Pilot test In the pilot test Imp going to try to find about the best way to tear the chemical reactions Darning the pilot test I will try to experiment the reactions and come to a conclusion of this coursework I will change concentration to start with I will start by using 2 molars of HCL and 015 molar of NaS2O3 I will do two tests 1 2m HCL 10cm3 015m NaSa 20 cm3 2 1m HCL 5 cm 3 2 m 5cm33 water 015m NaS2O3 20cm3 Amount of HCL cm3 Amount of NaS2O3 cm3 Time SecAmount of Water H20 cm3 10 cm320 cm33234 sec0 cm3 5 cm320 cm34252 sec5 cm3 The result show that when the substances more concentrated with HCL the reaction speeds up I know this because because when I used 2 molars of HCL and 10 cmof it the reacted with a time of 3234 seconds However when I used 1 molar of hcl and 5 cm3 Hcl with 5 cm3 of H20 It took longer for the X to not be seen and therefore suggesting that it was slower as its time was 4252 seconds In my opinion the concentrated solution reacted quicker with the thio sulphate solution because when it was more concentrated it meant that there were more particles ofKnocking about between the water molecules This then makes collisions of important particles more likely If they then they would also be more likely to react particles are more likely For this reason an increase of concentration 65532
