Looking for an analytical method for Citric Acid

1999. A. Analysis of citric acid is a simple titration with sodium hydroxide. I don't remember the exact sample size, sodium hydroxide normality, and indicator, but phenolphthalein should do the trick. Make a standard from a known amount of powder in water if you aren't sure of the calculation factor.

Acid

An aqueous solution of sodium hydroxide, NaOH(aq), is a strong base. The pH at the equivalence point of a weak acid-weak base titration would depend on the relative weakness of the acids and bases used. If the weak acid is a stronger electrolyte than the weak base, the solution will be acidic, if the weak base is a stronger electrolyte than

How to Make a Citric Acid Buffer Solution

Apr 11, 2018A citric acid buffer works in the same way as a sodium citrate buffer. To make this, you need both citric acid and the conjugate base, sodium citrate. Citric acid is a weak organic acid that occurs naturally in citrus fruits and can efficiently maintain a pH from 3 to 6.2. Sodium citrate is the sodium salt of citric acid., with alkanizing activity.
