From reading the Forum here, you cannot accurately measure pH beyond 10 ppm of CL, that much i understand.
In one of the Forums, there are several methods to circumnavigate around the problem.
One of them is by diluting the test sample (1:1 ratio) with distilled (only distilled!) water.
Chemistry wise i'm having a problem understand is:
Methods aside, is it better to get the CL, ideally to "0" zero?
shouldn't there be some CL present as it plays a factor in the level of pH?
If triclor and diclor is in the water, shouldnt the pH be lower since it is acidic by nature? Wouldn't that then bring the pH level higher if the CL level in the test sample for forced to go to zero? Using a strong UV light source for instance?
Of cource the opposite would be true if using Cal Hypo or Sodium Hypoclorite - forcing the test sample to go to zero (0ppm CL) by the same method above, wouldn't that make the test sample appear to be acidic ?
if the test sample where to be brought to 0 ( CL = 0 ppm) is that the correct pH level or is it with some level of the type of CL using that should be included in the test sample but lower than 10 ppm? that is my question
Forcing the CL in the test sample to zero i would use a strong UV light source like a black light etc. or i could use and have been using a microwave oven
with the microwave oven, i'll get it hot but not hot enough to make bubbles
