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?

- To check the reliability of our experiments we repeat the experiment many times and see if we get the same results or almost same results.

It's also good to compare the results of two or more students for the same experiment and see if they get the similar results.

So, to improve the reliability and accuracy of the experimental data, Jay needs to repeat the experiment and also ask his one or more friends to do the experiment and record the data.

is there multiple choice answers?

the answer would be a
