Separación de una mezcla de líquidos por destilación

Principle

The separation of liquid mixtures can be achieved by a simple distillation.  In this experiment a liquid mixture of water and ethanol is distilled by using a distillation column. Various fractions of the distillate are obtained with the help of a rotatable receiver. The ...

Combustión rápida: explosiones

Principle

This experiment shows that the combustion rate depends on the degree of dispersion and the mixing with oxygen (or the oxidizing agent). Students observe that metals such as aluminum and magnesium are  non-flammable in compact form or when they burn , they burn ...

Sistemas químicos metaestables y energía de activación

Principle

This experiment shows that exothermic reactions start not always spontaneous when two (or more) substances are mixed together. Students realize that no reaction occurs when the reactants (in solid state) are mixed together. The solids usually begin to react with each ...

Enlace del nitrógeno por metales base

Principle

In this experiment the reactivity of nitrogen with various metals is investigated. Nitrogen as a typical non-metal should react with metals to the corresponding salt in the form of an exothermic reaction. However metals react only very little with nitrogen. Nitrogen reacts at room ...

Soluciones salinas: reacciones ácidas, neutras y alcalinas

Principle

The pH-value of a prepared salt solution can be predicted by the strength of the acids and bases which are part of the salt solution. Salts of equally strong acids and bases (e.g., NaCl) react neutral in aqueous solution. Salts of a weak acid / base and strong base / ...

Tautomería ceto-enol del acetoacetato de etilo

Principle

Keto-enol tautomerism is understood in chemistry as the equilibrium between the structural form of an aldehyde and a ketone (the compounds must be constitution isomers). The name "enol" reflects the double bond (-en) and the OH group (-ol) in the molecular structure.

In this ...
