Carbonate Ion → Magnesium bicarbonate

Participants

Reaction Steps

When the water-containing fibrous basic magnesium sulfate particles are dried in a drying oven, the CO2 gas present in the oven is dissolved in the water portion of the water-containing fibrous basic magnesium sulfate particles to produce carbonate ions. Further, the water portion in which CO2 gas is dissolved turns acidic. In the acidic water portion, Mg ions are released from the fibrous basic magnesium sulfate particles. The carbonate ion and Mg ion in the water portion are considered to form together magnesium hydrogen carbonate [Mg(HCO3)2], which is deposited in the form of a carbonate such as magnesium carbonate or basic magnesium carbonate.
