You get to know the major kinds of chemical reactions including polymerization, hydrolysis, combustion, replacements, and redox. Experiment with some electrochemical reactions as well.
After completing this tutorial, you will be able to complete the following:
What happens to the zinc and the copper in the oxidation reaction?
~ In the oxidation reaction, the oxidation state of zinc increases from 0 to 2+, while the oxidation state of copper decreases from 2+ to 0. For every mole of zinc, two electrons are transferred to the copper during the reaction.
What is the difference between an oxidation reaction and a reduction reaction?
~ In an oxidation reaction, the oxidation state of a substance increases by releasing electrons. In a reduction reaction, the oxidation state decreases because electrons are gained.
In a redox reaction, what role does the reducing agent play?
~ In a redox reaction, the reducing agent causes reduction by providing electrons to another substance. The reducing agent contains the atom that shows an increase in oxidation number.
In a redox reaction, what role does the oxidizing agent play?
~ In a redox reaction, the oxidizing agent is the substance that causes the oxidation of another substance by accepting its electrons. The oxidizing agent contains the atoms that show a decrease in oxidation number.
