Chapter 4, Problem 95b
What is the oxidation state of Cr in each compound? b. CrO3
Verified step by step guidance1
Identify the oxidation state of oxygen in the compound. Oxygen typically has an oxidation state of -2.
Let the oxidation state of chromium (Cr) be x.
Write the equation for the sum of oxidation states in the compound: x + 3(-2) = 0, since the compound is neutral.
Simplify the equation: x - 6 = 0.
Solve for x to find the oxidation state of chromium in CrO3.
Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Oxidation State
The oxidation state, or oxidation number, is a value that represents the total number of electrons an atom either gains or loses when it forms a compound. It helps in understanding the electron transfer in redox reactions and is crucial for determining the reactivity and stability of compounds.

Oxidation Numbers
Rules for Assigning Oxidation States
There are specific rules for assigning oxidation states, such as the oxidation state of an element in its standard state is zero, the oxidation state of a monoatomic ion equals its charge, and in compounds, the sum of oxidation states must equal the overall charge of the compound. These rules guide the determination of oxidation states in various compounds.

Chromium Compounds
Chromium can exhibit multiple oxidation states, commonly ranging from -2 to +6. In compounds like CrO3, chromium typically has a +6 oxidation state, which is important for understanding its chemical behavior and applications, particularly in oxidation reactions and industrial processes.
