Below is a short sample of the document. Visit Coursework.info for the full version.
I repeated this process again for 0.5 molar acid, 0.75 and 1 molar acid. I kept the volume of acid and the mass of limestone the same for each experiment as to keep it a fair test.
Then I repeated the entire process again 3 times so that I could get average results. During my experiment I managed to control all the variables to the best of my ability. I recorded all my results in a table, which you can also see later on in the coursework, and using the results I will also draw a graph. Results
