The average number of colors that humans can distinguish is about one million. This situation varies depending on color blindness, or at the other end of the spectrum, depending on the "four color observer"; Rare individuals with genetic mutations can see up to 100 million colors. However, what humans have in common is their ability to recognize changes in green better than any other color. A short explanation for this commonality is the connection between human evolution and the past of our...

1、 Industry Overview Surfactants refer to a class of amphiphilic compounds whose molecular structure is amphiphilic (hydrophilic, hydrophobic, lipophilic). Adding a small amount of them can significantly change the interfacial state of their solution system. One end of the molecule is an lipophilic group (hydrophobic group), and the other end is a hydrophilic group. According to the principle of similar compatibility, when dissolved in water, water has a strong affinity for hydrophilic groups,...

Why is EDTA used in titration? The most common indicator in complexometric titration is organic dye, whose function is to form a colored complex with the metal ions being titrated. During the reaction, EDTA replaces the indicator and forms a more stable complex with metal. When the reaction is completed, the color change can be observed. What iron content can be titrated? EDTA titrates the total iron in the mixture of iron (II) and iron (III). What is EDTA titration? EDTA is the abbreviation of...
