Any other information on results incl. tables

Plotting the results shows linear behaviour with R2=1 and an equation of:

pH = -0.022 * percentage dPAA + 2.841

From this equation the pH of 100% dPAA is calculated as 0.641

Applicant's summary and conclusion

Conclusions:
The pH of 100% dPAA is calculated as 0.641
Executive summary:

The pH of 100% dPAA is calculated as 0.641
