The pH value calculation for weak acids (and bases) is explained. This is more demanding than with strong acids and bases. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
The pH value calculation for strong acids is described. In the end, also for strong bases. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
This screencast discusses the mathematical derivation of pH and pOH. The ionic product of the water is decisive for this. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Learn the basics about the pH scale, universal indicator and litmus paper. Indicators tells if something is acidic, alkaline or neutral. Indicators are substances that show different colours when they are in acidic or alkaline conditions. Litmus paper is a simple indicator that tells us whether so
If salts are dissolved in water, they can form an acidic, neutral or alkaline environment. The formation of oxonium ions or hydroxide ions is explained. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Learn the basics about Indicators, more specifically for acid and bases. An indicator is a large organic molecule that works somewhat like a " color dye". Find out more in this video! This Open Educational Resource is free of charge, under a Creative Commons License: Attribution-NonCommercial CC BY
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
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"
