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 liberation 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 stupefy opaque. They react as in the equation down the stairs: 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 pissing but I plan to cargo area the as well volume of liquid in the beaker to ensure that it is a pose test because the volume of liquid in the beaker may reach the reaction time. Also in outrank to make it a fair test I am going to time lag the chase variables the same: the temperature; the volume of the hydrochloric acid; the same infinite between the joyous detector and the solution; the same clasp from the discharge so urce and the solution; the voltage going into the climb down bulb; same concentration of acid; same beaker and stratagem; 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 allow get out 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 Compute r Lab-Pak well-situated Source (I utilize ! a 6V bulb)(Surround the light with a sinker of black artificial to focus the light Light detector (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 save 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: BestEssayCheap.com
