If you are titrating a base, using a weak acid as titrant would lead to the formation of a buffer as you added the weak acid. The weak acid would react with the base to form the salt of the weak acid + water, and this would buffer any changes in pH, thus making the titration meaningless.

Is CHOOH a weak acid or a weak base?
The formic acid is a weak acid.
Why is citric acid a weak acid?
Citric acid is considered to be a weak acid.
What combinations of compounds will make a buffer when mixed?
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
Is oxalic acid weak or strong?
Oxalic acid is a relatively strong weak acid. It has pKa1=1.27 and pKa2=4.28.
Why is H3PO4 not a buffer system?
H3PO4 is a weak acid, and a weak acid is not sufficient for a buffer.
Why sodium carbonate cann't be used as a primary standard in propanoic acid?
Sodiumj carbonate is a weak alakli and propanoic acid is a weak acid so you cannot use a weak acid and a weak alkali in an experiment as they wouldn't react properly. It would be difficult to find the indicator.
What is oxalic acid used for?
It is a weak acid mainly used for TITRATION
What is the name of the acid used to carbonate beverages?
Carbonic acid is a weak acid .This acid is used to carbonate beverages.
Explain of one strong and weak acid and give their uses?
strong acid- hydrochloric acid - used for digestion as a secretion of stomach weak acid- citric acid - used for maintaining salts in body
Which of the following is titrated using strong bases?
Titration is the controlled neutralisation of an acid and a base. If the titration is done using a weak acid and a strong base, it can be analysed in detail and all concentrations of the aqueous species at any volume addition of the titrant can be determined.
Indicators used in acid base titration?
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
Is CHOOH a weak acid or a weak base?
The formic acid is a weak acid.
Is H2CO3 a weak acid or strong?
H2CO3 Carbonic acid is a weak acid because it does not dissociate completely in solution making it a weak electrolyte.
Phosphoric acid is a strong acid?
Phosphoric acid 85% is the highest purity of this type of acid available in the market. Which is most used in food grade. Phosphoric acid is in the classification of weak acids.
How does titration of strong acid strong base differ from titration of weak acid strong base respect to quantity of base required to reach equivalent point?
There are three major differences between strong acid/strong base and weak acid/strong base titrations. For weak acid/strong base titrations: 1. The weak-acid solution has a higher initial pH. 2. The pH rises more rapidly at the start, but less rapidly near the equivalence point. 3. The pH at the equivalence point does not equal 7.00. (should be >7) In an acid-base titration, there is a 1:1 acid:base stoichiometry, so the equivalence point is the point where the moles of titrant added equals the moles of substance initially in the solution being titrated. Therefor the strength of the acid or base should not have an affect on the quantity of base required, only on the pH of the equivalence point. The number of moles of titrant and solution will have an effect on the quantity of base required.

Yes it is a weak acid
Acetic acid- strong acid or weak acid?
Weak.
