Hello budding chemists,
I was wondering whether i could get some assistance with this qsn. I'm not to sure how to write the second equation, where i must include the Fe
2O
3.
How do i do the decompostition? Help would be greatly appreciated.
A 50.00mL solution with Iron(III) Nitrate has excess NaOH solution added to it, to precipitate Fe(OH)3
After heating, it decomposes to Fe2O3. The mass of precipitate is 0.533g. Calculate the iron concentration in the original solution.
Answer: 0.133MHere is the equation that i came up with:
Fe(NO
3)
3 (aq) + 3NaOH (aq)
3NaNO
3 (aq) + Fe(OH)
