Rate Of Reaction Lab Report

Rates of Reaction Disappearing Cross Experiment produce: To sense the estimate of chemical reaction atomic number 11 thiosulphate + hydrochloric dot ? atomic number 11 chloride + water + randomness dioxide + sulphur Equipment: conical flaskful 0.1M sodium thiosulphate 0.5M hydrochloric battery-acid 10ml measuring cylinder (x2) distilled water conical flask plosive speech sound watch paper thermometer mode: pour 10ml of 0.

5M hydrochloric acid into a conical flask place a moment of paper with a pencil cross haggard on underneath add the thiosulphate and start the stopwatch simultaneously stop the stopwatch wh en the cross has disappeared repeat with different solutions (see table below) Results: | intensity of thiosulphate |Volume of water/ml |Concentration of |Volume of acid/ml |Time for cross to disappear | |solution/ml | |thiosulphate (M) | |(minutes) | |10 |0 | |10 |2min 34 seconds | |8 |2 | |10 |3min 52 seconds | |6 |4 | |10 |7min 58 seconds | |4 |6 | ! |10 |11min 37 seconds | |2 |8 | |10 |15min 42 seconds | Tasks: 1. draw a graph to orient your results from divorce 1. 2. What conclusion can you draw about the set of intentness on rate of reaction? That thither is a condition relationship between the concentration and rate of reaction; as concentration of solvent increases, so too does the rate of reaction. 3. What problems/limitations were there with this method? The major problem was step 4 (stop the...If you emergency to get a full essay, order it on our website: BestEssayCheap.com
