Understanding Oxidation State

Oxidation state is a measure of the degree of oxidation of an atom in a compound. It is a way to keep track of the transfer of electrons in a chemical reaction. The oxidation state of an atom is determined by the number of electrons it has gained or lost. In a compound, the sum of the oxidation states of all the atoms must equal the charge on the compound.

Rules for Assigning Oxidation State

There are several rules for assigning oxidation state to an atom in a compound:

  • The oxidation state of an element in its elemental form is 0.
  • The oxidation state of a monatomic ion is equal to its charge.
  • The oxidation state of oxygen is usually -2, except in peroxides where it is -1.
  • The oxidation state of hydrogen is usually +1, except in hydrides where it is -1.
  • The sum of the oxidation states of all the atoms in a compound must equal the charge on the compound.

Determining the Oxidation State of Cl in HClO3

To determine the oxidation state of Cl in HClO3, we need to apply the rules for assigning oxidation state. We know that the oxidation state of oxygen is usually -2, and the oxidation state of hydrogen is usually +1. Since there are three oxygen atoms in HClO3, the total oxidation state of oxygen is -6. The oxidation state of hydrogen is +1.

Calculating the Oxidation State of Cl

Let's calculate the oxidation state of Cl in HClO3. We know that the sum of the oxidation states of all the atoms in a compound must equal the charge on the compound. The charge on HClO3 is -1 (since it is a weak acid). We can set up an equation to represent this:

H + Cl + 3O = -1

We know that the oxidation state of hydrogen is +1, and the oxidation state of oxygen is -2. We can substitute these values into the equation:

+1 + Cl + 3(-2) = -1

Simplifying the equation, we get:

+1 + Cl - 6 = -1

Combine like terms:

Cl - 5 = -1

Add 5 to both sides:

Cl = +4

However, this is not the correct answer. We need to consider the fact that the oxidation state of oxygen is usually -2, but it can be different in certain cases. In this case, we need to consider the fact that the oxidation state of oxygen can be -1 in peroxides.

Revising the Oxidation State of Cl
