The Disappearing Cross Experiment is a classic chemistry practical used to study the rate of reaction between sodium thiosulfate and hydrochloric acid. In this experiment, the reaction produces sulfur, which makes the solution cloudy. By measuring the time taken for a cross mark below the flask to disappear, students can calculate and compare reaction rates. The reaction equation is: Sodium thiosulfate + Hydrochloric acid → Sodium chloride + Sulfur dioxide + Sulfur + Water.
