What happens when oxalic acid is heated?
Oxalic acid crystals are nothing but dehydrated oxalic acid (H2C2O4 . 2H2O). On heating, the water of crystallization is lost first. Then, the dehydrated oxalic acid decomposes into carbon dioxide(CO2), carbon monoxide(CO) and water(H2O).
How do you break down oxalic acid?
Cooking itself does release much of the oxalic acid, but adding calcium carbonate while cooking removes even more. The calcium carbonate combines to the oxalic acid and removes it from the food. Very little calcium carbonate is needed to make it effective. One tsp. per pot of water is plenty for these purposes.
Is oxalic acid harmful to humans?
