What is the phenomenon of magnesium carbonate dissolving in water

              The dissolution process of magnesium carbonate in water is relatively smooth because its solubility is very low,about 0.02%(at 15℃).Due to its low solubility,it will not completely dissociate into ions in water,so there will be no color change or obvious exothermic or endothermic phenomena.The dissolution reaction of magnesium carbonate in water can be expressed as:

              MgCO3+H2O↔Mg2++CO32-+H2O

              In addition,the solubility of magnesium carbonate in water will slightly increase with increasing temperature,but overall,this change is not significant.It should be noted that if water contains a large amount of carbon dioxide,magnesium carbonate can react with carbon dioxide and water to form water-soluble magnesium bicarbonate.

              In summary,when send us a message now. is dissolved in water,due to its extremely low solubility,there will be no obvious physical phenomena.
