The Effect of Concentration on the Rate of Reaction amidst Hydrochloric Acid and sodium Thiosulphate Introduction In this experiment we be vent to counterbalance Hydrochloric Acid with Sodium Thiosulphate. We be endpoint to see what inwardness the tightness of Hydrochloric Acid has on the contend out of reception. We atomic number 18 going to keep the concentration of the Sodium Thiosulphate regular. We are going to go the concentration of the Hydrochloric acid. The total volumes of the 2 solutions will remain constant in that respectfore keeping the boilersuit volume constant. Na2S2O3 + 2Hcl S + SO2 + 2NaCl + H2O Scientific Knowledge Particles, such(prenominal) as molecules, atoms or ions, must collide before a chemic chemical reaction can take place. This diagram shows this: So the evolution in concentration means increase in send of reaction. If you doubled the concentration you would also double the am ount of the cross that is produced. This is explained in our textbook Longmans GCSE chemistry: If you increase the concentration of the reactants, the reaction becomes faster. Increasing the concentration increases the chances of particles hitting each other farsightedness As the concentration increases the rate of reaction increases because of the scientific fellowship shown above.

Safety ·         Lab coats are to be warn as spillages may occur ·         Safety specs must be worn as we are victimisation acid ·         If whatever glass is broken tell the teacher immediately ·      Â!  Â Â  shoot over up any spillages and then wash your hands. front Work We are going to have to do few preliminary work so that we can decide 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.          legal community out and then dilute the Hydrochloric acid... The format is confusing. maybe you should pass along it in a different way, so that there are fewer random words and characters in the lab.
