WHAT INFORMATION AM I COLLECTING? For this project I am showing to answer the question How does the concentration of naughty affect the rate of answer? I am animate verboten to answer this by doing a approach to digest a risk bulge what molars to use for the reliable try out. I go forth hence do the in truth experiment to collect the learning and will speckle the information on the graph. To measure how much liquid is discoverd we will enlarge a delivery tube to the conical flaskful (where the reception is going to take place) with the other side in a burrette. The bollix up from the reaction will replace the body of piddle leaving us the ability to see how much burn out was produced. Im doing this experiment to come on the rates of reaction of dissolving medium size marble chips in Hydrochloric acid. antecedent before we started the real experiment we had to do a preliminary experiment. This is where you find out what you will need to d o for the real experiment and what conditions we will be working in. We needed to find out what molar of hydrochloric acid we were going to use in our experiment. We valued the acid to last for about 300 seconds. front we attempt 2M but that lasted for about 60 seconds. This was nowhere draw near the fall off time needed. We then tried 1.5M and this lasted for coke seconds. Still non long enough. We next tried 1M and this lasted for about cxxx seconds.
We then tried 0.5M and it lasted for 330 seconds. This was good so we then utilise 0.2M, 0.4M, 0.6M, 0.8M and 1M for the experiment. 0.5M| 1M| 1.5M| 2M| 1| 332s| 120s| 83 s| 56s| 2| 330s| 118s| 92s| 30s| 3| 240s! *| 134s| 111s| 30s| 4| 344s| | | 77s*| Time it took until 50cm³ of gas was produce^ *these are most likely anomalies in the results. For this to incur we may have accidentally used a contradictory molar, different size marble chips or incorrectly immortalise the burrette. EQUIPMENT USED * tub (old ice cream tub) this held the water at the bottom of the experiment. * fasten this...If you want to get a plentiful essay, order it on our website: BestEssayCheap.com
