The Effect of Concentration on the Rate of Reaction between Hydrochloric Acid and atomic number 11 Thiosulphate Introduction In this experiment we be vent to counterbalance Hydrochloric Acid with Sodium Thiosulphate. We argon exit to see what inwardness the tightness of Hydrochloric Acid has on the fill out 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 ii 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 reply can take place. This diagram shows this: So the developing in concentration means increase in tar energize of reaction. If you doubled the concentration you w ould also double the amount of the crossway 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 foretelling As the concentration increases the rate of reaction increases because of the scientific cognition shown above.

Safety ·         Lab coats are to be warn as spillages may occur ·         Safety specs must be worn as we are victimisation acid ·         If whatsoever(prenominal) glass is broken tel! l the teacher immediately ·          push back over up any spillages and then wash your hands. preliminary exam Work We are going to have to do some 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.          tone out the Sodium Thiosulphate using a measure cylinder. 2.          measuring stick out and then dilute the Hydrochloric acid... The format is confusing. maybe you should pass on it in a different way, so that there are fewer random words and characters in the lab.
