What is the oxidation state of iodine in KIO3?

So oxidation number of I in KIO3 is 5. Was this answer helpful?

Why does I3 exist but not f3?

Answer. When we see the lewis dot structure of both the elements below, we can see F2- has octet structure, I3- has more electrons than octet. Some elements can afford more electrons than octet structure. This is because Iodine has d orbital in its electronic configuration, where as Florine doesnot.

Is I3 linear or bent?

linear
I3- molecular geometry is linear. While there are three Iodine atoms, one of the atoms has a negative charge which further gives 3 lone pairs of electrons and 2 bond pairs. Its steric number will be 5. The three lone pairs will repel each other and take up equatorial positions.

What is the oxidation number of niso4?

+2
Nickel(II) sulfate, also known as nickelous sulfate, is a chemical compound. Its chemical formula is NiSO4. It contains nickel in its +2 oxidation state.

Can iodine form I3+?

Due to the presence of vacantd-orbitals I2 accepts electrons from I- ions to form I3- ions butbecause of absence of d-orbitals F2 does not accept electrons from Fions to form F3- ions.

Why does I3 violate octet rule?

Lewis Dot of Triiodide Ion I3- I does not follow the octet rule. It will hold more than 8 electrons. Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons.

Is I3 negative linear?

I3- Molecular Geometry And Bond Angles I3- molecular geometry is linear. While there are three Iodine atoms, one of the atoms has a negative charge which further gives 3 lone pairs of electrons and 2 bond pairs. Its steric number will be 5.

What is the formula for triiodide?

In chemistry, triiodide usually refers to the triiodide ion, I− 3. This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine. Some salts of the anion have been isolated, including thallium (I) triiodide (Tl + −) and ammonium triiodide (+ −).

How many iodine atoms are in thallium triiodide?

This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine. Some salts of the anion have been isolated, including thallium (I) triiodide (Tl + [I 3] −) and ammonium triiodide ( [NH 4] + [I 3] − ).

What is the colour of triiodide?

Triiodide is observed to be a red colour in solution . Other chemical compounds with “triiodide” in their name may contain three iodide centers that are not bonded to each other as the triiodide ion, but exist instead as separate iodine atoms or iodide ions.

What is the composition of the ionic compound with iodine triiodide?

Lugol’s iodine contains potassium iodide and a stoichiometric amount of elemental iodine, so that significant amounts of triiodide ion exist in this solution. Tincture of iodine, although nominally a solution of elemental iodine in ethanol, also contains significant amounts of triiodide, due to its content of both iodide and water.
