What is the function of the phenanthroline solution that is added to the unknown iron?
phenanthroline is used as a redox indicator
Why was an acid added to the iron II ammonium solution before titration?
To create an acidic medium or in another word made iron (II) ammonium solution more acidic as kmno4 acts as a strong reducing agent only in acid medium.
Why iron does not displace sodium from salt solution?
Iron does not displace sodium from a salt solution because it is not reactive enough. Iron does, however, displace Cu from a copper sulphate solution.
What will happen when iron and iron react?
Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.
What will happen when zinc is added to iron filling?
You will have a mixture of zinc and iron filings.
What is the function of the phenanthroline solution that is added to the unknown iron solution?
phenanthroline is used as a redox indicator
What is the function of the phenanthroline solution that is added to the unknown iron?
phenanthroline is used as a redox indicator
What is the purpose of the hydroxylamine solution that is added to the unknown solution in the iron analysis?
hydroxylamine is a reagent that helps reduce iron
What would happen if you added iron to a solution of magnesium sulphate?
No Reaction
Is iron is an indicator?
its an indicator
What happens when iron oxide is added to sodium hydroxide solution?
anything important
Why colour of copper sulphate solution changes to light green when iron filings are added?
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
What happens when iron nail is added to zinc sulphate solution?
No reaction will take place as iron is less reactive than zinc.
The indicator lamp in a dry iron comes on when the is plugged in but the iron does not heat up this is an indicator that the?
If the indicator lamp in a dry iron comes on when the iron is plugged into the power socket, but the iron does not heat up, it indicates that your iron has a problem with one of its electrical components.
What happens when a piece of copper is added to iron II chloride solution?
I think it turns from brown to a silver color
What will happen when you add iron fillings to a solution of mercuric nitrate?
Drops of liquid metallic mercury will form and drop to the bottom of the solution: Iron is higher in the electromotive series than mercury and will therefore displace mercury from compounds of mercury, the iron being changed to cations that replace as many of the mercury cations in the solution as is stoichiometrically possible, based on the amount of iron added to the solution and the amount of mercuric nitrate originally present.
Why does iron filings in copper sulphate solution become colourless from green after sometime?
Copper sulfate solution starts of a blue colour. When Iron metal is added to the solution a REDOX reaction begins in which the copper is reduced (gains electrons) to become copper metal and the iron is oxidised (loses electrons) to become iron ions. When the iron ions go into solution, it will change to a green colour which is the colour of iron (II) sulfate. As a general principle, a more reactive metal will displace a less reactive metal from solution by the process described above.
