Disappearing Cross Experiment

The purpose of the experiment is to determine whether or not change magnitude temperature will increase the dictate of the reception. Reaction rate is a way of measuring how fast the answer takes place. So the high the reaction rate the faster the reaction takes place and the overthrow is the reaction time 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 theory states for a chemical reaction to occur particles need to collide at a plastered speed and angle. Increasing the temperature gives particles more energy, so they move faster. As they move faster more collisions happen, hence more productive collision, which increases the rate of the reaction1. Materials> Hydrochloric 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 also be concluded from the fact that it is the temperature that is changed in this experiment. The concentration and the amount of the reactants used argon the controlled variables, as they take away to stay constant throughout the experiment. Method of data sight It is important to carry out this experiment in a safe way, due to the fact that sodium thiosulphate and hydrochloric acid are being used. These liquids are highly dangerous as they can damage skin and eyes. To carry out the investigation in a safe way goggles and an apron were on all the time. The area where the experiment took place was cleaned before the experiment. The desk was whipped and any obstacles that...If you want to get a full essay, order it on our website: Ordercustompaper.com
