Overview
The Hach acidity reagent set is designed to determine acidity by Digital Titrator titration, with Methyl Orange (using bromphenol blue indicator) and Phenopthalein endpoints. Bromphenol blue (pH 3.7) or phenolphthalein (pH 8.3) indicator is used to titrate the sample with sodium hydroxide to a colorimetric endpoint. Bromphenol blue gives a better endpoint than the methyl orange indicator. Titration to pH 3.7 determines strong mineral acidity (also referred to as methyl orange acidity), whereas the pH 8.3 phenolphthalein endpoint includes weaker acid species and represents the total acidity. The results are expressed in mg/L as calcium carbonate (CaCO3) at a specified pH.

Ocean acidification: University of Washington's giant plastic bags help control research conditions
With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

NOAA Alaska buoy network to monitor North Pacific ocean acidification
National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action. “We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks. To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.

Angler-Driven Citizen Science: Monitoring Black Bass Populations in Arkansas
In Arkansas, the rugged terrain of the Ozark and Ouachita Mountains dominates the north and west, eventually yielding to the vast, fertile flatlands of the Mississippi River Delta to the east. Hundreds of reservoirs and lakes punctuate the landscape, while swift streams snake through the valleys and hills, eventually giving way to the slow-moving rivers and bayous in the south. The waterways of the state are teeming with life. Black bass dominate most of these ecosystems and have drawn anglers for centuries. The most sought-after fish in one of the country's most prominent fishing states, Arkansas treasures its black bass populations.
