Lab to demonstrate a few typical single replacement reactions. Each reaction can be physically viewed.
The first reaction involves dissolving copper sulfate in solution and then hanging a strip of zinc into it. Note all initial colors and final color changes.
The second involves a reaction between zinc and hydrochloric acid.
The gas produced can be seen bubbling from the solution, and then is collected in an inverted test tube over the mouth of the generator.
The gas produced is tested with a burning splint placed under the mouth of the inverted tube.
The reaction is noted and discussed. Aiden works well in the lab. We discussed what happened to the Hindenburg in light of the reaction of the hydrogen with a flame.
