Chemistry-C6-Rate of Reaction: Concentration 0.0 / 5 ? ChemistryRate of reactionGCSEAQA Created by: tonisha_Created on: 19-04-22 15:38 The higher the concentration of the acid, the? faster the rate of reaction 1 of 25 This is because in the acid with the high concentration, there are more? H+(hydrogen) ions present 2 of 25 This means that there will be more? frequent and successful collisions 3 of 25 Due to the fact that more? hydrogen ions are present 4 of 25 Disappearing Cross -------------------------- Firstly use a? measuring cylinder 5 of 25 to put some sodium thiosulfate into? a conical flask 6 of 25 Then place the conical flask? on to a printed black cross 7 of 25 Then add some what into where? add some HCl into the conical flask 8 of 25 Then do what to the solution? swirl it 9 of 25 And start? a stopwatch 10 of 25 What should be produced? a cloudy precipitate 11 of 25 When do we stop the stopwatch? when the cross has disappeared 12 of 25 Then repeat this with? different concentrations of sodium thiosulfate 13 of 25 Then repeat whole investigation and calculate? average mean 14 of 25 Not including? anomalous results 15 of 25 What is another word for cloudyness? turbidity 16 of 25 What does this reaction release? sulfur dioxide 17 of 25 This gas is? toxic 18 of 25 Second Method -------------------- Measure out HCl into a? conical flask 19 of 25 Attach a (2)? bung and delivery tube 20 of 25 Then place the delivery tube into a? container filled with water 21 of 25 Place an _______ measuring cylinder? upturned 22 of 25 Also filled with water over the? delivery tube 23 of 25 Add the magnesium and then start? the stopwatch 24 of 25 The hydrogen produced will then be collected? in the measuring cylinder 25 of 25
