Re: what are the IV and DV and how will the data table look
An independent variable is one that you control. In this experiment it might be the length of time you have run the current through the solutions: call it "t".
A dependent variable is one that depends on the independent variable. For example, what is the pH after a time, t? The pH depends on t.
A table of your results will have at least two columns. One is t and the other is pH.
