Corrosion inhibition of indole-3-carboxylic acid (ICA) on mild steel in 0.1M H2SO4 solution has been studied through weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and scanning electron microscope (SEM) experiments. Plots from polarization and EIS techniques ...
Synthesis of hydroxy derivatives from adamantanecarboxylic acids in the system MnO2–H2SO4Synthesis of hydroxy derivatives from adamantanecarboxylic acids in the system MnO2–H2SO4A convenient procedure has been developed for the synthesis of mono- and dihydric cage alcohols from adamantanecarboxylic acid...

Is H2SO4 a carboxylic acid? If it is not a carboxylic acid, what can it be? For each pair of acids, a state in which acid is a stronger acid, and briefly explain. CF_3 COOH and CHF_2 COOH Why are alkynes considered acidic and also considered good nucleophiles? Aren't bases suppos...
The aqueous samples are adjusted to pH 2 with H2SO4 and extracted with diethyl ether. The ether is allowed to evaporate over distilled water. The acid concentrate is analysed using a Zorbax-ODS column (25 mm 4.6 mm). The method is simple, fast, and because of the selectivity of the ...
The answer is: (1,4) 5. One example of this is the production of cyanohydrin from a ketone. addition of electrophilic inclusion of nucleophiles Replacement of nucleophiles Replacement of electrophiles The answer is: (2) 6. Conc.HNO3 and conc.H2SO4 react with benzoic acid to form o-nitrobe...
