Alum Lab
The lab that I have completed has many important factors within it. Theory to application is one factor that you deal with in this lab. Also, you use mass-mass calculation and quantitatively to evaluate the lab and calculate the yield. Some of the basics in this lab are learning more about acids and bases along with practicing lab safety techniques. When you are dealing with mass-mass calculations you will always have the expected value and your value. By doing this you are able to use both of these values to calculate your deviation and percent loss in the easiest way I have been taught. I however think that when using mass-mass calculations there is a risk for error. When you make a mass-mass calculation you do them one step at a time. Then when proceeding to the next step you will use your previous value that you have just found and plug it into your next equation. I think that by using a process like this one, you have a very high chance of error. All you have to do is make one miscalculation or transfer of a nu
42g and in table 2 the deviation is -6. In conclusion, I think that this lab helped me gain an understanding how theory to application really works. For example, in table 1 the %yield is 7. Einstein expressed this relationship in his famous equation: E=mc^2" (Smoot, Robert; Price, Jack; Smith, Richard. When you compare the results of table 1 and table 2 you will find some differences. mber from a equation to another and it will ruin the whole problem. Therefore concluding that the higher your yield is the mass of the alum will rise. Instead of only having to make one correction you would most likely have to redo the problem because of the step by step process it would affect the whole problem. He also showed that energy can be changed to matter.
