Why potassium dichromate solution changes to green colour when it is added to ferrous ammonium sulphate solution?

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

What is the equation when ammonium sulphate react with potassium nitrate Will it store for commercial purpose?
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.
Potassium sulphate formula?
The formula unit for potassium sulphate is K2SO4.
How do you separate ammonium chloride and barium sulphate?
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.
What is the difference between potassium chloride and potassium nitrate?
The difference between potassium nitrate and potassium sulphate is that the potassium nitrate is superior to potassium sulphate. The potassium nitrate has high solubility while the potassium sulphate has moderate solubility.
Is ammonium sulphate a base or acid?
Ammonium sulfate is a neutral salt which shows alkaline behavior in solution due to the hydrolysis of the ammonium ion.
Which one is better for titration with Ferrous Ammonium Sulphate potassium dichromate or potassium permaganate and why?
potassium dichromate

What is principle of potassium dichromate in COD estimation?
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.
Do Ammonium Sulfate and Potassium chloride react?
pottasium sulphate and ammonium chloride as a mother liqour
What is a hematoxylin lake?
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.
How do you separate ammonium chloride and barium sulphate?
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.
What is the composition of fehling's solution?
Fehling's solution A= concentrated aqueous solution of Copper (II) sulphate, Fehling's solution B= solution of Sodium-potassium tarterate + sodium hydroxide.
What is the difference between potassium chloride and potassium nitrate?
The difference between potassium nitrate and potassium sulphate is that the potassium nitrate is superior to potassium sulphate. The potassium nitrate has high solubility while the potassium sulphate has moderate solubility.
Is ammonium sulphate a base or acid?
Ammonium sulfate is a neutral salt which shows alkaline behavior in solution due to the hydrolysis of the ammonium ion.
How many grams per liter ammonium sulfate are in a saturated solution of ammonium sulfate?
744 g/L of ammonium sulphate, at 20 0C
How can you prepare ferrous sulphate ammonium sulphate solution?
You have to dissolve this in an amount of water and stirr it gently. It is a very well soluble salt.
