The HI38058-100 are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate pH measurements with the HI38058 chemical test kit. These reagents follow the colorimetric method to determine pH.
For determination of pH, HI 38058-0 reagent reacts in contact with the aqueous solution changing its color according to the hydrogen-ion concentration (pH) in the given range. The reaction causes a colored complex to form; the greater the concentration, the deeper the color. The Checker Disc supplied with the kit allows for an accurate, side-by-side, visual analysis to determine pH concentration. These reagents are designed to be used with samples that have an expected pH range of 4.0 to 10.
