What is pH

pH, commonly used for water measurements, is a measure of acidity and alkalinity, or the caustic and base present in a given solution. It is generally expressed with a numeric scale ranging from 0-14. The value 7 represents neutrality. The numbers on the scale increase with increasing alkalinity, while the numbers on the scale decrease with increasing acidity. Each unit of change represents a tenfold change in acidity or alkalinity. The pH value is also equal to the negative logarithm of the hydrogen-ion concentration or hydrogen-ion activity. pH values for some common solutions are listed in the table to the right.

Solution pH Value
Battery Acid 0-1
Stomach Acid 2
Coca Cola 2.53
Gatorade (Lemon Lime) 2.93
Black Coffee 5
"Pure" Water 7
Toothpaste 8-9
Household Bleach 12-13

F.A.Q

Use and Care of Electrodes

Electrodes should be rinsed between samples with distilled or deionized water

When adding filling solution, fill up to, but not past the refill hole, when measuring leave the refill hole open for proper flow through the reference junction

Always keep yout pH electode moist by storing it in 4m Kcl Solution pH4 or 7 buffer solution
