Rate of reaction Investigate the affect of changing the concentration of Sodium Thiosulphate, on the reaction between Hydrochloric Acid and Sodium Thiosulphate. Variables 1. The concentration of Sodium Thiosulphate 2. The concentration of Hydrochloric Acid 3. Temperature of both solutions 4. Volume of Sodium Thiosulphate 5. Volume of Hydrochloric Acid 6. The depth of each solution in the conical flask 7. The intensity and duration of mixing of the solution The investigation will determine how the concentration of Sodium Thiosulphate will affect the reaction between Hydrochloric Acid and Sodium Thiosulphate. What to change The concentration of Sodium Thiosulphate will be changed during the investigation. What to measure The time taken for a certain amount of precipitate to be produced to obscure a pencilled 'x' will be measured. (The pencilled 'X' will be on a white piece of paper on which the conical flask will stand.) What to keep the same 1. The concentration of Hydrochloric Acid 2. Temperature of both solutions 3. Volume of Sodium Thiosulphate 4. Volume of...
