Commonly called caustic soda, or lye, sodium hydroxide is the most widely used industrial alkali. Depending on the nature of the donor and acceptor atoms which constitute the bond, their geometry, and environment, the energy of a hydrogen bond can vary between 1 and 40 kcal/mol. It dissolves in water because of the charge-dipole interactions between the ions and the water. 16. It is insoluble in water but dissolves in fused NaOH. One property of ionic compounds is that they readily decompose when placed in water, liberating positive ions, known as cations, and negative ions, known as an anions. 7 to be sure that the bond is ionic if not like in your example 1. Like NaCl, the pyrite crystal structure can be thought of as a face-centered cubic array of anions (S 2 2- ) with cations (Fe 2+ ) occupying all the octahedral holes. Due to the opposite charge of the two ions (negative chloride and positive sodium), the two ions are attracted to each other and form an ionic bond. if no - go to 3 3.
