Calcium carbonate is a basic substance, so its pH level is typically around 9-10 when dissolved in water.
Magnesium carbonate and calcium carbonate are both white powders, but they have different properties and uses. Magnesium carbonate is less dense and more soluble in water than calcium carbonate. It is commonly used in antacids and as a drying agent in some products. Calcium carbonate is more commonly used as a dietary supplement and in the production of cement, paper, and plastics.
Calcium carbonate is generally a stronger acid than magnesium carbonate. This is because calcium is positioned higher in Group 2 of the periodic table than magnesium, meaning calcium has a greater tendency to lose its outer electrons and behave as an acid.
The solubility of calcium carbonate decreases as pH increases. This is because calcium carbonate is more soluble in acidic conditions and less soluble in basic conditions.
To reduce acidity in soil, you can add agricultural lime (calcium carbonate) or dolomitic lime (a mix of calcium carbonate and magnesium carbonate). These products help neutralize soil pH by raising the levels of calcium and magnesium while decreasing acidity. It's important to conduct a soil test first to determine the exact amount needed for effective results.
It raises the pH of the soil and reduces the availabilty of iron, magnesium and manganese.
Calcium carbonate makes limestone, while magnesium carbonate makes dolomite.
Calcium Carbonate has a PH of about 9-10
Dolomite limestone is a mixture of calcium carbonate and magnesium carbonate.

If it contain magnesium but no calcium then it would be magnesite.
Limestone.
The proposed method of making magnesium carbonate can not be accomplished from solutions in water, because the solubility of calcium carbonate in water is so low that it can not furnish a sufficient concentration of carbonate ions to exceed the solubility product constant for magnesium carbonate.
Calcium carbonate is generally a stronger acid than magnesium carbonate. This is because calcium is positioned higher in Group 2 of the periodic table than magnesium, meaning calcium has a greater tendency to lose its outer electrons and behave as an acid.
I was wondering how to write a word equation of the reactions that occurred between the acid and the respective active ingredients of each of the different antacid powders.i used t he following acntacids;Gastrogel-Magnesium Hydroxide, Aluminium HydroxideSandocal-Calcium Carbonate, Calcium Lactate, GluconateRennie-Calcium Carbonate, Magnesium CarbonateMylanta Double-Magnesium Hydroxide, Aluminium HydroxideMylanta-Magnesium Hydroxide, Aluminium HydroxideDewitt's-Calcium Carbonate, Magnesium Carbonate Sodium Bicarbonate Magnesium Hydroxide
The products are calcium and magnesium chlorides, water and carbon dioxide.
