Hoffman Voltameter
0 out of 5(0)Hoffman voltameter is a laboratory apparatus used for the electrolysis of water (H2O) into its constituent gases, hydrogen (H2) and oxygen (O2). It consists of a glass container filled with water, inverted over two electrodes, typically made of platinum or another inert material, immersed in an electrolyte solution (usually dilute sulfuric acid).
When an electric current is passed through the electrodes, water molecules are dissociated into hydrogen ions (H+) and hydroxide ions (OH-) at the cathode (negative electrode) and anode (positive electrode) respectively. The hydrogen ions migrate towards the cathode and are reduced to hydrogen gas (H2), while the hydroxide ions migrate towards the anode and are oxidized to oxygen gas (O2).
The gases produced collect in the two arms of the apparatus, with hydrogen forming at the cathode and oxygen at the anode. The Hoffman voltameter allows for the collection and measurement of these gases, demonstrating the stoichiometry of water electrolysis, where two moles of hydrogen are produced for every mole of oxygen. This apparatus is commonly used in educational settings to illustrate the principles of electrolysis and the composition of water.

0 out of 5(0)Hydrogen peroxide is a chemical compound with the molecular formula H2O2. It is a colorless and odorless liquid, which appears slightly more viscous than water. Hydrogen peroxide is a powerful oxidizing agent, meaning that it readily releases oxygen atoms in chemical reactions. It is commonly used as a disinfectant, bleaching agent, and in the production of other chemicals. In its pure form, hydrogen peroxide is highly reactive and can be dangerous, but when properly diluted, it can be used safely for a variety of applications.
