In most coordination polymers, a ligand (atom or group of atoms) will formally donate a lone pair of electrons to a metal cation and form a coordination complex via a Lewis acid/ base relationship (Lewis acids and bases). Coordination polymers are formed when a ligand has the ability to form multipl ...

Heat of Solution for Aqueous Potassium Nitrate
... Water over a range of concentrations from 0m to 0.10m. By interpolation we will then determine IS at 0.05 and 0.1 molals. We will then determine HDS at 0.05m and 0.01m as well as D, 0.05-0.10. Solvation of KNO3 is a strongly endothermic reaction. In fact, this reaction is so endothermic that it ...
