What is the chemical name of the compound commonly known as 'Blue Vitriol'?
Copper Sulphate
Ferrous Sulphate
Magnesium Sulphate
Zinc Sulphate
Copper Sulphate
Blue Vitriol is the common name for Copper(II) sulphate pentahydrate. It is a bright blue crystalline solid that is highly soluble in water.
Blue Vitriol is the common name for Copper(II) sulphate pentahydrate. It is a bright blue crystalline solid that is highly soluble in water.
Think of it like a rechargeable battery; when the 'water' is locked inside the crystal structure, it is 'charged' with its signature blue color, but when 'drained' by heat, it loses its color and turns white.
BLUE = C-U (See You) - Copper (Cu) is associated with blue color.
CuSO4тАЛтЛЕ5H2тАЛO тАФ Chemical formula of Blue Vitriol (Copper Sulphate Pentahydrate)
CuSO4тАЛ тАФ Chemical formula of anhydrous Copper(II) sulphate
The chemical compound Copper(II) sulphate exists in various hydration states. The pentahydrate form, denoted as CuSO4тАЛтЛЕ5H2тАЛO, contains water molecules coordinated within its crystal lattice, which gives it its characteristic blue color. Upon heating, it loses this water of crystallization and turns into anhydrous copper(II) sulphate, which is white.
Blue vitriol belongs to the class of chemical compounds known as vitriols, characterized by their glassy, crystalline appearance.
It is a versatile compound used extensively in agriculture as a fungicide and in laboratories as an electrolyte.
It is toxic if ingested and acts as a strong irritant to the skin and eyes.
Effective algicide for water reservoirs
Essential reagent in chemical testing (e.g., Benedict's solution)
High toxicity to aquatic life
Corrosive to certain metals
Fungicide and herbicide in agriculture
Mordant in textile dyeing and pigment production
Ferrous sulphate (FeSO4тАЛтЛЕ7H2тАЛO) is known as Green Vitriol.
Zinc sulphate (ZnSO4тАЛтЛЕ7H2тАЛO) is known as White Vitriol.
Magnesium sulphate (MgSO4тАЛтЛЕ7H2тАЛO) is commonly known as Epsom salt.
A is correct тАФ Blue Vitriol is the common name for the pentahydrate form of Copper Sulphate (CuSO4тАЛтЛЕ5H2тАЛO).
For competitive exams, memorize the 'Vitriol' series: Blue = Copper, Green = Ferrous, White = Zinc. They are frequently tested in RRB and SSC exams.
