Ferrous sulfate is an iron salt that is also known as green vitriol. Ferrous Sulfate signifies a variety of salts with the formula FeSO4 ⋅ xH2O. The Other names of Iron (II) sulphate include; Ferrous sulfate, Green vitriol, Iron vitriol, Copperas, Melanterite, Szomolnokite. Blue-green heptahydrate (hydrate with “7” water molecules) is the ...
2g of ferrous sulphate crystals are heated in a dry boiling tube. (i) List any two observations. (ii) Name the type of chemical reaction taking place. (iii) Write the chemical equation for the reaction.
When zinc is added to solution of Iron (II) sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, therefore it displaces iron from it's solution of iron sulphate and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.

3.92 g / L of a sample of ferrous ammonium sulphate (F e S O 4. ( N H 4 ) 2 S O 4 . 6 H 2 O ) reacts completely with 50 m L N 10 K M n O 4 solution. The percentage purity of the sample is :
Iron being more reactive than copper will displace copper from its salt and form a subsequent salt of ferrous sulphate. During the reaction, the colour of copper sulphate [blue] will change to greenish-blue {ferrous sulphate}. This is an example of a
When sodium hydroxide solution is added to a freshly prepared solution of ferrous sulphate, a green precipitate of ferrous hydroxide is formed which on standing turns brown because: ferric salts are unstable the mixture becomes dirty ferrous hydroxide becomes
2019年12月30日 · • Test tube 2 contains pieces of zinc mixed with ferrous sulphate solution, and test tube 3 contains pieces of aluminum mixed with ferrous sulphate solution. • Both zinc and aluminum are more reactive than iron as they are placed above iron in the reactivity series of metals.
Correct option is B. Decomposition and redox $$\bullet$$ Strong heating of ferrous sulphate $$(FeSO_4)$$ leads to the formation of a brown solid ferric oxide $$(Fe_2O_3)$$ and two gases, sulphur dioxide $$(SO_2)$$ and sulphur trioxide $$(SO_3)$$ are formed. ...
Q 3. Stannous sulphate (S n S O 4) and potassium permanganate (K M n O 4) are used as oxidising agents in acidic medium for oxidation of ferrous ammonium sulphate to ferric sulphate. The ratio of number of moles of stannous sulphate required per mole of ferrous ammonium sulphate to the number of moles of K M n O 4 required per mole of ferrous ...
