What criterion is used in selecting an indicator for a particular acid-base titration?
the factors are - 1. the kind of titration ie strong acid -strong base,strong acid -weak base,weak acid-strong base,weakacid -weak base. 2.the endpoint 3. the rate of rxn
Will the solution at the end point of an acidbase titration be acidic neutral or alkaline if it is a weak acid and strong base?
alkaline obviously! strong acid + strong base= neutral strong acid + weak base= acidic weak acid + strong base= alkaline
A titration of an acid and base to the equivalence point results in a noticeably acidic solution It is likely this titration involves?
a strong acid and a weak base.
What will be the pH at the equivalence point of the titration in question 3?
For strong acid/strong base reactions: pH 7 is the equivalence point For titration of a weak base with strong acid : pH 6-3 is the equivalence point For titration of a weak acid with strong base : pH 8-11 is the equivalence point For weak acid/weak base reactions it is also around pH 7, but it happens so NON-sharply, vague, that titrations can't be used for these.
What is phenolphthalein used in titration labs?
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.

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.
Which indicator is used for the titration of weak acid and strong base?
Phenopthalene is used commonly
Which indicator is used in titration for strong acid?
It depends on the 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.
Where is the buffer region in a titration curve for the titration of a weak acid with a strong base?
It is the nearly horizontal region before the equivalence point.
What are the best indicator use in titration of weak base against strong acid?
vodka cruisers, the raspberry one.
Standardising HCl using Na2CO3 titration. textbook says the solution at the equivalence point is slightly acidic. is it and why?
it depends on the strength of the acid and base used: so, strong acid + strong base = neutral equivalence point strong acid + weak base = acidic equivalence point weak acid + strong base = basic equivalence point In this case, HCl is a strong acid, and Na2CO3 a weak base. Therefore, the equivalence point will be slightly acidic.
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.
