Is h2so3 a conjugate acid or base
Is H2SO3 a conjugate acid?
In this case, sulfurous acid has two protons to donate. However, the conjugate base of sulfurous acid will be the compound left behind after the first hydrogen ion is donated. The compound left behind after sulfurous acid donates its first acidic hydrogen is called the bisulfite anion, HSO−3 .
Is H2CO3 a conjugate acid or base?
A conjugate acid is a substance that is formed when a base receives a proton, or H+. Carbonic acid, or H2CO3, will be the conjugate acid of hydrogen carbonate.
Is H2SO3 an acid or base?
weak acid
Sulfurous acid, H2SO3, is a weak acid capable of providing two H+ ions (pKa1 = 1.9, pKa2 = 7.0).

Is H2CO3 a conjugate acid of HCO3?
HCO3^- is a conjugate acid of H2CO3 .
Are HCO3 and H2CO3 conjugate acid base pair?
The carbonic acid is considered conjugate acid; while losing proton, it forms the conjugate base of the corresponding acid. Thus, yes, H2CO3 H 2 C O 3 and HCO−3 H C O 3 − are the conjugate acid-base pair.
Is H2SO4 and H2SO3 a conjugate acid base pair?
Answer and Explanation: Only Choice E. NH3 and NH4 + is a conjugate acid-base pair.
Is HBr an acid or base?
acid
Although the Br − ions derive from a strong acid (HBr), the NH 4 + ion derives from a weak base (NH 3), so the solution will be acidic, and NH 4Br is an acidic salt.

Is HCO3 an acid?
HCO3– is both an acid or base, depending on the strength of reacting compound. In presence of a strong base like OH–, HCO3– acts as an acid. In presence of a strong acid like HCl, HCO3– acts as a base.
Is H2CO3 and co32 a conjugate pair?
Answer and Explanation: Here, H2CO3andHCO−3 H 2 C O 3 a n d H C O 3 − are conjugate acid-base pair. Therefore, H2CO3andCO2−3 H 2 C O 3 a n d C O 3 2 − are not conjugate acid-base pair.
Is H2SO4 acid or base?
| Strong Acids | Strong Bases |

| HCl (hydrochloric acid) HNO3 (nitric acid) HClO4 (perchloric acid) H2SO4 (sulfuric acid) | NaOH (sodium hydroxide) KOH (potassium hydroxide) Ca(OH)2 (calcium hydroxide) |
What is H2SO4 conjugate base?
The conjugate base of H2 SO4 is HSO4 –. H2 SO4 loses a proton (H+) to form the conjugate base.
Is CO32 a conjugate base?
CO32- would not have a conjugate base, as it cannot lose any more hydrogen atoms.
What is the conjugate acid of clo3?
Chlorate is a monovalent inorganic anion obtained by deprotonation of chloric acid. It is a monovalent inorganic anion and a chlorine oxoanion. It is a conjugate base of a chloric acid.

Is HCO3 a strong acid?
H2CO3 is a weak acid and does not completely dissociate. The product, HCO3-, is not stable and can react again with water to contribute to the pH. HCO3- will act as a base by plucking off the proton from H2O, and forming a basic solution.
Is co32 an acid or base?
Carbonate ion, a moderately strong base, undergoes considerable hydrolysis in aqueous solution. In strongly acidic solution, CO2 gas is evolved.
What is the conjugate acid of nh2?
1 Expert Answer
The conjugate acid has one proton (H+) more. Hence, for NH2– the conjugate acid would be NH3 (the positive charge of H+ and the negative charge of NH2– cancel each other out).
What is the conjugate acid of HBr?
H3O+
Similarly, when a basic substance gains a proton it forms an acid known as conjugate acid of base. Thus, HBr lost a proton to form Br−. So, Br− is the conjugate base and H3O+ is the conjugate acid of HBr.
Is co32 a Lewis acid?
[CO3](2-) is carbonate ion. It can accept a proton (H+) to form bicarbonate ion, [HCO3](-), making carbonate ion a Bronsted-Lowry base. Since the proton binds by accepting an electron pair from carbonate ion to form a bond, carbonate ion is also a Lewis base.
Is HBr a brønsted-Lowry acid?
The HBr is a Brønsted acid, and the water is a Brønsted base. In the Brønsted-Lowry theory, a conjugate base is whatever is left over after the proton has left. Thus, HBr lost a proton to become Br⁻, so Br⁻ is the conjugate base of HBr.
Is HCO3 a conjugate base?
The conjugate base of HCO3 – is CO3 -2, which is the carbonate ion. To determine the conjugate base of a substance, you remove one hydrogen ion.
Is Mn2+ A Lewis base?
Mn2+ is expected to accept an electron pair because it is positively charged. (b) Lewis base. CH3NH2 is anticipated to donate an electron pair. The N atom has a long electron pair with which it can form a bond with a Lewis acid.
