Why is a back titration sometimes used for an analysis rather than a direct titration?
Back titrations are used when a reaction occurring in the conical flask can not be detected using an indicator such as phenolphthalein. So, after this titration has been performed, the 'excess' is then titrated with something that can be detected more easily using phenolphthalein etc.
Why you cant coat iron on gold?
Actually it can be done, though why you would want to is another question. Iron can be deposited onto Gold using electroplating in a bath of Ferrous Sulphate with Sodium Gluconate.
What happens when you combine sulfuric acid and iron?
Let's see. Using the 2 oxidation state of iron. Fe + H2SO4 -> FeSO4 + H2 Ferrous sulphate and hydrogen gas are produced by this reaction.
What is the name for Fe2O3 using the Stock system?
-There are elements three elements in the compound and 6 atoms all together. -Iron(1)+Sulphur(1)+Oxygen(4)=Iron Sulphate. -Fe:Iron+S:Sulphur+O:Oxygen=FeSO4:Iron Sulphate. -It is Iron Sulfate if you are an American but for British it is Iron Sulphate.
What is the advantage of using an aliquot for titration?

What is the purpose for using phenolphthalein for an acid base titration?
It's the colour indicator you watch for during the titration.
Ferrous oxalate reaction with potassium permanganate?
Potassium permangante, being a very strong oxidizing agent, oxidizes both the Fe2+ ion and the oxalate ion. Redox reactions are shown below: Oxalate oxidation: 2MnO4- + 16H+ + 5C2O42- ---> 2Mn2+ + 8H2O + 10CO2 Iron(II) oxidation: MnO4- + 8H+ + 5Fe2+ ---> Mn2+ + 4H2O + 5Fe3+ Moreover, if one needs to determine the exact percentage of oxalate and ferrous ions in solution, a titration is carried out using the permanganate, which will react with both the oxalate and ferrous ions. But, the carbon dioxide is liberated from the soution now, and zinc is added whch reduces the Iron(III) back to Iron(II). Another titration is then carried out using the permanganate, which gives a reading for the Iron(II) in solution only.
What is the advantage of using indicator rather than using thermometer to detect the end point of an acid base titration?
At the endpoint of an acidimetric titration there is no temperature change at all, so a thermometer won't indicate that.You'd better use the color change of a proper indicator when the pH changes at the end point. The only advantage is that it works well!
