Precipitate and Solutions Labs Precipitate Lab: Our group had to mix solutions in this lab, and see what happened. To see if a chemical reaction occurred, we just had to look for a color change. All the solutions were clear, so spotting a color change was pretty easy. We put drops on an overhead paper and mixed each solution with all the other solutions. But, we didn’t know why a color changed occurred. We were told that it was because a precipitate formed, yet we didn’t know what a precipitate was. Not all of the solutions changed color either. Why do some solutions change color and others don’t? How does a precipitate form? How do you know if a precipitate will form? What is a precipitate? After doing this lab, we learned all about what precipitates are and how/why they form. First of all, a precipitate is an insoluble substance that falls out of solution. When two solutions are mixed, it’s possible for a precipitate to form, because the solutions contain ions. When these ions combine, sometimes they form precipitates. The

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
