the standard solution in the above titration is citric acid because out of citric acid and naoh only citric acid can be obtained in purest frem while naoh is hygroscopic in nature
what is the procedure of determing the percentage of citric acid
It can find be out if citric acid forms a solution with water by adding citric acid to water and seeing if a clear solution is formed.
50% citric acid powder = 50 g citric acid/100 g 4% citric acid solution = 4 g citric acid/100 ml distilled water Determining how much citric acid powder to use is based upon how much citric acid solution you wish to make. To make 100 ml of solution, you should use 8 g of powder.
To deduce the concentration of a unknown solution from a known solution. Acid/base titration are common.
titration is a method by which a solution of known concentration is used to determine the unknown concentration of a second solution. Titration methods are based on reactions that are completed quickly such as the mixing of an acid and base.

Yes, in fact it is the only acknowledged acid (DIN, ASAC, NEN) to be used with standardisation in analytical titration chemistry (volumetrics > > titrimetrics > acidimetry). By the way, it is also used in oxidimetric standardisation.

a strong acid and a weak base.
Suppose you have titration solution do you know if you have too much standard base?
Vinegar is not the same thing as citric acid; vinegar is acetic acid. Acetic acid and citric acid are both weak acids, but citric acid is slightly more acidic.
I suppose that it is more simple to determine this value experimentally, by titration of a citric acid solution with a potassium hydroxide solution. However, if the material is pure, the theoretical Acid number is 876 mg KOH/g The Mwt of Citric acid is 192.12 and there are 3 Carboxylic acid groups per molecule. The acid number is defined as the number of milligrams of KOH per gram. So 192.12g requires 3 x 56.1 g KOH = 168.3g. So 168.3/192.12 = 0.876 g KOH/g and thus 876 mg KOH/g.
The concentration of sodium hydroxide in solution is determined by titration with an acid solution.
