b) Is iron going through oxidation or reduction?

c) How many of moles of electrons are transferred when Cr₂O₇^2- goes to Cr³⁺?

d) Is Chromium going through oxidation or reduction?

e)Write the balanced equation between potassium chromate and iron

f) How many moles of Cr₂O₇^2- are in 26.0mL?

g) What is the mole ratio between Fe²⁺ and Cr₂O₇^2-?

h) How many liters is 25.0mL

i) What is the molarity of Fe²⁺ from the titration?
