Questions & Step-by-Step Solutions
In the reaction 2Ag^+ + Zn → 2Ag + Zn^2+, what is the oxidation state change for zinc?
Step 1: Identify the reactants in the reaction, which are 2Ag^+ and Zn.
Step 2: Determine the oxidation state of zinc (Zn) in its elemental form. Elemental zinc has an oxidation state of 0.
Step 3: Look at the products of the reaction, which include Zn^2+. This indicates that zinc has lost electrons.
Step 4: Identify the oxidation state of zinc in the product Zn^2+. The oxidation state of Zn^2+ is +2.
Step 5: Calculate the change in oxidation state for zinc. It goes from 0 to +2, which is an increase of 2.
Oxidation and Reduction – Understanding how oxidation states change during a chemical reaction, specifically identifying which species is oxidized and which is reduced.
Oxidation States – Knowledge of the oxidation states of elements in compounds and how to determine them based on the reaction.
