Task: How does the concentration of sodium thiosulphate affect the rate of reaction with hydrochloric acid? Aim: Measure the amount of time it takes for different concentrations to sodium thiosulphate to react with hydrochloric acid. Information: * When the two different solutions are mixed together, small solid particles of sulphur are formed in the container. These particles are in suspension; this gives the contents of the container the cloudy, milky yellow appearance. * The higher the concentration of two different solutions the closer together the ions are in the solutions. The closer together they are, the more often the ions collide, greater the chance they have of reacting. * Chemical Equation for Sodium Thiosulphate + Sulphur: * The speed of this reaction is inversely proportional to the time taken for the time taken for the reaction to finish. So the quicker the speed of the reaction the more quickly the sulphur precipitates out. * Liquids have moderate forces...
