Replacement reagents available
There is no need to buy a new kit when reagents are exhausted. The HN/038058-100 replacement reagents can be ordered for use with this kit.
Significance of Use
pH represents acidity or alkalinity of an aqueous solution and is proportional to the hydrogen-ion concentration of the solution.
Under neutral conditions water is dissociated into the OH- and H+ ions in equal ratio and hence it has a pH of 7. When bases or acids are added to a water solution they ionize, increasing the concentration of OH- or H+, respectively. Thus solutions with a pH of 1-3 contain strong acids, whereas those with a pH of 4-6 contain weak acids.
Weak bases result in solutions of pH 8-10 and strong bases in pH of 11-13. HI38058-0 reagent reacts in contact with the aqueous solution changing its color according to the hydrogen-ion concentration (pH) in the given range.
