Chemical engineers use special reactions called single replacement reactions in many important ways, especially for getting metals out of the ground and cleaning up wastewater. Let’s break down how they do this:

1. Metal Extraction:

   • In this process, a more active metal can push a less active metal out of a compound.
   • For example, if you use zinc, it can take copper out of copper sulfate.
   • This method is really important in mining because it helps recover valuable metals.

2. Wastewater Treatment:

   • Engineers also use these reactions to get rid of unwanted metals in water.
   • They replace harmful metals with safer materials.
   • This helps clean the water so it can be safe for people to drink.

Single replacement reactions play a big role in making these processes work well and are better for the environment!
