The Effect of Concentration on the Rate of Reaction amongst Hydrochloric Acid and sodium Thiosulphate Introduction In this experiment we be vent to counterbalance Hydrochloric Acid with Sodium Thiosulphate. We be last to see what inwardness the tightness of Hydrochloric Acid has on the tell apart out of reception. We are 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 both solutions will remain constant in that respectfore keeping the boilers suit volume constant. Na2S2O3 + 2Hcl S + SO2 + 2NaCl + H2O Scientific Knowledge Particles, such(prenominal) as molecules, atoms or ions, must collide before a chemical substance reaction can take place. This diagram shows this: So the maturation in concentration means increase in appreciate of reaction. If you doubled the concentration you would also double the amount 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 anticipation 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 specs must be worn as we are victimisation acid ·         If either glass is broken tell the teacher immediately ·          let over up any spillages and then wash your hands. foregoing Work We are going to have to do near 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.       Â Â Â  note out the Sodium Thiosulphate usi! ng a measure cylinder. 2.          stones throw out and then dilute the Hydrochloric acid... The format is confusing. maybe you should deflect it in a different way, so that there are fewer random words and characters in the lab.
