Capitolo 13, Problema 57
What is the oxidation state of each element in the compound Ca3SiO5?
Guida verificata passo dopo passo1
Identify the oxidation state of calcium (Ca). Calcium is an alkaline earth metal, typically having an oxidation state of +2.
Identify the oxidation state of oxygen (O). Oxygen usually has an oxidation state of -2.
Let the oxidation state of silicon (Si) be x.
Write the equation for the sum of oxidation states in the compound: 3(+2) + x + 5(-2) = 0.
Solve the equation for x to find the oxidation state of silicon.
Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
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 chemical bond. 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 elemental form is zero, oxygen typically has an oxidation state of -2, and alkali metals have an oxidation state of +1. These rules guide the determination of oxidation states in compounds.

Sum of Oxidation States
In a neutral compound, the sum of the oxidation states of all the elements must equal zero. This principle is essential for calculating the oxidation states of individual elements in a compound, as it ensures that the overall charge of the compound is balanced.
