how to find oxalate content in guava
As the guava fruit ripens, the amount of oxalate ion lessens as more of it is fixed into glucose and starches. This can be seen as the fruit sweetens and becomes less tart.
It increases as it ripens. :D Now, that is what I wrote in my practical notebook. B-)
Take 10 gms of fresh guava & crus it into a fine pulp using pestle-mortar. Transfer the pulp to a beaker and add 50ml of dil.H2SO4. Boil the contents for about 10 mins. Cool and filter the contents into a 100ml measuring cylinder. Make up the volume upto 100ml by adding distilled water. Tae 20ml of the solution in a titration flask and add 20ml of dil.H2SO4 to it. Heat te mixture to about 60C and titrate it against N/20 KMNO4 solution taken in the burette. End point: Appearance of pale pink color..... This should be done with different guavas at their different stages of ripening.
