Without going into the details of what Arrhenius said an acid is, or how Lewis (if I got my names right) defines it, I will use the “classical” idea of what acids are: molecules with some hydrogen atoms protonic acid is the chemical compound that dissociates to give a proton in aqueous solution . So basically any acid is usually protonic but there are exceptions . Examples can be HCl, HNO3, H2SO4, H3PO4 etc… Feb 03, 2021 · Protonix (pantoprazole) is a proton pump inhibitor that decreases the amount of acid produced in the stomach. Protonix is used to treat erosive esophagitis (damage to the esophagus from stomach acid caused by gastroesophageal reflux disease, or GERD) in adults and children who are at least 5 years old.

Which one of the following compounds is not a protonic acid :- (1) B(OH), (2) PO(OH) (3) SO(OH), (4) SO,(OH) Polyphosphoric acid is a protonic acid, which can dissolve a variety of low molecular and high molecular organic compounds. Used as a catalyst or solvent for condensation, cyclization, rearrangement, substitution and other reactions. The protonic acid sites remained stable up to 348 K, but the Lewis acid sites had just started to evolve. By further heating, the acidic character eventually switched back to the initial state where the Brønsted acid sites were at a relatively small concentration and the Lewis acid sites dominated. An acid that forms positive hydrogen ions (or, strictly, oxonium ions) in aqueous solution. The term is used to distinguish ‘traditional’ acids from Lewis acids or from Lowry-Brønsted acids in nonaqueous solvents.

The term is used to distinguish ‘traditional’ acids from Lewis acids or from Lowry-Brønsted acids in nonaqueous solvents. Propionic acid (/ p r oʊ p i ˈ ɒ n ɪ k /, from the Greek words protos, meaning "first", and pion, meaning "fat"; also known as propanoic acid) is a naturally occurring carboxylic acid with chemical formula CH 3 CH 2 CO 2 H. It is a liquid with a pungent and unpleasant smell somewhat resembling body odor. Protonix (pantoprazole) is a proton pump inhibitor that decreases the amount of acid produced in the stomach. Protonix is used to treat erosive esophagitis (damage to the esophagus from stomach acid caused by gastroesophageal reflux disease, or GERD) in adults and children who are at least 5 years old.

While protonic acid doping occurs in polyaniline, conjugated polyions offer synthetic tunability and selective processing into insulating, semiconducting and The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.

Oct 13, 2020 Oct 16, 2014 Boric acid B (O H) 3 is not a protonic acid. It is a Lewis acid. It behaves as an acid by accepting a pair of electrons from a suitable Lewis base.
