This is why: Ferrous ion, Fe++ is a reducer, by tending to being oxidized towards Fe+++
Cr in dichromate is +6 and by being reduced it becomes Cr+++ which is green
Ammonium sulphate and potassium nitrate do not react. All that will happen is that the solution will contain separate ammonium, sulphate, potassium, and nitrate ions dissolved in an aqueous (water) solution.
The formula for potassium sulfate is K2SO4, which indicates that each unit of the compound contains two potassium ions (K+) and one sulfate ion (SO4 2-).
Add the mixture in water ammonium chloride is highly soluble in water while Barium sulphate is insoluble , filter the solution the residue(solid part) is Barium sulphate, evaporate the solution and get solid Ammonium chloride.
Ammonium sulphate consists of two ions: ammonium (NH4+) and sulphate (SO4^2-).
Ammonium sulfate is most commonly called "fertilizer".
Potassium dichromate is better for titration with ferrous ammonium sulfate because it reacts with ferrous ions in a 1:6 ratio, making it easier to determine the equivalence point accurately. Potassium permanganate, on the other hand, reacts with ferrous ions in a 1:5 ratio, which can lead to less precise results and requires a more careful technique.
Ammonium sulphate and potassium nitrate do not react. All that will happen is that the solution will contain separate ammonium, sulphate, potassium, and nitrate ions dissolved in an aqueous (water) solution.
The titer volume of the sample gives the volume of Ferrous Ammonium Sulphate required to react with the excess potassium dichromate in the solution. Similarly, the titer volume for the blank (distilled water) gives the volume of Ferrous Ammonium Sulphate required to react with the excess potassium dichromate in the blank. The equation for the titration can be expressed as: Cr2O72 -- + FeSO4 (NH4)2SO4 = Cr+ + NH4+ + Fe 3+ From above equation it can be seen that one molecule of dichromate corresponds to one molecule of Mohr's salt. Thus, the difference in volume of excess K2Cr2O7 reacting with Mohr's solution can be calculated from the expression: = (Original vol. K2Cr2O7 -- vol. of K2Cr2O7 used for oxidation) solution - (Original vol. K2Cr2O7 -- vol. of K2Cr2O7 used for oxidation) blank = (Vol. of K2Cr2O7 used for oxidation) blank - Vol. of K2Cr2O7 used for oxidation) solution Hence, the difference in the titer volume for the solution and the blank is used to find out the Chemical Oxygen Demand directly.
The combination of haematoxylin and mordant is called Haematoxylin Lake. To form the haematoxylin lake, various metals like Ammonium alum (Ammonium ammonium sulphate), Aluminium potassium sulphate (potassium alum), or Aluminium sodium sulphate (sodium alum) etc are used.
The formula for potassium sulfate is K2SO4, which indicates that each unit of the compound contains two potassium ions (K+) and one sulfate ion (SO4 2-).
Add the mixture in water ammonium chloride is highly soluble in water while Barium sulphate is insoluble , filter the solution the residue(solid part) is Barium sulphate, evaporate the solution and get solid Ammonium chloride.
When potassium dichromate reacts with iron (II) sulfate in an acidic solution, a redox reaction occurs. The dichromate ions are reduced to chromium (III) ions, while iron (II) ions are oxidized to iron (III) ions. The overall reaction is 6Fe2+ + Cr2O72- + 14H+ -> 6Fe3+ + 2Cr3+ + 7H2O.
Ammonium sulphate consists of two ions: ammonium (NH4+) and sulphate (SO4^2-).
