Sulfate ions can be used as Ligand Through one oxygen (monodentate) or two oxygens as a chelate or bridge.An example is complex [Co(en)2(SO4)]+Br- or neutral metal complexes PtSO4(P(C6H5)3)2, in which sulfate ions act as bidentate ligands.

What are examples of bidentate ligands?

The bidentate ligands have two donor atoms, enabling them to bind to the central metal atom or ion at two points.Common examples of bidentate ligands are Ethylenediamine (en) and oxalate ion (ox).

Is pyridine a bidentate ligand?

This Pyridine derivatives capable of acting as bidentate ligands, such as picolinic acid, prefer complexes that yield higher coordination numbers. A large number of complexes with various substituted pyridines are known. These complexes are known in the +1 and +3 states of Sc and Y.

Is water a bidentate ligand?

Water is a monodentate ligand because it contains oxygen with a lone pair of electrons. However, due to the presence of two lone pairs of electrons, it may appear that water is bidentate, but the bidentate ligand should have two different donor atoms. So, the answer is, Yes, water is the ligand.

Is sulfate a weak ligand?

First, hopefully the obvious things: Sulfate ions do form (weak) coordination bonds to the metallic center, thus causing some d-orbital splitting by definition.

What is the symbol for sulfate?

Sulfoxide anion obtained by deprotonation of the two OH groups of sulfuric acid.Sulfate or sulfate ion is a polyatomic anion with empirical formula SO2−4. Sulfates, acid derivatives and peroxides are widely used in industry.

Why does sulfate have 4 oxygens?

Sulfate is 4 single bonds.The difference in bond length is due to Sulfur has an extra charge, as does oxygen. This ionic bond will of course be shorter than the more neutral SO form.

What is the Difference Between Sulfur and Sulfate?

Sulfur is a chemical element, only sulfur and certainly not TOLL. … Sulfate is made from sulfur and oxygen. It is an anion with the chemical formula SO42-. It is the salt of sulfuric acid.

Why Sulfate 2?

Sulfur can have Partially positive charge or partially negative charge. Hydrogen sulfide = H2S, can be decomposed into H+ and HS- [sort of like water]. For 4 complete shells (8×4) we need 32 valence electrons, but only 30. Therefore, the charge of the ion is 2-.

Can sulfate exist alone?

Sulfate is naturally occurring polyatomic ions It consists of a central sulfur atom surrounded by four oxygen atoms, and its chemical formula is SO42-. …in fact, there are hundreds of minerals in the Earth’s crust that contain sulfates as one of their constituents.

What is the chemical formula of acetic acid?

Acetic acid, systematically named acetic acid, is an acidic colorless liquid organic compound with the chemical formula CH3COOH (Also written as CH3CO2H, C2H4O2 or HC2H3O2). The volume ratio of vinegar is not less than 4% acetic acid, so that acetic acid becomes the main component other than water in vinegar.

What is the symbol for sulfate radical?

Let us consider sulfate radical, the chemical formula is given by SO42−.

What color is sulfate?

Pure copper(II) sulfate is white. It is also called anhydrous copper(II) sulfate because it does not contain water. When water is present in a copper(II) sulfate sample, it turns blue.

Which is the strongest ligand?

On the other hand, ligands whose donor atoms are known to be carbon, phosphorus and sulfur are strong field ligands.According to this series $CO$ is the strongest ligand of the following because carbon is the donor in it, it has a double bond (C=O) and is positively charged.

Is Cl A a strong or weak ligand?

Halogen still acts as weak field ligand even in the case of a square plane [PtCl4]2− complex. A weak field doesn’t automatically mean high spin, nor does a strong field automatically mean low spin.

What is the molecular formula of sulfate radical?

The molecular formula for sulfate is SO42 .

What is sulfate used for?

Sulfate is used as a chemical detergent. They are found in household cleaners, detergents and even shampoos. There are two main types of sulfates used in shampoos: sodium lauryl sulfate and sodium lauryl ether sulfate. The purpose of these sulfates is to create a lathering effect to remove oil and dirt from the hair.

What is the pH of 10% acetic acid?

pH 4acidic.

What is the pH of acetic acid?

So, now we know that the pH of a 1 M acetic acid solution is 2.38.

Is acetic acid toxic?

Effects on humans: Acetic acid exists in vapor form Serious irritant to eyes, mucous membranes, upper respiratory tract and skin. In contact with skin or eyes, acetic acid solutions of 80% or higher may be corrosive, causing severe burns to any exposed tissue.

Why are sulfates bad for hair?

Sulfates help the shampoo remove oil and dirt from the hair. … Sulfates may take away too much moisture, making hair dry and unhealthy. They can also make the scalp dry and prone to irritation. Aside from a possible drying effect, sulfates pose little risk to human health when used correctly.

Which group is sulfate?

One group of derivatives consists of salts containing sulfate ions, SO42-and positively charged ions, such as those of sodium, magnesium, or ammonium; the second group consists of esters in which the hydrogen atoms of sulfuric acid have been replaced by carbon-containing binding groups such as methyl (…
