How much does liquid 6% Chlorine change PH

[mas985]

Bleach has a PH of about 12 but you are only adding 1 gallon to 10000 so you would not expect much of a change. If you are so inclinded, you can use this formula:

-log10(10^(-7.4)+(10^(-12))/10000) = 7.3999999989

Hm. I would expect the pH to go up, not down. You sure that formula is correct?

Sorry, I made an approximation. The proper solution is:

-log10(10^(-7.4)*10000/10001+10^(-12)*1/10001) = 7.4000434261859642546351588394264

And this equation is really only good for solutions without buffers so it is not that accurate for a swimming pool but I do believe it is a worst case.

Cool that makes sense now. Bottom line is that it's an tiny tiny change.

Thank you for this final answer.

Now I know that life will be a never-ending fight between iron and ph.

Does anyone know where I can get a tanker of muriatic cheap? And I thought gas was expensive.

Hello, I am such a newbie here I am embarrassed to write. But I have been reading Ben's Site and Forums from top to bottom for the past year. And when I saw your post I thought you might be interested in the section Ben has titled "Benefits of High pH Swimming Pools". You can find in on the main home page right under the section about "Avoiding summer ear infections".
Well there. There is my first post. I have been reading all of you verteran's posts, I feel like I have know you for years.
Enjoy your pool!
