Presence of oxalate ion in guava fruit during different stages of ripening?calculation and observations

Dear student,

u take guava extract (properly measured) and titrate it with any base for eg sodium hydroxide (naoh) using a burette. u obtain the amount of naoh used in neutralizing that fixed amount of guava extract. use the common mole and molarity concept. once u find our the molarity of the guava extract, multiply with the molar mass of oxalic acid...u will get the strength.
