Does a weak acid gain a proton?
No, a weak acid donates a proton (H+ ion) when it dissociates in water, rather than gaining one. This donation of a proton is what causes the weak acid to ionize and form its conjugate base.
Do Furan is weak base Or strong base?
Furan is a weak base. It is a heterocyclic compound that contains oxygen in its ring structure, making it less basic than typical amines due to the lower availability of lone pair electrons for proton donation.
What would be the conjugate pair for a strong base?
The conjugate pair for a strong base is a weak acid. When a strong base, such as sodium hydroxide (NaOH), dissociates in water, it produces hydroxide ions (OH⁻), which can then react with a weak acid to form its conjugate base. For example, if we take the strong base sodium hydroxide, its conjugate pair would be the weak acid water (H₂O), which can donate a proton to form hydroxide ions. Thus, the conjugate acid-base relationship involves a strong base and its corresponding weak acid.
Why pyrrole is a weak base?
Pyrrole is an extremely weak base because its pair of non-bonding electrons are part of the π-cloud (Kb = 2.5 x 10-14). Therefore, if pyrrole is protonated, it loses its aromaticity as the non bonding electrons are no more available for delocalization to form the aromatic sextet.
What is the pka of pyridine?
The pKa of pyridine is approximately 5.2. It is a weak base due to the lone pair of electrons on the nitrogen atom, which can accept a proton to form the conjugate acid.
Does a weak acid gain a proton?
No, a weak acid donates a proton (H+ ion) when it dissociates in water, rather than gaining one. This donation of a proton is what causes the weak acid to ionize and form its conjugate base.
What is the relationship between a weak acid and its conjugate base in a chemical reaction?
In a chemical reaction, a weak acid and its conjugate base are related as a pair. When the weak acid donates a proton, it forms its conjugate base. The conjugate base can then accept a proton to reform the weak acid. They exist in equilibrium, with the weak acid and its conjugate base acting as partners in the reaction.
Is (CH3)3N a strong or weak acid or base?
(CH3)3N, also known as trimethylamine, is a weak base. It can accept a proton to form the ammonium ion, but it does not readily donate a proton like a strong base would.
Which statement always accurately describes acids and bases a the conjugate base of a weak acid is a strong base b the conjugate acid of a weak base is a weak acid c strong acids and st?
b) The conjugate acid of a weak base is a weak acid. When a base accepts a proton to form its conjugate acid, it tends to be a weak acid because it does not easily donate a proton back. This relationship is governed by the principles of acid-base equilibrium.
Is Na2HPO4 amphiprotic?
Yes, Na2HPO4, known as disodium hydrogen phosphate, can act as a weak acid and donate a proton to a base, behaving as an amphiprotic species. It can also act as a weak base and accept a proton from an acid.
Is NH3 a base?
Yes, NH3 (ammonia) is a weak base. It can accept a proton (H+) from water to form the ammonium ion (NH4+).
Is NCH3H2 a strong or weak base?
NCH3H2 is a weak base. It is a weak base due to the presence of the nitrogen atom that can donate a pair of electrons to accept a proton, but it is not as readily able to do so as a strong base like hydroxide (OH-).
Is C5H5N a base or acid?
C5H5N is a weak base. It can accept a proton (H+) to form the conjugate acid C5H5NH+.
Is HCO3 a weak or strong acid?
HCO3 is not an acid, but a base. It is the conjugate base of the weak acid H2CO3 (carbonic acid). In water, it can act as a weak base by accepting a proton to form H2CO3.
Ammonia Nh3 is a weak?
base, meaning it can accept a proton (H+) to form NH4+ and OH-. It acts as a weak base in water, forming the ammonium ion (NH4+) and hydroxide ion (OH-).
Is ammonia a strong alkali?
Yes, ammonia is a weak alkali. It is a weak base that can accept a proton to form the ammonium ion.
Is ammonia a weak acid?
Ammonia typically acts as a weak base. In most acid-base reactions involving ammonia, the nitrogen atom gains a proton and gains a positive charge. The result is the ammonium cation.
