics, food, and industrial applications.
