Overview
The Hach Hardness (Calcium) reagent set is designed to determine Calcium Hardness by EDTA Digital Titrator Titration Method. The sample is made alkaline (pH 12-13) with potassium hydroxide to precipitate magnesium as magnesium hydroxide. CalVer 2 Indicator is added and combines with any calcium to form a pink-red color. As EDTA is added, it reacts with the free calcium ions present. When no free calcium ions remain, the EDTA then removes the calcium complexed with the indicator, causing a color change to blue.

  • Range: 10-160 mg/L as CaCO3
  • (100) CalVer 2 indicator powder pillows
  • (1) 100 mL potassium hydroxide standard solution, 8.00 N
  • (1) EDTA titration cartridge, 0.0800 M

Save our Bogs! Culture, Conservation and Climate Action in Ireland’s Peatlands

Characterized by long-term accumulation under waterlogged conditions, peatlands exist on every continent and account for 3-4% of the global land surface . Small but mighty, these often overlooked wetland environments are estimated to hold as much as one-third of the world's organic carbon in their soil—twice the amount found in the entirety of the Earth's forest biomass. While healthy peatlands can trap and store carbon, regulate water, and provide important habitats for rare species, human alteration has disturbed peatland carbon and nitrogen cycles on a global scale. Approximately 12% of the world’s peatlands have been drained and degraded through conversion for agriculture, forestry, infrastructure development, and other uses.

Sargassum Surge: How Seaweed is Transforming our Oceans and Coastal Ecosystems

Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.

Great Lakes Research Center: Designing Targeted Monitoring Solutions

According to the National Oceanic and Atmospheric Administration ( NOAA ), the Great Lakes have more miles of coastline than the contiguous Atlantic and Pacific coasts combined and contain 20 percent of the world's freshwater, making it a critical region to protect and conserve. Continuous monitoring and data-informed resource management are key components of managing waters in the region. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs and deploys monitoring platforms throughout the Great Lakes. With a background in environmental engineering, Henderson enjoyed the challenge of creating systems and making them work to obtain difficult, remote measurements.
