The following data were obtained when a Ca2+ ion-selective electrode was immersed standard solutions whose ionic strength was constant at 2.0 M.
Acid Rock Drainage is a common environmental process that releases toxic metals, such as cadmium (Cd2+), and lots of acidity (i.e. H+) into streams and rivers. One strategy to remediate acid mine drainage is to fill the streams with carbonate rock..
