Potassium hydrogen phthalate reaction
Web26 Jun 2024 · Di-2-ethylhexyl phthalate (DEHP) is a toxic plasticizer and androgen antagonist. Its accumulation in water exceeds national drinking water standards and it must be continuously and effectively regulated. Currently, methods used to detect DEHP are still unsatisfactory because they usually have limited detection sensitivity and require … WebThis reaction is a representative of an acid-base reaction. In this case the hydrogen phthalate ion is the acid (proton donor) and the hydroxide ion is the base (proton acceptor). The stoichiometric ratio between the hydrogen phthalate ion and the hydroxide ion, and therefore between the potassium hydrogen phthalate and the sodium hydroxide, is ...
