Introduction this is an investigation about the decomposition of sodium thiosulphate there are many factors (variables) which determine how fast or slow the reaction can take place (rate of reaction) these are: initial volume of sodium thiosulphate the initial volume of hydrochloric acid the initial volume. The reaction of sodium thiosulfate and hydrochloric acid generates sulfur dioxide gas, which is a skin and eye irritant perform this demonstration in a well- ventilated lab only avoid contact of all chemicals with eyes and skin wear chemical splash goggles, temperature-resistant gloves, and chemical-resistant apron please. When a chemical has a greater concentration of molecules the chances of successful collisions increases and therefore speeds up the reaction the hydrochloric acid - sodium thiosulphate reaction depends on the time for a certain amount of sulphur precipitate to form and obscuring a marked black x on white paper.
