calculate the oxidation no. of central atom of Kl3
Answers
Answer: KI3 is actually formed between K+ and I3- ions.
KI3 :- O. N. of Iodine in KI3 = +1+ (-3x) =
X=1/3 . Therefore the O. N. of iodine in KI3= 1/3 which is not possible. As O. N. cannot be
fractional.
We can consider the structure of KI3.
In I3 ion a co-ordinate bond is formed between I2 and I- ion.The ON of two iodine atoms is therefore
zero.The ON of iodine forming the co-ordinate bond is –1. Therefore the ON of iodine in KI3 is - 1.
Hope this helps you :)

If you don't want any explanation, directly jump to the end of the answer.To find oxidation state, you have to know following rulesThe value of oxidation state is determined by no of electrons shared, donated or gained.
If you don't want any explanation, directly jump to the end of the answer.To find oxidation state, you have to know following rulesThe value of oxidation state is determined by no of electrons shared, donated or gained.The sign of oxidation state is determined by the relative electronegativity of the constituent atoms.
If you don't want any explanation, directly jump to the end of the answer.To find oxidation state, you have to know following rulesThe value of oxidation state is determined by no of electrons shared, donated or gained.The sign of oxidation state is determined by the relative electronegativity of the constituent atoms.In KI3 , K donates one electron i.e. it is positively charged, so its oxidation state is +1 . Since the entire compound is neutral, the triiodide ion must be negatively charged i.e. it should have oxidation state as −1 & exist as I−3 ion.
