Q 12 MWG with x-approach

In this second screencast on the calculation with the law of mass action, an example problem is calculated using an x-approach. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

Q12 Autoprotolysis of water

The law of mass action is applied to the autoprotolysis of water. Through further considerations, a constant Kw can be defined. This is called the ionic product of water. This is the basis of the pH value. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done

Q 11 Mutarotation in glucose

alpha-glucose and beta-glucose are in balance. This can be demonstrated by measuring the angle of rotation of linearly polarized light. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

Q12 Acid Base Buffer

Acid-base buffers are briefly explained, as well as the buffering effect. The main point of the screencast, however, is the pH value calculation in the buffer range. Furthermore, it is described how buffer systems are formed in titrations of weak acid with a strong base. Original: "Wolfgang Dukorn"

Q12 KB and pKB value

In this screencast, the base strength is explained very briefly. KB and pKB values are introduced. At the end, the relationship between acid and base starch is explained. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

09 Stoichiometric Calculations - Example Task

On the basis of an example problem, the stoichiometric calculations in chemistry are explained. It calculates the mass of a product when only a certain mass of a starting material is available. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugh
