We kept the egg in the vinegar for forty-eight hours. On day two‚ we got our eggs out of the storing box thing‚ took the rubber band off‚ also the plastic wrap. We threw the plastic wrap away then poured the vinegar out of the cup. Took the egg out‚ and rubbed the shell off the egg because the vinegar deteriorated the shell

deaths per individual group and dividing them by the number of days the ants were studied for. The vinegar treated apple and normal apple death rates were determined by taking the average of each treatment variables death rates. For the ant tunneling rate‚ the total amount of tunneling done was divided by the number of days the study ran for. This number was then averaged for the normal apple and vinegar treated apple experimental groups. For both analyses the standard error and t-tests were performed

I chose this experiment because even though it is not the healthiest of snacks out there it is one of my favorites and I eat it almost everyday so I might as well get to know it a little better and do an experiment

Experiment 3: ANALYSIS OF UNKNOWN ACID SAMPLE USING TITRATION METHOD Date of Experiment: 4 September 2012 Introduction An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer
