Timing a Reaction with the Stop Watch
Start the count at the moment the reagents meet and stop it when the change appears — a cross vanishing under a cloudy solution, a colour change or the last bubble of gas. The display holds the time until reset returns it to zero for the next trial. A student’s reaction at the end point varies far more than the watch’s ± 0.01 sec accuracy, so repeat each run two or three times and average the readings.
