Using An Agar Plate To Conduct Experiments
Using An Agar Plate To Conduct ExperimentsIn my Chemistry chapter, I talked about how to do experiments in chemistry. The way I did the experiment was to use a sample of the substance under investigation and cover it with a sheet of rubber so that I could control the amount of evaporation that took place. That way, I could put the reagent in an agar plate and run it through.This was done so that I would be able to get the right chemicals to work and have the sample work. The better the sample, the better the result would be. I took the sample out of the flask. I then covered it with the sheet of rubber.I threw the flask into the freezer. I found the sample with evaporation still running. I warmed it up a bit and put it into a bottle. When I removed the flask from the freezer, I could then test it to see what the result would be.The flask is on the table in front of me. I am testing a sample of sodium hydroxide. When I removed the flask from the freezer, I could see that the solid sam ple had dissolved, while the gas droplet was still around it.This was a good indication that some of the air bubbles in the solid sample had not fully dispersed. When I did this test, I found that the thing that I had put in the flask after the experiment, was actually a crystal of sodium hydroxide. I filled a glass and covered it with petroleum jelly. Then I placed the flask of sodium hydroxide in the glass and waited for it to freeze.When the liquid froze, I poured out the solution and dried it out. Now, I could see that the liquid was a simple solution. I shook it and allowed it to cool down and then looked at the sample.In this next chapter, I will talk about some more experimental methods and how to do them. I will talk about some of the things that you can do to the test. I will talk about different items that I used when conducting experiments. I hope that you enjoyed this chapter.
