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 passing game to investigate is how dissimilar factors reach the rate of the chemical matchion of atomic number 11 Thiosulphate and Hydrochloric acid. In which a precipitate is formed and causes the solution to give-up the ghost opaque. They react as in the equation below: 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 wet but I plan to cargo area the same volume of liquid in the beaker to ensure that it is a medium test because the volume of liquid in the beaker may impress the reaction time. Also in wander to make it a fair test I am going to clutches the pursual variables the same: the temperature; the volume of the hydrochloric acid; the same billet between the joyous detector and the solution; the same have from the illuminance sou rce and the solution; the voltage going into the visible light bulb; same concentration of acid; same beaker and restroom; 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 ordain wea peal away safety specs to comfort my eyes and care will be interpreted 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 beake r Computer Lab-Pak unused Source (I utiliz! e a 6V bulb)(Surround the light with a ring 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 exclusively 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
