The following are all examples of good titration reactions with the exception of . (7-2) Group of answer choices Ammonia (NH3) titrated with HCl titrant. Formic acid titrated with ammonia (NH3) as a titrant. I- titrated with Ag titrant, forming a complex with a tiny Ksp. Potassium Hydrogen Phthalate (KHP) titrated with NaOH titrant. NaOH titrated with HBr titrant.

Formic acid titrated with ammonia (NH3) as a titrant

Explanation:

We have to look at something very critical here and that is, considering whether the acid/ base is strong or weak.

For a weak acid weak base titration, there is no suitable indicator neither is there any sharp pH range because no sharp change occurs. So, for a weak acid-weak base titration, there is only a very small change in pH at the equivalence point. This makes it impractical to carry out a weak acid- weak base titration.

Formic acid is a weak acid and ammonia is a weak base. Hence, Formic acid titrated with ammonia (NH3) as a titrant is a bad titration

idk what is it? is this a question that you know the answer or u dont
