An investigation into the factors affecting the rate of a reaction: The write up of an experiment using Sodium Thiosulphate and hydrochloric acid

Skill Area P: Planning What I button to investigate is how dissimilar factors reach the rate of the chemical matchion of sodium Thiosulphate and Hydrochloric acid. In which a precipitate is formed and causes the solution to fail opaque. They react as in the equation on a lower floor: atomic number 11 Thiosulphate + hydrochloric acid -->; sodium chloride + sulphur + sulphur dioxide+ Water Na2S2O3(aq) + 2HCl(aq) -> 2NaCl(aq) + S(s) + SO2(g) + H2O(l) I plan to change the concentration of the Sodium Thiosulphate by diluting it with water system but I plan to cargo area the identical volume of liquid in the beaker to ensure that it is a comely test because the volume of liquid in the beaker may match the reaction time. Also in straddle to make it a fair test I am going to stay the spare-time activity variables the same: the temperature; the volume of the hydrochloric acid; the same focalize between the joyous detector and the solution; the same nutriment from t he flow source and the solution; the voltage going into the wake bulb; same concentration of acid; same beaker and contrivance; and the same total volume. I have identified the following hazards and I leave alone deal with them as shown below: Hazard 1: relations with Acids -- I give contain safety specs to comfort my eyes and care will be interpreted bit handling the acid. Hazard 2: Electrical Equipment - I will not touch the electrical equipment while handling liquids and care will be taken to make sure that all electrical equipment will not come into contact with liquids.

METHOD Equipment: A beaker Computer L ab-Pak electric discharge Source (I utiliz! e a 6V bulb)(Surround the light with a retrieve of black artificial to focus the light Light sensor (again surround the sensor with black artificial to irradiate light from other sources)... Experiments shouldnt be written in first person. As in I did this and I did that. It should be written a formal manner, Attach the light sensor to the clamp. The still exceptions are during the hypothesis and the Conclusion. Also when stating the regularity used do it in point form not as a paragraph If you want to get a in effect(p) essay, order it on our website: OrderCustomPaper.com
