Conference: International Symposium on Metal Complexes (ISMEC 2018) will be held in Florence, Italy, from 3rd to 7th June 2018

Freeware
	GLEE: Determination of standard electrode potential by a Gran method
	VLpH: Calibration of glass electrode for use at very low pH
	Definitions and explanations (pdf document)
	Carbonate impurity (pdf document) The effects of a cabonate impurity on titration curves
	Soleq tutorials from Academic Software. These tutorials are prepared for use by middle and advanced level university undergraduates. They are intended for use either in individual study or in class teaching. They cover the principles of equilibrium in solution chemistry: acid-base reactions, oxidation and reduction, solubility and metal-ligand chemistry.,There are tutorials on both homogeneous and heterogeneous systems. Each topic area includes examples relating to real systems: in biology, in soils and in natural waters.
