What did you learn from this lab about water and about process?

In this lab I learned may thing about water and about processes. First I learned that there are more than one type of ion precent in a sample of water. For example, in the control, there was a presence of Iron ions and Chloride Ions and also Calcium Ions. I also learned that for the process you have to be very careful, and very thorough. If you mess up one chemical, if you don't clean out the well plates very well you can mix chemicals. So it is very important to be thorough.
