what toxic gas is given off when oxalic acid is heated ?
Sulfuric acid, as it disassociates almost 100% in solution.
(cooh)2 + hcooh + co2

These acids doesn't react; they are only mixed.
Sulfuric acid, as it disassociates almost 100% in solution.
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
To act as a catalyst
(cooh)2 + hcooh + co2
Rhubarb leaves contain oxalic acid. So too does the stem itself. Tomatoes also contain oxalic acid, especially the leaves. Oxalic acid is a poison. Oxalic acid is also found in potatoes and in peppers as well as in peas. Oxalic acid becomes concentrated in tomato paste. In the tomato, red tomato's have less oxalic acid than do green tomato's.
The oxalic acid is heated to icrease the rate of reaction which is very slow at room temperature
C2O4H2+H2SO4+5O=CO2+H2+SO4 Balance it by yourself if you can!
