If you did not collect any data or are missing some data to complete this post-lab, then give your source of data here and give a brief explanation why you have missing data. If you use your own data you can go straight to question 1, no need to add anything here. Calcium chloride was added to the water in the "testing" experiments to simulate hard water. What was the effect of adding the calcium ions to the ability of...
