Introduction

AIM I aim to investigate how changing the concentration of sodium thiosulphate affects the rate of the reaction with hydrochloric acid. The reaction The reaction that will occur is a cross-drawn on a piece of paper disappearing because a precipitate (very fine solid) ...read more.

    By varying the amount of water in the 20 ml of Sodium Thiosulphate solution, I will vary the concentration. I will first put the hydrochloric acid in a beaker with a cross on a piece of paper underneath.

  2. An Experiment to Investigate the Effect of Changing the Concentration of Hydrochloric Acid on ...

    In the preliminary experiment I had to keep changing the piece of paper the cross was on because water and acid and the thiosulphate sometimes spilt on it and faded the cross making it lighter and lighter and therefore the rate of reaction in some places increased when actually it was meant to decrease.

    Observation of reaction What happens to the chalk? What is the rate of reaction between chalk and hydrochloric acid? Chalk Exothermic A lot bubbles come out It dissolves 4 If the chalk dissolves then it is not re-usable after the reaction.

  2. To investigate how changing the temperature affects the rate of reaction between sodium thiosulphate ...

    There would be more collisions, as the solution would be stronger. Apparatus: * Thermometer * Beaker * Measuring cylinders * Conical flask * Tripod * Gauze * Heatproof mat * Stopwatch * Bunsen burner * Pair of tongs * Pair of goggles Diagram: Prediction: I predict that as the temperature increases so will the speed of reaction.

  1. To investigate a factor that affects the rate of reaction and why?

    1.5, 2M The first concentration I am going to do is 0.2M of HCl. However, because I only have 2M acid I must make up the weaker concentrations myself. To make 0.2M I will measure 1cm3 of HCl into the measuring cylinder and make up the rest with 9cm3 with distilled water.

  2. How changing the concentration of acid affects the rate of reaction

    I will be changing the amount of concentration of acid used, 5 times. My final variable is dependent, this is the main thing you are measuring, and in my case I will be measuring the time solution takes to react.
