Nitrógeno, preparación y propiedades

Principle

Nitrogen as a major component of  air can be obtained from it by removing the oxygen. In this experiment an air stream is passed over heated steel wool and passed into a pneumatic pan. This so "produced" nitrogen is examined for its characteristic properties ...

La oxidación- "combustión lenta"

Principle

Many students combine the term "oxidation" with a combustion reaction. This student experiment explains that oxidation also proceed "unspectacular" over longer periods. This experiment shows iron wool corrodes in moist air, it rusts. Rusting is "slow ...

Reducción del óxido de cobre

Principle

In this experiment the reduction of copper oxide to copper is examined (reduction as an inverse process of oxidation). Students know that many oxides (caused by a thermal reaction of atmospheric oxygen with an element) can not be decomposed thermally in a simple manner to the pure ...

Soluciones, coloides suspensiones

Principle

Mixtures of solids and water form in physically different ways. Depending of the degree of dispersion one can differentiate between solutions, colloids and suspensions.

Tasks

Mix several substances in water and investigate the resulting types of ...

Solubilidad de sales en agua: comparación de la solubilidad de gases en agua

Principle

In contrast to gases, the higher the temperature of the water, the better salts dissolve in it. By supercooling them, metastabile supersaturated solutions can be prepared which exhibit a higher concentration than that corresponding to the thermodynamic equilibrium quantity at a ...

Dureza del agua

Principle

Under hardness of water is understood the amount of dissolved salts (calcium salts and magnesium salts). The higher the amount of dissolved salts the "harder" the water. This can also be applied to drinking water,  drinking water can be devided in accordance with the ...
