How is pH found?
Measuring pH. pH can be measured three ways: the electrode method, the colorimetric method and the hydrion paper method. The electrode, the most common and probably the most accurate, uses a probe and meter. The meter measures the slight voltage differences between a reference electrode and a measuring electrode.
Where does pH come from?
The term “pH” was first described by Danish biochemist Søren Peter Lauritz Sørensen in 1909. pH is an abbreviation for “power of hydrogen” where “p” is short for the German word for power, potenz and H is the element symbol for hydrogen.
Where is pH used?
pH Measurement is used in a wide variety of applications: agriculture, wastewater treatment, industrial processes, environmental monitoring, and research and development. pH is a measure of the Acidity or Alkalinity of a Solution. The pH value states the relative quantity of hydrogen ions (H+) contained in a solution.
When was pH found?
1909
In 1909 Sørensen, a Danish chemist, introduced the concept of pH as a convenient way of expressing acidity.

Is PH short for Philippines?
The codes assigned to the Philippines are PH and PHL. To avoid confusion and ambiguity, offices of the Philippine Government will use the initials PH and PHL when referring to the Philippines.
What foods have low pH?
Foods and drinks with a low pH include lemons, other fruit and fruit juices, soft drinks, pickles, and fermented products such as yogurt.
Why is a high pH bad in your body?
When the blood pH level (the measurement of acidity or alkalinity in the blood) goes too high or too low, it causes significant health problems in the body. A high pH level is called “alkaline” or “basic.”. If our blood pH level is too high, it can lead to muscle twitching, nausea, confusion, coma and other negative health effects.
What is the formula for calculating pH?
The formula for pH is pH = -log[H+]. This means pH is the negative base 10 logarithm (“log” on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer.
What causes a high pH level?
A pH imbalance in people that skews a blood pH above normal levels is called alkalosis. A high pH can occur in the body for a few reasons, including abnormal kidney/liver function, digestive problems, medication effects and problems with the lungs. Respiratory alkalosis results when the levels of carbon dioxide (an acid) are too low in the body.
