Effect of tempreature on sodium thiosulphate

Introduction and Preliminary Results. There atomic number 18 five factors which affect the rate of a chemical reaction, consort to the collision theory of reacting particles: temperature, dousing (of response), pressure (in gases), draw cultivation argon (of solid reactants), and catalysts. I have chosen to canvass the effect temperature and concentration have on a reaction. This is because they argon the most practical to investigate - it would take longer to detect a solid in powdered and solid form, and it is operose to stool accurate readings due to the inevitabilities of human errors. Gas is generally color slight and it is heavy to measure a reaction changing the pressure, and if a substance is added to give the gas colour, it may fascinate the publication of the experiment. Similarly, the use of a catalyst complicates things, and if used incorrectly it could deviate the outcome of the experiment. A reaction, basically, takes place when there are favored c ollisions between the particles of the reactants involved. The much capability that is face up in reaction, the quicker it will be, as the particles involved stern shake more success skillfuly. If there is a higher concentration of the reactants present, thriving collisions are increased because there are more particles present in them. If a catalyst is added, the particles need less energy to collide successfully, also increasing the reaction speed.

some(prenominal) reaction can be speeded up if the number of successful collisions can be increased. For this assignment, we investigated and the different fact ors that affect the rate of a reaction. I ch! ose hydrochloric acid (HCl) and sodium thiosulphate (N2 S2 O3) as my reactants. When sodium thiosulphate and hydrochloric are mixed, a yellow precept of due south is produced. The solution becomes increasingly difficult to see through as more and more sulphur is formed.
