(PDF) Groundwater aggressiveness assessment according to

Water aggressiveness can be caused by the water acidity itself (low pH value, presence of free acids) or by binding of calcium into complex compounds. Carbon dioxide in aggressive form could react with the calcium carbonate (CaCO 3 ) or calcium hydroxide (Ca(OH) 2 ) present in the concrete, creating soluble calcium bicarbonate Ca(HCO 3 ) 2 .

Differences between hydrated lime and quicklime - Sodimate

The difference between Calcium oxide and Calcium hydroxide is that CaO has a heavy density (1 g/cm³) and is more reactive than hydrated lime which has the density of 0,5 g/cm 3. It is necessary for calcium oxide (quicklime) to be slaked in a controlled environment because it can create heat that reaches up to 50 degrees Celsius.

Ionic Compounds Containing Polyatomic Ions

Rules for Naming Ionic Compounds Containing Polyatomic Ions. Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO 3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
