Preparation
O-calcium periodate can be prepared by the reaction of periodic
acid and calcium hydroxide:
Ca(OH)2 ＋2HIO4→Ca(HIO4)2＋H2O
The meta-salt is
formed when the acid is in excess and the ortho-salt
when the hydroxide is in excess. However, a detailed
study of these conditions upon the product produced
has not been available.
