Structures of Simple Ionic Compounds – Every Science

Characteristic structures of ionic solids The simple structures come from the arrangement of the anions (though sometimes the cations) in the positions of the spheres in the fcc or hcp lattices and the cations go into some or all of the octahedral and tetrahedral holes within the lattices Structures based on face centered cubic lattices The Rock Salt structure This the structure adopted by

Applications and functions of food‐grade phosphates

Approximately 20% of muscle food applications include the use of STPP in blends with sodium hexametaphosphate (SHMP also known as sodium polyphosphates glassy) tetrasodium pyrophosphate (TSPP) and/or sodium acid pyrophosphate (SAPP) Common muscle foods in which phosphates have been integral include cured pork products (ham bacon) comminuted meats

Pyrophosphate

A number of pyrophosphate salts exist such as Na 2 H 2 P 2 O 7 Often pyrophosphates are called diphosphates The parent pyrophosphates are derived from partial or complete neutralization of pyrophosphoric acid Important salts include disodium pyrophosphate and tetrasodium pyrophosphate The pyrophosphate bond is also sometimes referred to as a phosphoanhydride

Ionic and Covalent Bonds

Some ionic bonds contain covalent characteristics and some covalent bonds are partially ionic For example most carbon-based compounds are covalently bonded but can also be partially ionic Polarity is a measure of the separation of charge in a compound A compound's polarity is dependent on the symmetry of the compound and on differences in electronegativity between atoms Polarity occurs
