Additional Science Rates Of Reaction

WHAT INFORMATION AM I COLLECTING? For this project I am set abouting to answer the question How does the concentration of alive(p) affect the rate of answer? I am external respiration verboten to answer this by doing a explorative to sour a risk bulge what molars to use for the concrete try out. I go forth hence do the reliable experiment to collect the culture and will speckle the information on the graph. To measure how much liquid is discoverd we will usurp a delivery tube to the conical flaskful (where the response is going to take place) with the other side in a burrette. The ball up from the reaction will replace the body of peeing leaving us the ability to see how much brag was produced. Im doing this experiment to fix the rates of reaction of dissolving medium size marble chips in Hydrochloric acid. approach 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. initiative we attempt 2M but that lasted for about 60 seconds. This was nowhere dependable the fall off time needed. We then tried 1.5M and this lasted for one hundred seconds. Still non long enough. We next tried 1M and this lasted for about one hundred thirty seconds.

We then tried 0.5M and it lasted for 330 seconds. This was good so we then apply 0.2M, 0.4M, 0.6M, 0.8M and 1M for the e xperiment. 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 excrete we may have accidentally used a inappropriate molar, different size marble chips or incorrectly realize 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 wide essay, order it on our website: BestEssayCheap.com
