Disappearing Cross Experiment

The purpose of the experiment is to determine whether or not tack magnitude temperature pull up stakes increase the dictate of the reception. Reaction put is a way of meter how fast the answer takes rump. So the high the response rate the faster the reaction takes place and the overthrow is the reaction era is. Research Question How does reaction rate change with increasing temperature of atomic number 11 thiosulphate in a reaction between hydrochloric acid (HCl(l)) and sodium thiosulphate (Na2S2O3(l)) ? Hypothesis With increasing temperature of sodium thiosulphate the reaction rate will increase as well. apology As the collision speculation states for a chemical reaction to occur particles need to jolt at a plastered speed and angle. Increasing the temperature gives particles more(prenominal)(prenominal) energy, so they move faster. As they move faster more collisions happen, hence more productive collision, which increases the rate of the reaction1. Materials> Hy drochloric acid HCl(l)> sodium triosulphate Na2S2O3(l)> 250 ml3 beaker> 50 ml3 conical flask> 2 x 25 ml3 measuring cylinder> Thermometer> Stop clock> Tea kettle> coffer card> Pen Variables Reaction time is the dependent variable, as it depends on the temperature of the solution. The temperature of the solution is the independent variable, as it does not depend in whateverthing. This rout out as well be concluded from the fact that it is the temperature that is changed in this experiment. The concentration and the numerate of the reactants used argon the controlled variables, as they take away to persist constant throughout the experiment. Method of data sight It is cardinal to carry out this experiment in a unattackable way, due to the fact that sodium thiosulphate and hydrochloric acid are universe used. These liquids are highly dangerous as they can misuse skin and eyes. To carry out the investigation in a safe way goggles and an apron were on entirely the time. The a rea where the experiment took place was clea! ned before the experiment. The desk was whipped and any obstacles that...If you require to get a full essay, order it on our website: OrderEssay.net
