Q 12 The standard potential

With the help of the standard hydrogen half-cell, the potentials of all other half-cells can be determined. The standard hydrogen half-cell represents the defined 0-point. Therefore, these measured potentials are referred to as standard potentials. Original: "Wolfgang Dukorn" Original: German. All

09 What is hydrochloric acid

Hydrogen chloride gas (HCl) is discharged into water. This produces hydrochloric acid, which is also described with the formula HCl. But what is the difference between these two substances? Why do you have the identical formula? Original: "Wolfgang Dukorn" Original: German. All translations in thi

How Do You Split An Atom?

There are certain scientific concepts out that that most people have heard of, but don’t quite know what it implies. While you’ve doubtlessly heard mention of splitting an atom in school or films, you may have missed out on how exactly this can be done. So let’s explore the wonderful world of nuclea

08 Lewis Formulas Without Practice

How are Lewis formulas (valence formulas) set up? The electron octet (duplet for hydrogen) and the total number of electrons must be observed! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

08 Isotopes

Different isotopes of the elements can exist. These have a different mass number, but identical proton number. This is explained in the screencast and discussed again at the end using the example of hydrogen. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been do
