Description:Tetramethylammonium hydroxide is a strong base that is used in analytical chemistry for the quantitative determination of zirconium. It is an analytical reagent and has a pH of 14. Tetramethylammonium hydroxide forms complexes with metals such as zirconium and titanium, which are then analyzed by various methods such as atomic absorption spectroscopy, x-ray fluorescence spectroscopy, and inductively coupled plasma mass spectrometry. The optimum concentration of tetramethylammonium hydroxide for this application is approximately 25%. Tetramethylammonium hydroxide reacts with p-nitrophenyl phosphate to form a pink product, which can be detected by colorimetric analysis. This reaction also produces hydrogen fluoride gas, which must be removed before the solution can be used again. Tetramethylammonium hydroxide reacts with ammonium to form tetramethylammonium ion and water. It also reacts
