600 Lab activity:  Students will serially dilute an NaOH solution and determine the pH of each dilution with a Vernier probe.  They will download the data to a computer and prepare a graph
600 Students will jutify the difference between the measured and calculated pH values
600 Students will use their graphs to predict the pH of solutions with molarities different from those prepared in the lab
600 Students will calculate the standard deviation and mean values of the pH for each dilution
600 Students will graph the mean values and determine if this graph is more accurate than their individual graphs
600 Experience solving dilution problems involved in agriculture
