What is the another name for blue vitriol?

Cupric sulfate, CuSO4, commonly known as blue vitriol, is the most important salt of copper.

Why the colour of blue vitriol is blue?

Blue vitriol is blue in colour because it absorbs all the wavelengths in visible light and reflects only that part of spectrum having wavelength of blue light.

What is the other name of copper sulphate?

Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5. The pentahydrate (x = 5) is the most common form. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol.

What is the shape of blue vitriol crystal?

The four oxygen atoms about each sulphur atom are arranged in a tetrahedron, the same shape as a pyramid-shaped teabag. The six oxygen atoms around the copper atom are in an octahedron – one at the top, one at bottom, and four in a square around the middle.

What is the symbol of Blue vitriol?

CuSO4
Copper(II) sulfate/Formula

Which one of the given is commonly known as Blue vitriol and is used as a fungicide?

The correct answer is option 1, i.e. Cu. It is used as a fungicide.

Why does blue vitriol changes to white upon heating give the chemical equation involved?

Blue vitriol is hydrated Copper(II) Sulphate, meaning CuSO4. When blue vitriol is heated, those water of crystallization escape out of the crystal and what’s left is anhydrous copper sulphate or simply CuSO4, without any water of crystallization.

Is copper a sulfate?

Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. Copper is an essential mineral. It can be found in the environment, foods, and water.

What is blue vitriol used for?

Blue vitriol is soluble in water, and is a very important industrial salt of copper. It is used in insecticides and germicides, in electrolytes for batteries, and in electroplating baths.

What is a green vitriol?

Ferrous sulphate or iron(II) sulphate is most commonly encountered as the blue-green heptahydrate, known since ancient times as copperas or green vitriol. Ferrous sulfate can be found in various states of hydration, and several of these forms exist in nature. The formula is FeSO4. 7H2O. It occurs in nature as copperas.

Is copper sulfate harmful to humans?

Copper sulfate can cause severe eye irritation. Eating large amounts of copper sulfate can lead to nausea, vomiting, and damage to body tissues, blood cells, the liver, and kidneys. With extreme exposures, shock and death can occur. Diarrhea and vomit may have a green to blue color.

What is Blue vitriol used?

a salt, copper sulfate, CuSO4⋅5H2O, occurring naturally as large transparent, deep-blue triclinic crystals, appearing in its anhydrous state as a white powder: used chiefly as a mordant, insecticide, fungicide, and in engraving.

What happens when blueblue vitriol is heated?

Blue Vitriol is Penta hydrated copper sulphate. On heating at 100oC it loses 4 molecules of crystallization. At 230oC, it loses 5th molecules of water and becomes white amorphous powder. The powder again becomes blue in presence of water. It undergo dissociation on strong heating.

What is blue vitriol made of?

blue vitriol. noun Chemistry, Mineralogy. a salt, copper sulfate, CuSO4⋅5H2O, occurring naturally as large transparent, deep-blue triclinic crystals, appearing in its anhydrous state as a white powder: used chiefly as a mordant, insecticide, fungicide, and in engraving.

Why are buildings in Greece painted in blue and white?

It wasn’t until 1967, when a military government was in power in Greece, that the other colors disappeared for good. Thinking that the blue and white showed unification, and supported their political agenda, this government mandated that all buildings must be repainted in blue and white if they weren’t already.
