Investigation of Sodium Thiosulphate and Hydrochloric Acid - The purpose of this investigation is to record the amount of time taken for a reaction to occur when sodium thiosulphate is mixed with hydrochloric acid. The equation for this reaction is: Na2S2O3 + 2HCl → 2NaCl + S + SO2 +H2O Sodium thiosulphate (Na2S2O3), after reacting with Hydrochloric Acid (HCl) produces yellow sulphur, which is the cause of the solution becoming cloudy. The amount of time taken for the reaction to occur is known as the reaction rate. The rate of a reaction can be commonly explained by Collision Theory....   [tags: Chemistry, observation] 641 words

The Rate Of Reaction Between Magnesium And Hydrochloric Acid - The Rate Of Reaction Between Magnesium And Hydrochloric Acid Aim My aim is to see how the rate of reaction between magnesium and hydrochloric acid is affected by changing the length of magnesium. Hypothesis I predict that if the length of magnesium is high then rate of reaction will be much more longer because if the length of magnesium is more then it will take longer to dissolve and therefore it will react for a longer time.
