#175661 pH adjustment of 3.5% NaCl solution

Posted by Fiaq Khan on 02 July 2015 - 03:45 AM in General Lab Techniques

I have made a 3.5% NaCl solution using distilled water. I am trying to raise the pH of this NaCl solution from its actual pH 6.8 to 7.8 using 0.1 M NaOH solution. The problem I am facing is that once the pH value reached ~7.8 then after one day it drops back to its original pH of 6.8. I have also tried to adjust the pH using 1 M Na2HPO4 buffer solution having  pH ~9.0. But the problem remain same. In this case after one day the pH drops down to 7.5.

Can you give some suggestions about how can I increase the pH value of this solution to 7.8 so that it remains fix and does not change. Looking forward for your help. Thanks a lot.
