Click on the flashcard to see the answer
What is a redox reaction?
A redox reaction is a chemical reaction that involves the transfer of electrons between species.
What are the two processes involved in a redox reaction?
Oxidation and reduction are the two processes involved in a redox reaction.
Define oxidation.
Oxidation is the loss of electrons or an increase in oxidation state.
Define reduction.
Reduction is the gain of electrons or a decrease in oxidation state.
What is an oxidizing agent?
An oxidizing agent is a species that causes oxidation by accepting electrons from another species.
What is a reducing agent?
A reducing agent is a species that causes reduction by donating electrons to another species.
What is the oxidation state of an uncombined element?
The oxidation state of an uncombined element is always zero.
In a redox reaction, the reducing agent is oxidized or reduced?
In a redox reaction, the reducing agent is oxidized.
In a redox reaction, the oxidizing agent is oxidized or reduced?
In a redox reaction, the oxidizing agent is reduced.
What is the reducing agent in the reaction: 2HCl + Zn → ZnCl2 + H2
The reducing agent in the reaction is Zn (Zinc).
What is the oxidizing agent in the reaction: 2HCl + Zn → ZnCl2 + H2
The oxidizing agent in the reaction is HCl (Hydrochloric Acid).
What is the oxidation state of hydrogen in most compounds?
The oxidation state of hydrogen in most compounds is +1.
What is the oxidation state of oxygen in most compounds?
The oxidation state of oxygen in most compounds is -2.
What is the oxidation state of any pure element?
The oxidation state of any pure element is always zero.
What is the oxidation state of an ion?
The oxidation state of an ion is equal to its charge.
