A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...
pH meters are electric appliances used for measuring the- alkalinity or acidity of a solution. pH is measured using potentiometric methods or pH indicators such as indicator solutions or strips ...
Understanding the nature of pH has bedeviled beginning (and not-so-beginning) chemistry students for nearly as long as chemistry has had students. It all seems so arbitrary, being the base-10 log of ...
While there are a variety of other variables and protocols to be followed to ensure our food supply remains safe, a basic understanding of pH and how it is measured is crucial to food production.
Using unique nanoparticles that convert laser light into useful information, Rice University scientists have created the world's first nano-sized pH meter. The discovery, which appears online this ...
This method gives a quick, approximate pH reading, making it ideal for home gardeners. Digital pH meters provide a more ...
The color of hydrangea flowers can change from pink to purple and blue by tweaking the soil. How do other plants react to those changes? Sydney Kozak explored just that. Her project, “Does changing ...
