pH paper / solution vs. bleach
I want to measure the pH of a solution containing chlorine and hypochlorite ions.
However, my pH-paper is turning useless after a drop of this bleaching solution, it just keeps the yellow colour it had and gradually fades to a
white-ish yellow.
An indicator solution was even worse, the color faded the second it went into the solution.
Now, I don't have a pH-meter, but I wouldn't feel comfortable sticking it in that aggressive solution anyway.
Is there some trick to measure the pH regardless?
we apologize for the inconvenience
