Detailed Product Description: | Jing Chi Bose equipment operators | [Ni] light reagents | reagents provided by Jing Chi Bose equipment operators. We are Dongguan Changan Jing Chi Bose equipment operators (www.jingchb.com) at: Dongguan, Guangdong specialized in: Bose equipment, plastic products, laboratory supplies, hardware, labor, and office supplies. Phenol molecule by a hydroxy group directly attached to the benzene ring. According benzene Kekule formula, the hydroxyl groups are attached to the double bond of the enol structure. However, due to the stability of the benzene ring, such a structure is hardly converted to the keto form. Phenol resonance structure as above right. An oxygen atom of a phenolic hydroxyl group using sp hybridization, provides one to six carbon atoms with lone electron delocalized phenyl ring together form a bond. Large π bond strengthened acidic alcohol, pushing electronic effects hydroxyl citric acid reagent has strengthened polar OH bonds, and therefore hydrogen phenolic hydroxyl groups can be ionized out. Product Code: 31410275316 Product Name: Disodium EDTA Spec: 1 Product Memo: a product category :( a) chemical agents [Level]: PT [Structure]: HOOCH2C CH2COONa N-CH2-CH2-N HOOCH2C CH2COONa [ Character]: for odorless or brackish white or white crystalline or granular powder.
