Aim investigate the factors effecting the rate of reaction between sodium thiosulphate and hydrochloric acid
Reactions occur when particles collide the more often they collide then the faster the reaction. There is a huge difference between the rates of different reactions. Increasing the energy or frequencies of collisions between the particles can increase the rates of reactions. The rate of the reaction depends on four factors The surface area of the reactants that are solid A larger surface area means that there is more chance of a collision-taking place. But as we are using both liquids in our reaction the factor does not affect us. ... This will increase the number of collisions per second so increase the rate of reaction. ... Light Light energy helps reactions such as photosynthesis to increase in rate. Catalyst A catalyst is a substance that increases the rate of reaction, but does not change, itself. For this investigation we will study how the concentration affects the rate of reaction. ... To do investigate this we will watch the precipitate of sulphur appear. ... Then add a controlled amount of Sodium thiosulphate. ... We are unable to do the experiment the preferred five times as we dont have enough time To test that our method works we will do a pilot test HcL Na2S2O3 Reaction time (sec) 20 20 0.
