B) ClO3-. 2. A strong Brønsted-Lowry acid is one which has strong tendency to donate a proton 3: Strong acids include H 3 O +, HCl and HNO 3. B) HSO4. So what is the oxidation state of chlorine in this chlorous acid? View Answer. H2PO4- can act as an acid, too. 4, H. 2. It is the substance that gets created once a acid looses a [H+] proton ; This is all known as a conjugate acid-base pair. Concept introduction: According Bronsted-Lowry acid and base theory, acids are substance which loses protons H + to form conjugate base and bases are substances which accepts protons to from conjugate acid. Which is the stronger base in each pair? Please do not block ads on this website. O) is dissolved in water, the solution turns basic from the reaction of the oxide ion (O. E) HSO3-. Source(s):-Chem-gee the question did not ask for the conjugate base of HSO4-, it asked for HClO3; so the answer to the question is: conjugate base of HClO3 is ClO3-.-And yes the reaction is reversible so they can look at the problem as HClO3 as a reactant rather then a product. Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO −.HClO and ClO − are oxidizers, and the primary disinfection agents of chlorine solutions. The formula for the conjugate base of HClO is: 2. For example, in water, a strong acid like hydrochloric acid readily donates a proton to a water molecule: E) HClO. When lithium oxide (Li. It should read: HClO_2 + H_2O rightleftharpoons ClO_2^(-) + H_3O^+ You know that the conjugate base of an acid is the anion after protonation of water. 12. C) Cl(OH)2. D) H2SO4-. HClO cannot be isolated from these solutions due to rapid equilibration with its precursor. D) ClO3. View Answer. For example: HA → H + + A − S, PH. View Answer. EX: ClO−+ H2O → HClO + OH− In this equation, H2O is the acid and ClO is the base. You further know that a base accepts a proton, and an acid donates a proton. The formula of the conjugate base should be determined. This is a weak acid as acids go; perchloric acid HClO_4 (oxidation state of Cl?) Which halogen forms an oxyacid that contains the halogen atom in tripositive oxidation state? is much stronger; why? 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^-. 13) Which of the following is the strongest acid? The formula for the conjugate acid of CN-is: Expert Answer 100% (1 rating) Previous question Next question Get more help from Chegg. In both cases identify the conjugate acid– base pairs. 1 Answer to 11) The conjugate base of HClO3 is A) HClO2. 11. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. Generally, for the equation HA = H+ + A- HA is the acid (here H3PO4), H+ is H+ and A- is the conjugate base (H2PO4-). C) H2SO4. Explain in terms of the partial charge on hydrogen why NaOH is a base, HClO is a weak acid and HClO 4 is a strong acid. HCIO 4 is a strong acid due to the multiple oxygen bonded to the central atom. Which of the following is strongest conjugate base? No ads = no money for us = no free stuff for you! 12) The conjugate acid of HSO4- is A) SO42-. The correct order of basic character of oxo anions of chlorine is: What is the conjugate base of each of the following acids: HClO. Strong Acid - Weak Conjugate Base Pair. Conjugate Base: Conjugate base is the opposite of a conjugate acid. Why is HCl a strong acid and HClO a weak acid?
