Magnesium nitrate

Description

Clear, deliquescent crystals that occur naturally as the mineral nitromagnesite. In a closed environment, a saturated aqueous solution of magnesium nitrate will form an equilibrium at a relative humidity level of about 55% (20C). Magnesium nitrate is also used in fireworks.
