* General Rules:
* The oxidation state of chlorine (Cl) is usually -1, except when combined with oxygen or fluorine.
* The sum of the oxidation states in a neutral molecule must equal zero.
* Applying the Rules:
* Let the oxidation state of iodine be 'x'.
* The oxidation state of chlorine is -1.
* The overall charge of ICl is 0.
* Equation:
x + (-1) = 0
* Solving for x:
x = +1
Therefore, the oxidation state of iodine (I) in ICl is +1.
