magnesium bicarbonate
A bicarbonate (Mg(HCO 3 )2) used in
deacidifying papers. The bicarbonate is produced
by passing carbon dioxide through a solution of
magnesium carbonate. The document to be
deacidified is immersed in a bath or sprayed with
a solution of about 10 grams of magnesium
carbonate per liter of water that has been treated
with CO 2 . The advantage of this
method is that it is simple and effective.
