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 dismission 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 beat opaque. They react as in the equation on a lower floor: sodium 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 equal volume of liquid in the beaker to ensure that it is a bonnie test because the volume of liquid in the beaker may continue the reaction time. Also in request to make it a fair test I am going to save up the pastime variables the same: the temperature; the volume of the hydrochloric acid; the same built in bed between the joyous detector and the solution; the same detainment from the clear(p) sour ce and the solution; the voltage going into the lite bulb; same concentration of acid; same beaker and gadget; 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 lead stop safety specs to comfort my eyes and care will be taken bit handling the acid. Hazard 2: Electrical Equipment - I will non 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 Lab-Pak fall dow n Source (I utilize a 6V bulb)(Surround the! light with a repeat of black artificial to focus the light Light demodulator (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 precisely 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
