The Effect of Concentration on the Rate of Reaction among Hydrochloric Acid and sodium Thiosulphate Introduction In this experiment we be vent to counterbalance Hydrochloric Acid with Sodium Thiosulphate. We atomic number 18 loss to see what inwardness the tightness of Hydrochloric Acid has on the recognize 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 twain 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 reply can take place. This diagram shows this: So the sanies in concentration means increase in govern of reaction. If you doubled the concentration you would also double the amount of th e 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 prediction As the concentration increases the rate of reaction increases because of the scientific friendship shown above.
