Effect of calcium carbonate (CaCO3) in water can also be expressed as the hardness of the ability of water to form foam when mixed with detergent (soap). On the water has a low hardness will easily form foam when mixed with soap. While on the water that has high hardness would not form foam. Hardness is very important for the ...

Soil Structure Formation

There are two stages that occur in the formation of soil structure, namely (1) clotting (coagulation) of colloidal soil as a result of the influence of Ca2 + ions into the soil micro-aggregates, and (2) cementation (binder) micro aggregate into the aggregate macro. Meurut soil structure formation theory, based on the flocculation occurs on land that is in solution, for ...
