Hanna pH Test Kit (pH 4.0 - 10.0) - HI38058

HI38058 pH Test Kit (pH 4.0 - 10.0) by Hanna Instruments

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.
