Types of Chemical Reactions Lab
Intro/Purpose
The purpose of this lab is to determine types of reactions with only the reactants and through observation. Through observing the experiments, one is able to see a visual of each type of reaction taking place and it gives them a better understanding of how chemical reactions work and what products they may form.
Materials & Procedure
Materials:
* Wood Splints - Copper Sulfate * Sodium Sulfate - Copper Wire * Barium Chloride - 6% Hydrogen Peroxide * Mossy Zinc - Copper Sulfate Pentahydrate * Hydrochloric Acid - Iron Filings * Manganese Dioxide
Procedure:
Reaction A
Place a scoop of copper (II) sulfate pentahydrate crystals in a clean, dry test tube. Use a test tube holder to position the test tube over a burner flame. Heat until no further change is observed. Allow dehydrated crystals to cool and add 5 drops of water.
Reaction B
Place 1 squirt of sodium sulfate in a test tube. Add a squirt of barium chloride solution.
Reaction C
Using crucible tongs, heat a 5 cm piece of copper wire to red heat for 30 seconds in the hottest part of the burner flamer. After the wire cools, scrape its surface with the edge of a scoopula.
Reaction D
Place a small piece of mossy zinc in a test tube and add enough hydrochloric acid so that the mossy zinc is completely submerged. Then insert a burning splint into the mouth of the test tube.
Reaction E
Fill one third of a test tube with hydrogen peroxide. Use a scoopula to add a match head sized amount of manganese dioxide. Then insert a glowing splint into the mouth of the test tube.
Reaction F
Place iron filings in a test tube and cover them with copper (II) sulfate solution. After several minutes, pour off the liquid, dump out the iron filings and examine them.
Observations
