description Product Description
Used in analytical chemistry as a primary standard for iron titrations, particularly in redox titrations like permanganometry and cerimetry. Serves as a source of iron in educational laboratory experiments due to its stability and well-defined composition. Employed in the preparation of iron-containing calibration standards for spectroscopic analysis. Also used in wastewater treatment as a coagulant aid in combination with other chemicals to remove phosphates and suspended solids. Found in some photographic processes and as a mordant in textile dyeing to improve color fastness.
