A titration may be done on any reactive pair of compounds where a balanced equation is known and concentration information on one of the compounds is available. Below is an example of a titration with a Redox reaction between permanganate and iron(II). 1.5203 grams of potassium permanganate (a primary standard) was dissolved in enough water to make 500.0 mL of solution. a. What is molarity of the potassium permanganate solution? b. This permanganate solution is used as a standard to titrate a compound known to known contain iron(II) according to the following net ionic equation: MnO4 + 8H+ + 5Fe²+ Mn²+ + 4H₂O + 5Fe³+ It required 41.10 mL of the permanganate solution to titrate 1.5495 grams of the compound. Identify the iron(II)-containing compound from the list below: ● FeCl₂-4H₂O • Fe(C₂O4)2 2H₂O Fe(NH4)2(SO4)2 6H₂O ● FeSO4.7H₂O

doesn't change anything or compromise the data
6. A titration may be done on any reactive pair of compounds where a balanced equation is known
and concentration information on one of the compounds is available. Below is an example of a
titration with a Redox reaction between permanganate and iron(II).
1.5203 grams of potassium permanganate (a primary standard) was dissolved in enough water
to make 500.0 mL of solution.
a. What is molarity of the potassium permanganate solution?
b.
This permanganate solution is used as a standard to titrate a compound known to
known contain iron(II) according to the following net ionic equation:
MnO4 + 8H* + 5Fe²+ Mn²+ + 4H₂O + 5Fe³+
It required 41.10 mL of the permanganate solution to titrate 1.5495 grams of the
compound. Identify the iron(II)-containing compound from the list below:
●
FeCl₂ 4H₂O
FeSO4.7H₂O
20
●
Fe(C₂O4)2.2H₂O
Fe(NH4)2(SO4)2 6H₂O
