UD's long-term monitoring shows 60 percent reduction in acidity of Delaware rain Several decades ago, precipitation in Delaware was among the most acidic in the country. Pollutants in the air reacted with rainwater to sprinkle sulfuric, nitric and carbonic acids onto the ground below, affecting crops and ecosystems statewide. The scientific consensus is that pollution controls enacted through the Clean Air Act Amendments in the 1990s and other measures have helped decrease the acidity...

Researchers from New York University and the Max Planck Institute in Stuttgart reveal how protons move in phosphoric acid in a Nature Chemistry study that sheds new light on the workings of a promising fuel cell electrolyte. Phosphoric acid fuel cells were the first modern fuel cell types to be used commercially and have found application as both stationary and automotive power sources. Their high efficiency as combined power and heat generators make them attractive targets for further...

Modern methods for mass production of biological agents and fine chemicals require precise control of pH. However within these systems it is not always possible to use traditional methods for measuring acidity and alkalinity. Biomed Central's open access journal BMC Biotechnology describes a new and user friendly method for measuring pH, which uses luminescent dual life-time referencing (DLR), to provide real-time characteristics of enzyme reactions. Industrial methods for manufacturing...

Riding the wind and ocean currents, hordes of blue, alien-like creatures descend upon Southern state coastal waters, entangling beach goers in poisonous tentacles and delivering painful stings by the hundreds. Houston, Texas (PRWEB) March 26, 2012 Each invader, in fact, isn't an "it" but a "they" – a colony of organisms that combine to create a single entity; the Portuguese man-of-war. The seafaring wanderer with the neon-blue gas bag and tentacles as long as 30 feet seems more suited...

Sometimes, solutions for hard problems can turn out to be pretty basic. That's especially true for a team of researchers at the Office of Science's Brookhaven National Laboratory (Brookhaven Lab), where the solution for a hard problem they were working on turned out to be pretty basic . . . and also a bit acidic. The hard problem they were working on was how to store hydrogen fuel. Hydrogen gas (H2) is a clean and powerful fuel, but it's also extremely light, which makes it difficult and...

By studying samples from carbon-rich meteorites, scientists with NASA's Goddard Space Flight Center say they have discovered that the building blocks of life can be created and maintained in extreme heat, not just in cooler conditions as had previously been believed. In a Friday press release, the U.S. space agency reports that experts from the Greenbelt, Maryland facility's Astrobiology Analytical Laboratory studied 14 samples and discovered "minerals that indicated they had experienced...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...

  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
