Introduction Titration is a quantitative analysis used in chemistry used to identify the strength or concentration of a given unknown chemical solution by analysing it with a known solution concentration with the presence of an indicator. Both oxidation and reduction happen at the same time. Titration is a process for calculating the quantity of one unknown solution concentration by other solutions. An Indicator is required to detect the endpoint of equivalence. It generally occurs with colour change. What is Titration? Chemical reaction occurs with the interchange of ions when certain chemical species are in contact with each other. Titration ... Read More

Introduction Ununoctium is the temporarily given IUPAC name which helps to identify the chemical element. Scientists know very little about it; however, it is considered as super heavy element with an atomic number of 118. The atomic number and atomic mass of the discovered element is the highest. What is Ununoctium? The former name of element 118 is Ununoctium, which is also known as the eka-radon. Ununoctium is a temporary IUPAC name for the synthetic element and it is super heavy non-metal. It is not free in the planet and hence, called as the artificial element. The term ununoctium is ... Read More

Introduction Ullmann reaction is a coupling reaction between aryl halide molecules. Fritz Ullmann was a German chemist who first noticed this type of reaction and this reaction is called the Ullmann reaction after his name. Copper plays an important role throughout the entire coupling mechanism. Meaning of Ullmann Reaction Ullmann coupling or Ullmann reaction means a reaction is carried out for coupling two aryl halide molecules for the formation of biaryl compounds using some thermal conditions and copper catalyst. There are different reaction mechanisms for Ullmann reactions and two of them are very popular. In the radical mechanism process, an ... Read More
