Role of phosphoric acid in dichrometry titration?
The phphoric acid is used to form stable complexes with Fe3+ ion
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.
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.
What is the reaction of phosphoric acid with nitric acid?
phosphoric acid

How can you calculate the concentration of a phosphoric acid solution from the titration with sodium hydroxide?
With a calculator. That is the easiest way.

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.

Is poly phosphoric acid different from phosphoric acid?
I don't think so.poly phosphoric acid and phosphoric acid have same moleculer structure.http://harvestchem.iblogger.org
What is the reaction of phosphoric acid with nitric acid?
phosphoric acid
What is H3PO4?
H3PO4 is the formula for phosphoric acid, also called orthophosphoric acid. For details see: http://en.wikipedia.org/wiki/Phosphoric_acid
What is the formula for H3PO4?
Phosphoric acid
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.
Is phosphoric acid stronger then citric acid?
i think it is phosphoric is stronger but I'm not sure?
