anion HC2O4−. A salt with this anion is sometimes called an acid oxalate‚ monobasic oxalate‚ or hydrogen oxalate. The equilibrium constant (Ka) for loss of the first proton is 5.37×10−2 (pKa = 1.27). The loss of the second proton‚ which yields the oxalate ion has an equilibrium constant of 5.25×10−5 (pKa = 4.28). These values imply that‚ in solutions with neutral pH‚ there is no oxalic acid‚ and only trace amounts of hydrogen oxalate.[1] The literature is often unclear on the distinction between H2C2O4

period of my assignment. INTRODUCTION GUAVA is a sweet juicy light or dark green coloured fruit. It is cultivated in all parts of INDIA. When ripe it acquires yellow colour and has a penetrating string scent. The fruit is rich in vitamin C and mineral. It is rich source of oxalate ion and its content in the fruit varies during different stages. Oxalate ion are extracted from the fruit by holding pulp with dilute H2SO4. The Oxalate ions are estimated volumetrically by titrating the solution

Guava (Psidium Guajava) is a genus of about 100 species of tropical shrubs and small trees in the myrtle family Myrtaceae. It is native in Mexico‚ as well Central America‚ Northern America and parts of the Carribeanbut not cultivated throughout the tropics. In Tagalog ‚ name bayabas are probably local renditions of guayaba. Numerous references in medical research identify guava as Psidium Guajava. Guavas (singular guava‚ /ˈɡwɑː.və/)[3] are plants in the Myrtle family (Myrtaceae) genus Psidium‚ which

Calcium oxalate (CaOx) being a major inorganic constituent of human kidney stones‚ contributes around 70-80% of the kidney stone. In India‚ approximately 5-7 million patients are suffering from kidney stone disease [6] (Kaladhar et al.‚ 2012). Urinary oxalate is found to be a major factor for calcium oxalate stone formation. As the molar ratio of oxalate-to-calcium is normally 1:10‚ slight changes in urinary oxalate concentration may cause crystallization and stone
