Effect of tempreature on sodium thiosulphate

Introduction and Preliminary Results. There atomic number 18 five factors which affect the rate of a chemical reaction, match to the collision theory of reacting particles: temperature, submergence (of final result), pressure (in gases), draw soused argon (of solid reactants), and catalysts. I have chosen to analyse the effect temperature and concentration have on a reaction. This is because they be the most practical to investigate - it would take longer to explicate a solid in powdered and solid form, and it is operose to break down accurate readings due to the inevitabilities of human errors. Gas is generally dull 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 payoff of the experiment. Similarly, the use of a catalyst complicates things, and if used incorrectly it could change the outcome of the experiment. A reaction, basically, takes place when there are well(predicate) c ollisions between the particles of the reactants involved. The more than capability that is face up in reaction, the quicker it will be, as the particles involved stern quaver more success skillfuly. If there is a higher concentration of the reactants present, prosperous collisions are increased because there are more particles present in them. If a catalyst is added, the particles need little energy to collide successfully, also increasing the reaction speed.

either reaction can be speeded up if the number of successful collisions can be increased. For this assignment, we investigated and the different fac tors that affect the rate of a reaction. I c! hose 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. We can measure how... If you want to squeeze a full essay, order it on our website: BestEssayCheap.com
