Chemical Properties
Magnesium hydroxide:
Magnesium Hydroxide is a very commonly used compound due to its many chemical properties. It is used as a fire retardant due to its non-combustibility (Britannica, 2015), it is used in many laxatives and antacids because it has a pH level of 10.5 which means it is a base that is relatively weaker than other compounds (Chemicalbook, 2008).

Calcium carbonate:
Calcium carbonate shares the typical properties of other carbonates. Notably, it reacts with strong acids and acidic salts to produce carbon dioxide with bubbling. The reaction with concentrated solutions of acids is rapid and exothermic. In addition, when it is heated to above 840 °C, calcium carbonate releases carbon dioxide and decomposes. This is also called a thermal decomposition (Mcgill, 2008). It is also a non-combustible compound (Cameochemicals, n.d.). |
