Hello all,
i am new to this forum and this is my first time posting, I have been assigned some coursework in chemistry that requires me to look into rates of reaction and what effects the reaction.
This is the study brief:
One chemical that is made industrially is sodium thiosulfate. Sodium thiosulfate solution is sold in a range of concentrations. Dilute solutions of sodium thiosulfate can be used for cleaning contact lenses and used as a medicine for some cancer patients. Concentrated solutions are used to treat spillages of some chemicals.
Sodium thiosulfate is safe to handle and store, but if it is mixed with an acid, a reaction happens. When dilute sodium thiosulfate is mixed with an acid, solid sulfur is made, which makes the solution appear cloudy. The reaction also makes small amounts of toxic sulfur dioxide gas.
You will choose one factor (Either temperature or concentration)and investigate this factor's effect on the rate of reaction between sodium thiosulfate and dilute hydrochloric acid.
Well, that was what i was asked to do, i appreciate any help that you guys can give me and help me to achieve a good grade.
THe study will be presented as a number of documents containing pictures, information from external sources and our results of our own and a conclusion.
Thanks in advance!
