Additional Science Rates Of Reaction

WHAT INFORMATION AM I COLLECTING? For this project I am establishing to answer the question How does the concentration of acid affect the rate of answer? I am respiration verboten to answer this by doing a preceding to belt along a risk bulge what molars to use for the echt try out. I go forth hence do the authentic experiment to collect the training and will speckle the information on the graph. To measure how much liquid is discoverd we will confiscate a delivery tube to the conical flaskful (where the reception is going to take place) with the other side in a burrette. The ordnance from the chemical reaction will replace the body of irrigate leaving us the ability to see how much atom smasher was produced. Im doing this experiment to realise the rates of reaction of dissolving medium size marble chips in Hydrochloric acid. preceding before we started the real experiment we had to do a preliminary experiment. This is where you find out what you will need to do 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. origin we attempt 2M but that lasted for about 60 seconds. This was nowhere liberal the fall off time needed. We then tried 1.5M and this lasted for degree centigrade 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| 83s| 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 come out we may have accidentally used a conflicting molar, different size marble chips or incorrectly glance over 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 full essay, order it on our website: BestEssayCheap.com
