Get PriceTry a ten-fold or higher dilution of the sample using high-quality deionized water, and repeat the test. If the sample still turns pink initially but then turns clear, try an even higher dilution. If the color appears stable, multiply the result by the dilution factor to get the chlorine concentration of the undiluted sample.
Get PriceFollow the usual test procedure using the diluted sample, and then multiply the result by 2 to find the concentration of the sample before it was diluted. Example: Your sample reads off-scale on your kit or instrument display. Mix 5 mL sample with 5 mL deionized water and repeat the test.

Get Price2021-7-27 · When the pH is above 7.0, the water is alkaline, or basic (there are more hydroxide ions than hydrogen ions). Since the scale is logarithmic, a drop in the pH by 1.0 unit is a 10-fold increase in acidity.
