Question

While practicing in the laboratory, you have some yellow spot of $$FeCl_3$$ on your white shirt. Those yellow spots can be removed by complexing $$Fe^{3+}$$ by oxalate ion and washing it with water.  $$Fe^{3+}+3C_2O^{2-}_4\rightarrow \underset{colourless(soluble)}{ [Fe(C_2O_4)_3]^{3-}}$$
If true enter 1, else enter 0.


Solution

While practicing in the laboratory, if we have some yellow spot of $$FeCl_3$$ on our white shirt. 
Those yellow spots can be removed by complexing $$Fe^{3+}$$ by oxalate ion and washing it with water.
