Latest Acid-base chemistry Stories
MAGNA -- Hazardous materials crews from the Unified Fire Authority along with officials from the Utah Department of Transportation and Salt Lake Valley Health Department are trying to figure out how a batch of sulfuric acid ended up on the side of a state road Friday.
By Jessen, Andrea Randall, Andrew; Reinhart, Debra; Daly, Luke ABSTRACT: This study examined whether ferrate could meet the international standards for successful ballast water treatment, including final concentrations of less than 1 CFU/mL of Enterococci, less than 2.5 CFU/mL of Escherichia coli, and less than 1 CFU/100 mL of Vibrio cholerae.
By Jangbarwala, Juzer A recendy completed plant in the Power River basin in Wyoming uses a new method for treating water produced from coalbed methane (CBM) wells. The new fixed-bed dynamic flow ion exchange system provides better cost efficiency and less waste byproduct than other processes.
By Niki Sullivan, The News Tribune, Tacoma, Wash. Jul. 29--A faulty batch of chemicals might have caused the pH level of Wapato Lake to plummet during an algae treatment Friday, suffocating large numbers of fish, according to the company hired to monitor water quality.
By Matthew D. LaPlante, The Salt Lake Tribune Jul. 3--For years, the military has insisted that there is no safer way to destroy its chemical weapons than the incineration process used at the Deseret Chemical Depot.
U.S. environmental scientists say they have created one of the most comprehensive databases on the effects of acid rainfall. Prior to enactment of the U.S.
By Ward, Weslyn C Lamb, Erin C; Gooden, David; Chen, Xin; Burinsky, David J; Simon, John D ABSTRACT Three naturally occurring pyrrole acids were found in Sepia, human black hair, and bovine choroid and iris melanosomes using high-performance liquid chromatography and mass spectrometry- pyrrole-2,3-dicarboxylic acid (PDCA), pyrrole-2,3,5-tricarboxylic acid (PTCA) and pyrrole-2,3,4,5-tetracarboxylic acid (PTeCA).

By Loi, G; Rossi, A; Trois, P; Rossi, G Abstract Until recently, two types of bioreactors were used for bioleaching: the stirred tank reactor (STR), borrowed from chemical engineering, and the so-called Pachuca tank airlift reactor (ALR), borrowed from hydrometallurgy.
Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
A pH meter, typically consisting of a special measuring probe connected to an electronic meter, is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. The probe measures pH as the hydrogen ion activity that surrounds a thin-walled glass bulb at its tip. A small voltage is produce by the probe that measures and displays pH units by the meter. The meter circuit displays voltmeter in pH units instead of volts. The circuit of the pH meter consists of operational...
