Today we had a cool lab that involved mixing various compounds and seeing if a reaction occurred, forming a precipitate. Here's a photo of the well plate after a few solids formed.
As you can see, there's a difference in color in the solution in numbers 2, 3, 11(supposed to be 4), 5, 6, and 7. This means that a reaction occurred and a solid formed in the solution. 2, 3, and 4 are a very milky and cloudy reaction, while 5,6, and 7 are a bright vibrant blue color with almost snake-like formations. What surprised me the most during this lab was how vibrantly some solutions reacted, while at the same time other solutions didn't react at all. It was very cool seeing the precipitate form.
All the balanced chemical reactions for numbers 1-10 are written out on this piece of paper below. You can see if a reaction occurred if a solid (s) is written in the products.
Here are the net ionic equations for any chemical reaction in which the solid precipitate formed.
