Hanna Instruments HI-38058 pH Test Kit - Range 4.0 - 10.0 pH
The pH value of water can be affected by an array of dissolved substances and is often a good indicator of the quality of the water.
pH Test Kit (pH 4.0 - 10.0)
The HI-38058 pH test kit makes monitoring easy, quick and safe.
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 ionise, 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.
