You will 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:
Why is the reaction that occurs when lead (II) nitrate and potassium iodide mix called a precipitation reaction?
~ The reaction is called a precipitation reaction because when lead (II) nitrate and potassium iodide solutions are mixed together, they form an insoluble compound or precipitate which is made of lead (II) iodide.
What two products are usually produced by a neutralization reaction? What is another name for this type of reaction?
~ Neutralization reactions usually produce ionic compounds and water. Another name for a neutralization reaction is an acid-base reaction.
Explain what occurs during an oxidation-reduction reaction.
~ During an oxidation-reduction reaction, electrons are transferred between two reactants.
Describe the chemical reaction that occurs when magnesium interacts with oxygen. What type of chemical reaction occurs when these materials interact?
~ When magnesium and oxygen interact, the magnesium produces a bright, white flame. This type of reaction is called a combustion reaction. Moreover, the reaction is an oxidation-reduction reaction because electrons are transferred between oxygen and magnesium. Magnesium gives two electrons to oxygen, so magnesium's oxidation number rises from 0 to 2. In other words, magnesium is oxidized. At the same time, oxygen's oxidation number falls from 0 to -2. In other words, oxygen is reduced.
