Level Testing Maintaining and controlling proper pH levels is essential
to many agricultural, industrial and environmental processes. In agriculture,
proper pH of the soil ensures good crop growth. For drinking water, processing
plants have to control pH in order to produce safe drinking water. Environmentally,
pH monitoring and control are critical to prevent damage or deterioration of the
quality of all plant, animal and human life. pH
Level Testing pH is a numeric scale used to express a solution’s acidity
or alkalinity. Acidity or alkalinity refer to a solution’s concentration of hydrogen
ions. The greater the concentration of hydrogen ions, the more acidic the solution.
The fewer hydrogen ions and a solution is considered alkaline.The pH scale ranges
from 0 to 14. Seven is the midpoint at which a solution (such as distilled water)
is neither acid oralkaline. A pH lower than seven indicates more acidic solutions
like vinegar (3.0 pH), sulfuric acid (1.2 pH) or orange juice (3.7 pH). pH values
higher than 7 represent alkaline or basic solutions such as sodium hydroxide (pH
13), ammonia base household cleaners (pH 12), and potassium hydroxide (pH 14).
Ways to Measure
pH The first step in controlling pH is measuring it. pH can be measured
by various methods including pH paper, digital readout pocket testers, portable
and bench top meters. pH paper is an inexpensive and quick way to check pH. Strips
of paper are impregnated with a chemical indicator. This indicator, when immersed
in a sample liquid, turns the paper test strip a specific color. The pH of the
sample liquid is determined by visually comparing the color of the test strip
to a standard chart. Pocket
and Bench pH Testers An alternative to pH paper is the pocket tester.
Convenient and easy to carry, these testers are ideal for field use. pH tests
can be made quickly without having to take a sample back to the laboratory. Pocket
testers provide enough accuracy for general applications and are relatively inexpensive.
When more accuracy is required, portable meters are a good choice. Most portable
meters are larger in size than pocket pH testers. They use a wide variety of replaceable
pH electrodes for individual applications and conditions. Bench top meters are
found mainly in testing or research laboratories. They are generally more expensive
but offer increased accuracy and more testing options.
