The reaction of Hydrogen peroxide as a base doesn't yield a salt, it's the acid that yields the salt. Identify the acid, base, conjugate acid and conjugate base in this reactions HClO4(aq) + H2O(l) ⇄H3O+(aq) + ClO4-(aq) Explanation Any reaction is which a proton trasfer takes place from one substance to another is an acid-base reaction.More specifially the proton transfer view is know as the bronsted-lowry defincation of acids and base. It is prepared by the reaction of hydrogen peroxide with nitrite: . Conjugate base of weak acid. Acid is acetic . b. Sign In. A conjugate acid is a substance that is formed when a base receives a proton, or H+. an Arrhenius acid. MSDS - See attached file 4. N H 3. CHEBI:16240. It is a conjugate base of a hydrogen peroxide. The Ka value for H2O2 is 1.55 X 10-12. Strong acid forms a weak conjugate base and vice versa. The hydroxide acts like a Bronsted Lory base, so it can catch a proton. Hence, the conjugate base of propanoic acid, is, Advertisement Advertisement New questions in Chemistry. Conjugate acid-base pairs usually have a difference of one hydrogen atom or a proton. Chemistry. What is the conjugate acid of H2PO4-(aq)? Hydrogen Peroxide has a pKa of 11.62, meaning it's a strong base as has already been pointed out. Answer (1 of 3): Always confused between the conjugate acid base concept. The copper(II) complexes 1 H and 1 Ar(X), supported by the N,N-di(2-pyridylmethyl)benzylamine tridentate ligand (L H) or its derivatives having m-substituted phenyl group at the 6-position of pyridine donor groups (L Ar(X)), have been prepared, and their reactivity toward H 2 O 2 has been examined in detail at low temperature. All Chemistry Practice Problems Conjugate Acids and Bases Practice Problems. NH 3 is a weak base, but its conjugate acid, NH 4 Cl, is a strong acid. Number of Field Applications: 15 (estimated) 5. Hydrogen peroxide is acid as it has a pH value below 7. H 2 O 2 + NO − 2 → ONOO − + H 2 O . Answer (1 of 2): Adding one H+ to anything gives you its conjugate acid. In a water solution, sodium citrate dissociates into sodium ions and citric acid. The conjugate base of an acid is the substance that remains after the acid has donated its proton.Example: Acid is HX and conjugate base is X^-. What does h2o2 and NaOH do in a reaction?
