Iron(II) can be oxidized to iron(III) by dichromate ion, which is reduced to chromium(III) in acid solution. A 2.5000-g sample of iron ore is dissolved and the iron converted into iron(II). Exactly 19.17 $\mathrm {mL}$ of 0.0100 $M$ $\mathrm{Na}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}$ is required in the titration. What percentage of the ore sample was iron?

the most common or off irony are he might on Mad Night, and they can be reduced to the pure irony from their old by using the reducing agents such as I Need to See Her to seven or either by heating goes with carbon. Inform off Cook for the question. Considering the reactions here, the weight off island is 2.500 graham, while the volume is 0.1 em off a NATO CR two or seven. From this, the weight off island present in the old is calculated by the title ation off Iron Bed dyke Remit solution. So the moon's off crewmates CR two or seven too negative requires to convert Effy to positive in tow. F it three positive. According to the provided reaction, one more off Seattle or seven reacts with six moral off. I didn't do positive substituting in the values 1.150 into 10 days to put three moles off. A few too positive will react with 19.71 19.17 in 10 days to par five more lof CR two or seven. So the total mass off island present will be 0.0 642 drums and the percentage will be 2.57 bosom
