Nitric acid being an oxidizing reagent help the oxidation of Fe(II) to Fe(III).
The molar mass of Fe2(SO4)3 is 399,88 g (anhydrous).
You can obtain the ferric sulphate - Fe2(SO4)3; because the ferrous sulphate react as a reducing agent.
The KIA medium has an iron salt-ferric ammonium citrate- and sodium thio sulfate. The ferric ions bind with the hydrogen sulfide to then form ferrous sulfide, which gives off a black percipitate that can be seen on the media.
Ferric = Iron(III) = Fe3+
Ferric ions exist in solutions.
first dissolve in sulfuric acid and then add water
dissolve 40 grams of ferric ammonium sulphate in 100ml distilled water and add few drops of 6N nitric acid
I think neutral ferric chloride is prepared by mixing iron(III) chloride with ammonium hydroxide.
ferric hydroxide + citric acid ---> product A (ferric citrate)Product A + ammonia solution --> ammonium ferric citratecheck out for stoichiometric equation
how can i prepare ferric ammonium citrate redish crystals
Ferric sulphate, or iron (III) sulphate has the formula Fe2(SO4)3.
Solid ferric hydroxide, Fe(OH)3, precipitates out of solution. The resulting sodium sulphate remains dissolved.
oxalate
Fe2(SO4)3
Fe2(SO4)3
The colour depends on the degree of hydration, but it is most often green.
The Ferrous ion has a '2+' charge. Hence the formula for ferrous sulphate is FeSO4. NB The Ferric ion has a '3+' charge. Hence the formula for ferric sulphate is Fe2(SO4)3
