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
