Why does a cola soft drink need to be decarbonated to perform a phosphoric acid titration?
Because carbon dioxide in water is a mild acid and will react with the sodium hydroxide making accurate titration impossible.
Why is ortho phosphoric acid used in titration?
Phosphoric acid is used in titraions involving Iron(III) ion. Ferric ions are not stable in aqueous medium. It forms a stable complex with phosphate ions.
How much acid is in Dr. Pepper?
There is about 0.32% phosphoric acid in diet cola. I just did an experiment and those were my results using NaOH in a titration.
Why you use phosphoric acid during permanganometry titration?
Phosphoric acid is used because it tends to lessen any interfering colour changes. Also due to the presence of phosphoric acid ( the phosphate complex of Fe 3+ is colourless , so the yellow colouration of Fe 3+ ions does not disturb the end point detection.
