The anhydrous salt is practically insoluble in water, acetone, and ammonia. All forms of magnesium carbonate react in acids. At a temperature range between (250°C – 800°C), MgCO3 decomposes to magnesium oxide and carbon dioxide. Magnesium carbonate itself is not toxic. However, its excessive use may cause central nervous system depression and cardiac disturbances. It is slightly hazardous in case of skin and eye contact and may cause respiratory and digestive tract irritation in case of ingestion or inhalation.
