HI 3886/0 pH Test Kit 7.5 – 10.0 pH Product Description: 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 ... Read More »
