The best improvement could be by prioritizing controlled temperature and standardized mixing would provide a significant improvement over the current method.
The student observes the reaction mixture in a flask on a laboratory bench and records the time it takes for it to turn blue.
The Improvement 1 could be to Control temperature:
Temperature can significantly affect reaction rates. Room temperature can fluctuate, leading to inconsistent results. Perform the experiment in a controlled-temperature environment, such as a water bath or an incubator. This ensures consistent temperature and more accurate time measurements. Improvement 2 is to standardize mixing:
complete question:
A student carried out the experiment using a flask on the laboratory bench. The student recorded the time taken for the reaction mixture to turn blue. State one way this method could be improved, other than by repeating the experiment or by improving the precision of time or volume measurements. Analyze the students methods. What is the best way to improve the experiments
