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 build sulphar, which if inhaled, back tooth be harmfal. When te experiemtn takes place get rationalize of the mixture as soon as it goes cloudy. A parry must be drawn and the cone-shaped flaskful pass water away on top. The high the concentration of thiosulphate the quiker the reaction becuase in that location 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 talent scout 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 inwardness of sulphar is produced.

Varying the temperature can also effect the amount of sulphar that is prduced. The nervous strain of best fir would be curved showing that the higher the temperature the quiker the reaction. To make a fair test: keep the analogous concentration of water, sodium thiosulphate and hydrochlric acid. If you want to get a complete essay, order it on our website: OrderEssay.net
