How does potassium permanganate react with Fe2+ ions?

The purple potassium permanganate solution reacts according to the following half equation and changes to colourless Mn2+ solution. – is reduced. Fe2+ loses one electron. The oxidation number of Fe2+ increases when it is oxidised to Fe3+.

What is the Colour change at the endpoint of the titration of iron LL sulfate with potassium manganate VII )?

the colour change which occurs is purple to colourless, because of the decreased concentration of permanganate ions.

What happens when ferrous salt is treated with permanganate ion in acidic medium?

So, the reaction between Mohr’s salt and potassium permanganate is a redox reaction. In this redox reaction, ferrous ion from Mohr’s salt gets oxidised and pink coloured of manganese present in potassium permanganate, which is in the +7 oxidation state gets reduced to colourless Mn2+ state.

How does acidic potassium permanganate react with ferrous?

When potassium permanganate is added to the acidulated solution of ferrous sulphate, ferrous ion is oxidised and the acid is neutralised. Therefore, the correct options are (C) and (D). Note : Oxidation numbers represent the potential charge present on an atom in its ionic form.

How does the acidified permanganate solution react with Fe2+?

(i) Acidified KMnO4 solution oxidizes Fe (II) ions to Fe (III) ions i.e., ferrous ions to ferric ions.

How does acidic permanganate react with ferrous sulphate and so2?

When ferrous sulpahte is added to acidic potassium permanganate slowly the purple colour fades away because acidic potassium permanganate is an oxidising agent and it converts ferrous ions into ferric, while the purple permanganate changes to colourless manganese sulphate.

What is the colour change at the end point in the estimation of ferrous and ferric iron?

The addition of orthophosphoric acid is to reduce the redox potential of the ferrous to ferric iron and to obtain the sharp change of the end point of titration from a colourless to a permanent violet blue colour solution.

Why KMnO4 is used in acidic medium?

It has the ability to oxidize the acids to alcohols. It acts as an oxidizing agent in both acidic medium and basic medium.

Is KMnO4 unstable in acidic medium?

Its solution is unstable in acidic medium.

What happens when acidified potassium permanganate solution reacts with ferrous sulphate solution write balanced chemical equations?

2KMnO4+8H2SO4+10FeSO4→K2SO4+2MnSO4+5Fe2(SO4)3+8H2O.
