Lesson details
Lesson outcome
I can carry out a fair test to investigate how the rate of reaction depends on the concentration of a reacting solution.
Show transcript
The reaction between sodium thiosulfate solution and hydrochloric acid produces a cloudy precipitate.
At the end point of the disappearing cross experiment, each reaction has produced the same amount of product.
At the end point of the disappearing cross experiment, the chemical reaction may not be complete.
Increasing concentration of a reacting solution introduces more reactant particles, so they collide more frequently.
