The pH scale that is widely accepted and used by scientists didn't actually exist until 1909. Before then scientists had to rely on using adjectives to describe the acidity or basicity of a substance ...

The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.

There’s a time for tongue-puckering lambics and Berliner Weisses, but most beer drinkers want something a little more balanced for day-to-day sipping. Thanks to the pH scale that Tuesday’s Google ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American I remember learning about acids and bases (or ...

The Danish scientist's revolutionary test of acidity and alkalinity is still used today THE distinguished chemist is little known outside of his native Denmark. Here’s what we know about the enigmatic ...

pH is the measure of hydrogen ions in water-based liquids. The pH scale shows the leaves of acidity and alkalinity of water and similar liquids. There are some important things to understand about the ...

The pH scale is used to measure acidity and alkalinity levels. It measures the presence of positively and negatively charged hydrogen ions in a particular solution. The higher the hydrogen ions, the ...

Most teas are mildly acidic. Acidity is determined by the pH scale. Neutral is around 7 and anything under a pH of 4 is considered very acidic. Some tests show that certain teas may be as low as 3. If ...

For several decades antimony electrodes have been used to measure the acidity/basicity -- and so to determine the pH value. Unfortunately, they allow for measuring pH changes of solutions only at a ...
