What indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
Litmus paper
What is the action of sodium hydroxide on the colour of phenolphthalein?
Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
Echnch Rome Blue Black T an indicator in EDTA titration?
eriochrome black T is an indicator for EDTA titration
Why it is necessary to cap the buret and minimize the CO 2 absorption from the NaOH solution. How will this affect your results?
When sodium hydroxide absorb carbon dioxide sodium carbonate is formed. But we need a defined mass (volume) of NaOH for a titration.
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein, because NaOH is a strong base.
What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?
Methyl orange acts as a pH indicator in the process of sodium carbonate and hydrogen chloride titration. The addition of methyl orange will indicate the ratio of sodium carbonate to hydrogen chloride by the colour which develops.

What is a real life example of a titration?
Titrations are used in the manufacture of tablets, an example is, dilute sulphuric acid, phenolpthaline indicator and sodium hydroxide!
Is the indicator generally added to the titrant or analyte in a titration?
Analyte is the indicator that is generally added in titration.
Is the indicator generally added to the titrant or the analyte in titration?
Analyte is the indicator that is generally added in titration.

eriochrome black T is an indicator for EDTA titration
Why nitric acid is used in volhard method?
The titration must be done in acidic medium to prevent the precipitate of Iron(III) as hydrated oxide (iron hydroxide). Iron (III) is an indicator.
What is the function of an indicator in titration?
Change color
