TYPES OF CHEMICAL REACTIONS
Introduction
In this experiment you will study six different chemical reactions. You will classify each chemical reaction as one of four types:
● Synthesis
● Decomposition
● Single Displacement
● Double Displacement
You Will Need
● 6 test tubes
● test tube rack
● 2 droppers
● 3 beakers
● magnesium ribbon
● iron filings
● hydrochloric acid
● sodium hydroxide
● sodium sulfate
● barium chloride
● copper sulfate
● hydrogen peroxide
● manganese dioxide
What You Will Do
1. Label number each test tube from 1 to 6.
2. Place a small amount of sodium sulfate solution into test tube 1. Add a dropper full of barium chloride solution. Record the results.
3. Place a small piece of magnesium ribbon into test tube 2. Add a small amount of hydrochloric acid to the test tube. Record results.
4. Add a small amount of iron filings into test tube 3. Cover the iron filings with a small amount of copper sulfate. Gently shake the test tube. Record the results.
5. Take test tube 4 and obtain a small amount of hydrogen peroxide from the teacher. Add a tiny amount of manganese dioxide. Record the results.
6. Take test tube 5 and obtain a small amount of sodium hydroxide from the teacher. Add a drop at a time of hydrochloric acid until the solution is clear. (No longer pink.) Record the results.
7. Place a small amount of copper sulfate into test tube 6. Add a small amount of sodium carbonate to the test tube. Record the results.
8. Return your utensils to you teacher for clean up.
