  • Light shield
  • Sodium thiosulfate and hydrochloric acid react in conical flask
  • The transmission of light through the reaction mixture is measured using a datalogger and light sensor
  • As the sulfur precipitate gradually forms, the solution becomes cloudier
  • The amount of light transmitted is a measurement of the reaction's progression
  • Measure and record the time taken for the light intensity to drop to a minimum value
  • Calculate the rate of reaction by calculating 1/reaction time
  • Light source transmits light through reaction mixture
