H2SO3 donates a proton , therefore it is an acid. While , HCO3- accept a proton ,so it is base. in the right hand side of the equation, HSO3- is base because it accepts a proton while ,H2CO3 is an acid because it donates proton. The formula for the conjugate base of H2SO3 will be HSO3- .
You are watching: What is the conjugate base of h2so3?
Is H2SO3 a conjugate acid or base?
Sulfurous acid is a sulfur oxoacid. It is a conjugate acid of a hydrogensulfite. It is a tautomer of a sulfonic acid.
What is the conjugate acid of HSO3 −?
PO can’t be a conjugate acid because it has no H in the formula. All of the others are conjugate acids. To determine what each one’s conjugate base is, remove one H and reduce the charge by 1 (i.e., subtract 1 from the original charge). So, for example, the conjugate base of HPO is HPO.
What are the conjugate bases in the following reaction H2SO4 h2o → HSO4 H3O+?
H2SO4/HSO4- is an acid/conjugate base pair. H20 is the base in the forward rxn, because it accepts a proton, and becomes H3O+. H20/H3O+ is a base/conjugate acid pair.
Which of the following is a conjugate acid base pair?
HOCN and OCN- are an example of a conjugate acid-base pair. The only difference between the two is a proton (H+). All acids have a conjugate base and all bases have a conjugate acid.
What is the conjugate base of water?
What is the conjugate base for H2PO4?
What is the conjugate acid of the weak base H2PO4?
The NH4 is an acid because it donated a proton to HPO4. HPO4 is a base because it received the proton. H2PO4 is a conjugate acid because it’s a base that gained a proton. NH3 is a conjugate base because it’s an acid that lost a proton.
What is the conjugate acid of CN?
Hence HCN is the conjugate acid of cyanide ion.
Can cn be an acid?
Strong acids have weak conjugate bases Similarly, the CN– ion binds strongly to a proton, making HCN a weak acid.
What is the conjugate acid of O2?
What is the conjugate acid of CH3COO?
CH3COOH is a weak acid and dissociates partially in solution (as indicated with reversible arrow) to form H+ and CH3COO- ions. Since this is a reversible process, CH3COO- can accept H+ to form back CH3COOH. Therefore the nature of CH3COO- is basic and we call CH3COO- the conjugate base of CH3COOH.
Is the conjugate base of a weak acid strong?
The conjugate base of a weak acid is usually a strong base. The conjugate base of an acid is the anion that results when the acid molecule loses its hydrogen to a base.
Why are weak acids reversible?
Strong acids and strong bases refer to species that completely dissociate to form ions in solution. By contrast, weak acids and bases ionize only partially, and the ionization reaction is reversible. Thus, weak acid and base solutions contain multiple charged and uncharged species in dynamic equilibrium.
