I tried a fast pH test on the Oxone. Measured 2.0 g of Oxone, dissolved in 200 ml H2O, purified water ( de-ionized, reverse osmosis ) bought at local grocery store.
Well, I expected to see a low pH, since this would correspond to a 1 % percent solution, right ? According to the DuPont MSDS, the pH should be around 2.0.
I measured the water pH first , to be sure, used my electronic pH meter which I trust, never had problems with before.
Well, water pH = 7.3 - 7.4
After adding the Oxone ( tried it twice, washed everything just to be sure )
With Oxone added, ph = 9.5 once, 9.8 second try.
Is it right ? Is the Oxone old ( possible ) or has it some other stuff added ? Why is the pH basic ?
