Temperature Reaction Rate Experiment - ContentsDa Science Experiment

1. prepare cold, normal, and hot water and measure the temperature of the water with a thermometer 2. prepare 200 ml of chlorinated water for color comparison in a scalpel cylinder 3. add a spoonful of food coloring to the scalpel cylinder 4. add 200 ml each of cold, normal, and hot water. Dissolve the food coloring by stirring with a glass rod 5. The color of the water will change to green as the powder dissolves. 6. Add one chlorine disinfection foam tablet to each of the cold, normal, and hot water and observe the change.

<Result>

The order in which the chlorine disinfection tablets dissolve and disappear

→ Hot water > Normal water > Cold water

Reasons for the rapid disappearance of chlorine disinfection foam tablets in hot water

→ The reaction speed increases as the temperature increases.
