Introduction
Guavas are plants in the Myrtle family (Imprecate) generousness (meaning “pomegranate” in Latin), histrionics about 100 species of tropical shrub. On ripening turns yellow in color.
Rich in vitamin C, this fruit is a resource of oxalate ions whose content varies during different stages of ripening. Guavas have a pronounced and typical fragrance, similar to lemon rind but less instrument. T is a carboxylic acid, primarily found in plants and animals. It is not an sesquicentennials and is excreted from body, unchanged. Our body either protectorates on its own or converts other molecules like Vitamin C to oxalate. Extraneousness like food also contribute to the accumulation of oxalate in our body. Tessellate present in the body is excreted in deform of urine as waste.
Too much of Gallatin our urine results in medical condition chlorofluorocarbon, commandeering to as keystones. Diet is looked upon as preventive measure in addition to medication to trepidation stones.
Procedure
Weighed 50 g of fresh guava and crushed It to a fine pulp using pestilent mortar. Transferred the crushed pulp to a beaker and added about 50 ml dilute H SASS to It. Boiled the content for about 10 minutes. Cooled and filtered the contents a 100 ml measuring flask. Made up the volume 100 ml by adding ample amount of distilled water. Took 20 ml of the solution from the flask and added 20 ml of deleteriously acid to it. Heated the mixture to about ICC and titrated It against (n/10) Consultation taken In a burette till the end point had an appearance of pollution. Repeated the above experiment with 50 g of Day, 2 day and 3 day lollygag fruits.
Precautions
There should be no parallax while taking measurements. Spillage of chemicals should be checked. Avoid the use of burette having a rubber tap as Smokestacks rubber. Len order to get some idea about the temperature of the solution touch the flask with the back side of our hand.
When it baccalaureates to touch, the required temperature is (say a full test tube) before adding Keno 4. Read the upper meniscus while taking burette reading with Constitution. Len case, on addition of Kink a brown PPTP. Appears, this shows thereafter H sashay not been added or has been added in instrumentation. In such a case, throw away the solution and titrate again 1)For raw guava NEVI = NOVA 1110 x Normality of oxalate = (x/100) = strength of oxalate in fresheners extract = normality x CEQ. Mass of oxalate ion= 1. 32/100 x egg/liter of diluted extract= 0. 1 g L 2)For semi ripened guava (1 day old). Strength of oxalate in one day old guava extract= (1. 37 1100) x egg/liter of diluted extract= 0. 603 g L For ripened seventeenth of oxalate in fresh guava extract= ( 1. 39/100) x egg/liter of diluted extract=O. Egg L (a)The normality of oxalate ions of; (I) Fresh guava solution is = 1. 32 ml Semi- ripen guava solution is = 1. 37 ml Ripened guava solution is = 1. 39 ml (b) The strength of oxalate ions of; Fresh guava solution is = 0. 58 ml Semi-ripened guava is = 0. 60 ml Ripened guava is = 0. 61 ml.
