Alunite Crystal Chemistry

Alunite has been described both by the chemical formula KAl3SO42OH6 and by the chemical formula K2SO4·Al2SO43·2Al2O3·6H2O The latter gives an erroneous impression that water is structurally associated with the mineral The former representation is therefore to be preferred It is more in conformity with the crystal structure of alunite
