I am studying and going over the chlorine testing. I had brain problem last year and can’t remember how I tested chlorine. The other tests seem ok and
I dont have trouble doing them, but the chlorine just skips me, I can’t remember it. The instructions don’t help. With the 0.2 and 25 ml of water
I add the R 0870, when the water is pink I add R 0871, keep adding until its colorless. Now if I have 26 drippings to make it colorless, it means I have
5.2 ppm of chlorine? is the correct? I am using the k-2006c.

PS - You have the math correct. Good job! To make the math easier, you can use a 10 ml test sample and multiply the drops used by .5. I like that math better.

I'm with bmoreswim. Use the 10 ml sample and only one scoop of powder. And forget multiplying by .5. Just cut the drops in half. 10drops =5 FC. 7drops? 3½. Real simple, real fast, saves on reagents.
