Oxalates are salts of oxalic acid containing oxalate ion. Oxalate ion is a dianion. Upon protonation, oxalate ion forms a commonly known compound, oxalic acid. The commonly known oxalate salts are sodium oxalate, potassium oxalate etc. The calcium metal ion reacts with oxalate ion to form an insoluble precipitate of calcium oxalate, which is the primary constituent of most of the common kind of Kidney stones.

The zinc oxalate is formed - ZnC2O4.
Copper oxalate is supposed to be a ribbon-like molecule where each copper 2+ ions are surrounded by four oxygen atoms in a square plan. These four oxygen atoms involve two oxalate anions. A copper II oxalate molecule can be described as an infinite ribbon of alternatively copper (Cu 2+) and oxalate (C2O4 2-) groups. Each copper 2+ cation is linked by two oxalate groups by weak electrostatic interactions with the four oxygen atoms.
It is a weak conductor. Its ions (oxalate ions and hydrogen ions) does not completely dissociates with water, so it does not serve as a good conductor. Some acids such as acids derived from metal containing ions generally completely dissociates, thus forming aqueous solutions that can conduct electricity.
oxalate
For example sodium oxalate has the chemical formula Na2C2O4.
The zinc oxalate is formed - ZnC2O4.
Sodium cation (Na+) and oxalate anion (C2O42-)
- sodium oxalate is an anti-clotting agent for blood - sodium oxalate can remove calcium ions from blood

It increases as it ripens. :D Now, that is what I wrote in my practical notebook. B-)

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.
