Who Invented the PH Scale? The potential of Hydrogen, or pH, scale was invented by the Danish biochemist Soren Peter Lauritz Sorensen. He introduced this scale in 1909 to measure the acidity and basicity of substances. The pH scale ranges from 0 to 14. A neutral solution has a pH of 7. It is neither an acid or a base.
During this period, the knowledge of jade craftsmanship spread across the sea to Taiwan and eventually to the Philippines. The artefacts discovered in several sites in the Philippines were made from nephrite. Nephrite excavated in the Philippines were of two types: white nephrite and green nephrite. The Sa Huỳnh culture
first tell me what pH is pH, for those of us who skipped grade school science class and haven't discovered Google, is the level of acidity or alkalinity of a solution.
Litmus paper is the most widely used type of pH paper. Schools generally use it for science and chemistry classes. When a solution is applied to the paper, it will change color to reveal the level of pH found. The indicator litmus is red in acidic solutions (pH less than 7) and blue in alkaline (pH greater than 7) solutions. History

New human species discovered in a cave in the Philippines. A tiny, long-lost cousin of our own human species was discovered, scientists announced.
History books tell us Ferdinand Magellan a Portuguese explorer was the first to discover the Philippines. But all he really did was claim the Philippines for Spain. So who really discovered the Philippines? A long time before Magellan arrived in the Philippines, visitors, traders and colonizers from other lands had come to the Philippines.
Industry laboratories, while intended to advance practical industrial processes, can also be the birthplace of theoretical concepts. Such was the case with the concept of pH, introduced in 1909 by Søren Sørensen as a convenient way of expressing acidity—the negative logarithm of hydrogen ion concentration.
