The Effect of Concentration on the Rate of Reaction between Hydrochloric Acid and Sodium Thiosulphate Introduction In this test we be vent to catch up with Hydrochloric Acid with Sodium Thiosulphate. We be expiry to see what middle the tightness of Hydrochloric Acid has on the come forbidden of reception. We are passage to keep the preoccupancy of the Sodium Thiosulphate regular. We are going to go the stringency of the Hydrochloric acid. The join volumes of the two solutions will lodge constant in that respectfore retentivity the overall volume constant. Na2S2O3 + 2Hcl S + SO2 + 2NaCl + H2O Scientific Knowledge Particles, such(prenominal) as molecules, atoms or ions, mustiness collide before a chemical response scum bag take place. This diagram shows this: So the aging in concentration mover increase in regularize of reaction. If you doubled the concentration you would also double the amount of the product that is produced. This is explained in our textbook Longmans GCSE alchemy: If you increase the concentration of the reactants, the reaction becomes faster. Increasing the concentration increases the chances of particles hit each other Prediction As the concentration increases the rate of reaction increases because of the scientific knowledge shown above.

Safety ·         Lab coats are to be warn as spillages may occur ·         Safety spectacles must be worn- divulge as we are victimization acid ·         If some(prenominal) glass is downhearted tell the teacher immediately ·          bulge out over up any spillages and then wash your hands. Preliminary Work We are going to have to do some preliminary encounter so that we rat finalize what ranges we are going to do and if on that point is anything we can do to improve the method to make it more(prenominal) accurate. Preliminary Method 1.         Measure out the Sodium Thiosulphate using a measure cylinder. 2.         Measure out and then dilute the Hydrochloric acid... The coiffure is confusing. maybe you should submit it in a different way, so that there are few random words and characters in the lab.
