it is because no sharp change in pH is detected at the euivalence point,none of the indicator suits for it...
Since they are both acids, you don't usually titrate one against the other. If you want to titrate something, you should use one acid and one base. If one of them is a weak acid/base, the other should be a strong acid/base.So if you want to titrate a solution of acetic acid, use a solution of a known concentration of sodium hydroxide (NaOH) or potassium hydroxide (KOH) instead. You can also use either of those two strong bases to titrate a solution of perchloric acid.
NaHCO3 is a weak base, with a conjugate acid of H2CO3+.
If you are aiming for a specific pH they require less of a base. If you need to simply full titrate it, it depends on how much of the acid you have, not how strong it is.
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.
HCOO- is the conjugate base of formic acid (HCOOH) which is a weak acid. Therefore, HCOO- is a weak base.

The formic acid is a weak acid.
In order to have an effective buffer, one needs to have a weak acid or a weak base, and the salt (conjugate) of that weak acid or weak base. Examples would be :weak acid/conjugate base: acetic acid/sodium acetateweak base/conjugate acid: ammonia/ammonium chloride

To prepare a buffer solution which may be acidic. Titrate ethanoic acid (weak acid) with sodium ethanoate(salt).
HCOO- is the conjugate base of formic acid (HCOOH) which is a weak acid. Therefore, HCOO- is a weak base.
CH3COOH is a acid. It is a weak acid.
A solution containing a weak acid and its salt will act as a buffer, maintaining the pH by neutralizing added acid or base. Similarly, a weak base and its salt can also function as a buffer. Weak acid-weak base buffer systems are commonly used in chemical laboratories and biological systems to control pH fluctuations.
No, HNO2 is a weak acid, not a weak base. It is a weak acid because it only partially ionizes in water to release H+ ions.
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.
