Answer:
... Therefore, pickling treatments employing acids, such as HCl, HNO 3 , and oxalic acid, were required to wash off the nonframework Al species. Giudici et al. 22 observed that oxalic acid, a stronger dealumination agent than HNO 3 , exerted a greater effect on the framework structure than HNO 3 ; it mainly removed the nonframework Al and increased the B/L ratio. However, oxalic acid removed the nonframework Al and extracted a part of the Al framework because of its
Answer:
Oxalic acid is an organic acidic compound having the chemical formula H2C2O4. This compound exists as a colourless solid that can easily dissolve in water. This acidic compound is a dicarboxylic acid because it is formed from the combination of two carboxylic acid groups; in fact, it is the simplest dicarboxylic acid. Furthermore, it has a high acid strength, and we can name it as a strong reducing agent. The conjugate base of oxalic acid is an oxalate ion. Generally, oxalic acid occurs in the dihydrate form, and it naturally occurs in some food. The molar mass of the anhydrous form of this acidic compound is 90 g/mol.
And on the other hand
Citric acid is a weak organic acid having the chemical formula C6H8O7. It occurs naturally in citrus fruits. There are many applications of this compound. Therefore, manufacturers tend to produce a high amount of citric acid annually. Some of the important applications include use as an acidifier, as a flavouring, and as a chelating agent. There are two forms of this acid as the anhydrous form and the monohydrated form.
The anhydrous form of citric acid is the water-free form. It appears as a colourless substance and is odourless as well. There is no water in its dry, granulated form. We can produce this compound via crystallization from hot water.
The anhydrous citric acid is formed from the monohydrate form at 78 °C. The density of the anhydrous form is 1.665 g/cm3. It melts at 156 °C, and the boiling point of this compound is 310 °C. The chemical formula of this compound is C6H8O7, while the molar mass is 192.12 g/mol.
