A)What is the conjugate base of HSO3− ? B)What is the conjugate acid of HPO42− ? C)Of the conjugate acid-base pairs HF/F− , HCl/Cl− , and HCN/CN− , complete the following equation with the pair that gives an equilibrium constant Kc > 1. −−−−−+H2PO−4 −−−−−+H3PO4 .

2016年2月28日 · I think HSO3 acts as a base because it donates a pair of electrons and this is another definition when you think of acids and bases. An acid is a substance that accepts a pair of electrons whereas a base is a substance that donates a pair of electrons.

2023年6月14日 · Initial calculations indicated that the hydrogen sulfonate form, $\ce{HSO3−}$, is the most stable form of the tautomers. However, Hoffmann has argued that the chemical reactivity of bisulfite ions in aqueous solutions is consistent with $\ce{HO\bond{−}SO2−}$ being the major reactive tautomer, which is in rapid equilibrium with $\ce{HSO3 ...

Identify the conjugate base of HSO3-1 in the following reaction. HSO3-1(aq) + H2O(aq) ⇄ SO3-2(aq) + H3O+(aq) a. HSO 3-1. b. H 2 O. c. SO 3-2. d. H 3 O + What is the hydroxide ion concentration, [OH-], in an aqueous solution where the hydronium ion concentration, [H 3 O +], equals 0.135 M: [H 3 O +] = 0.135 M? {[H 3 O +] [OH-] = 1.0 x 10-14} a ...

Consider the reaction: H2SO3 + HCO3- H2CO3 + HSO3- a) Identify the acid, base, conjugate acid and conjugate base b. What is the conjugate base of water? c. ) What is the value of [H3O+] in a solution with pOH = 10.82? d. What is the pH of a solution with [H3O+] = 5.9 × 10-3 M

Question: 1. HSO3 ¯ is amphoteric. For H2SO3 Ka1 = 1.4 x 10-2 and Ka2 = 6.3 x 10-8 . a. Write a chemical reaction showing HSO3 ¯ acting as an acid in water. b. Write a chemical reaction showing HSO3 ¯ acting as a base in water. c. Will an aqueous solution of NaHSO3 be acidic, basic, or neutral?

2015年9月30日 · There are two distinct forms of $\ce{HSO3-}$ (see picture below; all horizontal bars are formal $-$ signs). Only the leftmost of these two forms can be called hydrogen sulphite (or ‘bisulphite’, if you really insist); the correct name of the rightmost form is sulphonate. The two differ in their chemical characteristics; hydrogen sulphite is ...
