Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene).
The company was launched in 2014. [1] Its name, Vedantu, is derived from the Sanskrit words Veda (knowledge) and Tantu (network). [2] The organization is run by IIT alumni Vamsi Krishna (co-founder and CEO), Pulkit Jain (co-founder and head of product), Saurabh Saxena (co-founder) and Anand Prakash (co-founder and head of academics).

On 23 February 2022, a public interest litigation petition was filed the Madras High Court seeking a direction to the State government to adopt the National Council of Educational Research and Training (NCERT) syllabus for State Board schools. The petitioners claimed that Samacheer Kalvi was not helping the students crack the competitive exams.
An example of the Hell–Volhard–Zelinsky reaction can be seen in the preparation of alanine from propionic acid.In the first step, a combination of bromine and phosphorus tribromide is used in the Hell–Volhard–Zelinsky reaction to prepare 2-bromopropionic acid, [3] which in the second step is converted to a racemic mixture of the amino acid product by ammonolysis.
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula . For example, a solution of table salt , also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq) .
The reaction mechanism proceeds via an ene reaction with chromyl chloride, forming the precipitated Étard complex.The Étard complex is then decomposed by a [2,3] sigmatropic rearrangement under reducing conditions to prevent further oxidation to a carboxylic acid.
It is often combined as a solid solution with hydroxylapatite (Ca 5 (PO 4) 3 OH or Ca 10 (PO 4) 6 (OH) 2) in biological matrices. Chlorapatite (Ca 5 (PO 4 ) 3 Cl) is another related structure. [ 5 ] Industrially, the mineral is an important source of both phosphoric and hydrofluoric acids.
