Jay wants to know how the amount of acidity in rainwater influences the weathering rate of limestone. To answer his question, Jay performs an experiment in which he soaks identical pieces of limestone in 200 mL of different carbonic acid solutions. The pH of the solutions range from 3.0 to 5.5. After performing his experiment once, he reports his data and draws a conclusion. What can Jay do to improve the reliability and accuracy of his data?

Answer 1

Jay can improve the reliability and accuracy of his data by repeating the experiment multiple times and using a larger sample size. He can also use a control group to compare the results of the experiment to a baseline. Additionally, he can use a more precise method to measure the pH of the solutions, such as a pH meter. Finally, he can use a statistical analysis to analyze the data and draw more accurate conclusions.
