what will haprn if ammonium chloride solution is used to standardize potassium tetraoxamaganate VII solution instead of ammonium iron II sulphate
H2SO4 is catalyst
H2SO4 + KMnO4 + FeSO4 = Fe2(SO4)3 + H2O + MnSO4 + K2SO
No idea
If ammonium chloride solution is used to standardize potassium tetraoxamaganate VII solution instead of ammonium iron II sulfate, it will lead to inaccurate results as these two compounds have different stoichiometries.
To explain further, standardization is the process of determining the exact concentration of a solution by reacting it with a known substance of known concentration. In this case, the known substance is ammonium iron II sulfate, which is commonly used to standardize potassium tetraoxamaganate VII solution.
Ammonium iron II sulfate, which has a chemical formula of (NH4)2Fe(SO4)2ยท6H2O, reacts with potassium tetraoxamaganate VII (KMnO4) in a 1:1 ratio. This means that one mole of ammonium iron II sulfate reacts with one mole of KMnO4.
On the other hand, ammonium chloride, with the chemical formula NH4Cl, does not react with KMnO4 in a 1:1 ratio. Therefore, using ammonium chloride instead of ammonium iron II sulfate will result in incorrect calculations of the concentration of the KMnO4 solution, as the stoichiometry of the reaction will not be balanced.
In summary, it is important to always use the correct standardized substance when determining the concentration of a solution. Using ammonium chloride instead of ammonium iron II sulfate will lead to inaccurate results and should be avoided.
