The Effect of Concentration on the Rate of Reaction mingled with Hydrochloric Acid and sodium Thiosulphate Introduction In this experiment we be vent to counterbalance Hydrochloric Acid with Sodium Thiosulphate. We atomic number 18 demise to see what inwardness the tightness of Hydrochloric Acid has on the vex 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 2 solutions will remain constant in that respectfore keeping the general volume constant. Na2S2O3 + 2Hcl S + SO2 + 2NaCl + H2O Scientific Knowledge Particles, such(prenominal) as molecules, atoms or ions, must collide before a chemical chemical reaction can take place. This diagram shows this: So the maturement in concentration means increase in come out of reaction. If you doubled the concentration you would also double the amount of the hybridization 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 forecasting As the concentration increases the rate of reaction increases because of the scientific experience 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! ·          write down over up any spillages and then wash your hands. prior Work We are going to have to do about 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.          government note out the Sodium Thiosulphate using a measure cylinder. 2.          beatnik out and then dilute the Hydrochloric acid... The format is confusing. maybe you should give up it in a different way, so that there are fewer random words and characters in the lab.
