Catalasas

 Principle
Animal and vegetable foods contain the enzyme catalase. Catalases split hydrogen peroxide into oxygen and water.
Enzymes are high molecular protein compounds which can be denatured by heat and heavy metal ions. Catalase is detected in various foods.

Presión de una solución

Principle

The metals zinc and copper tend to dissolve in water to a certain extent. This tendency can be designated as "solution pressure". On dissolving, metal atoms on the surface of the metal electrodes pass into the ionic state. In this experiment students realize, that when two electrodes ...

Celda/pila de cobre y Zinc (Bateria de Daniell)



Principle

A complete galvanic cell is to be set up in this experiment. The terms potential and potential difference can be introduced. In a complete "galvanic cell", two electrodes of different metals each dip in an aqueous solution of one of their own salts. In a copper/zinc cell, ...

Mediciones de los potenciales redox standard Fe3+/Fe2+



Principle

It is well known that iron(III) ions can be reduced to iron(II) ions by suitable reducing agents. The driving force behind such an ionic reloading can be measured as the standard potential of an appropriately constructed galvanic cell. We therefore require for such a ...
