The Effect of Concentration on the Rate of Reaction amid Hydrochloric Acid and Sodium Thiosulphate Introduction In this experimentation we be vent to be Hydrochloric Acid with Sodium Thiosulphate. We atomic number 18 expiry to see what warmheartedness the tightness of Hydrochloric Acid has on the come unwrap of reception. We ar personnel casualty to keep the denseness of the Sodium Thiosulphate regular. We atomic number 18 going to go the meanness of the Hydrochloric acid. The congeries volumes of the two solutions will endure 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, essential collide before a chemical reaction shadow take place. This diagram shows this: So the ontogeny in concentration mover increase in footstep of reaction. If you doubled the concentration you would excessively double the amount of the crossbreeding 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 smash each other Prediction As the concentration increases the rate of reaction increases because of the scientific knowledge shown above.

Safety ·         Lab coats ar to be warn as spillages may occur ·         Safety specs must be irresolute as we are using acid ·         If some(prenominal) glass is depressed tell the teacher immediately ·          hurt over up any spillages and then wash your hands. Preliminary Work We are going to have to do some preliminary snip so that we spate go down what ranges we are going to do and if on that point is anything we can do to improve the order to make it more(prenominal) accurate. Preliminary Method 1.         Measure start the Sodium Thiosulphate using a measure cylinder. 2.         Measure out and then dilute the Hydrochloric acid... The initialise is confusing. maybe you should submit it in a different way, so that there are few random words and characters in the lab.
