What happens to sodium thiosulphate when it is added to hydrochloric acid? How does the concentration effect the amount of sulphar produced?

Hydrochloric acid and thiosulphate be both clear liquids. They react to create sulphar, which if inhaled, back tooth be harmfal. When te experiemtn takes place get condone of the mixture as soon as it goes cloudy. A scramble must be drawn and the cone-shaped flaskful kick in away on top. The higher(prenominal) the concentration of thiosulphate the quiker the reaction becuase thither are more particles to react. The different concentrations of thiosulphate must be poored separetly into the conical flask containing 15cm3 of hydrochloric acid. When the mixture goes cloudy the raction stops. A stop look into should be used to time how long the reaction takes. On average it takes astir(predicate) 1 minute when the concentration is 50:50 and whewn 10:40 it takes 7 minutes. This shows that the higher the concentration the quiker the tot up of sulphar is produced.

Varying the temperature can also effect the amount of sulphar that is prduced. The rake of best fir would be curved showing that the higher the temperature the quiker the reaction. To make a fair test: keep the aforementioned(prenominal) concentration of water, sodium thiosulphate and hydrochlric acid.
