What do you see when chlorine is added to a solution of bromide ions?
When chlorine is added to a solution of bromide ions, a red-brown color may appear due to the formation of bromine. This is because chlorine can oxidize bromide ions to bromine.
What reaction happens between bromine water and iron sulphate?
When bromine water is added to iron sulfate, the bromine oxidizes the iron(II) ions to iron(III) ions, forming a brown precipitate of iron(III) bromide. This reaction is a redox reaction, where the bromine is reduced and the iron is oxidized.
Result obtained when bromine is added to potassium chloride?
When bromine is added to potassium chloride, a redox reaction occurs. The bromine will oxidize the chloride ions, forming potassium bromide and elemental chlorine gas. The overall reaction can be represented as: 2KCl(aq) + Br2(l) -> 2KBr(aq) + Cl2(g).
What happens when aqueous bromide ions react with chlorine gas?
When aqueous bromide ions react with chlorine gas, bromide ions are oxidized to form bromine gas. This reaction typically occurs in the presence of an acid as a catalyst. The overall reaction can be represented by the equation: 2Br^-(aq) + Cl2(g) -> Br2(g) + 2Cl^-(aq)
What does KBr plus Cl2 yield?
When potassium bromide (KBr) reacts with chlorine gas (Cl2), it forms potassium chloride (KCl) and bromine (Br2). This reaction is a redox reaction, with bromide ions being oxidized to bromine gas and chlorine being reduced to chloride ions.

When chlorine is added to a solution of bromide ions, a red-brown color may appear due to the formation of bromine. This is because chlorine can oxidize bromide ions to bromine.
What happens in the reaction between chlorine gas and bromide ions?
In the reaction between chlorine gas and bromide ions, the chlorine gas oxidizes the bromide ions to form bromine gas and chloride ions. This is a redox reaction where chlorine undergoes reduction by gaining electrons from bromide ions.
Why chlorine displaces bromine from potassium bromide solution?
Fundamentally, because this reaction reduces the Gibbs free energy of the reactants when they are converted to products. Chlorine atoms have substantially greater electronegativity than bromine atoms, while chloride and bromide ions both have about the same, very low, electronegativity. Therefore, chemical potential energy is reduced by removing an electron from each bromide ion to form a bromine atom and transferring the electron so removed to chlorine atoms to form chloride ions instead of bromide ions.
What reaction happens between bromine water and iron sulphate?
When bromine water is added to iron sulfate, the bromine oxidizes the iron(II) ions to iron(III) ions, forming a brown precipitate of iron(III) bromide. This reaction is a redox reaction, where the bromine is reduced and the iron is oxidized.
What happens when aqueous bromine is added to sodium chloride?
When aqueous bromine is added to sodium chloride, bromine will displace chlorine to form sodium bromide and release chlorine gas. This reaction is a displacement reaction where a more reactive element, bromine, displaces a less reactive element, chlorine.
What happens when bromine is added to water?
When bromine is added to water, it reacts to form hypobromous acid (HBrO) and hydrobromic acid (HBr). This can further dissociate to form bromide ions (Br-) and hypobromite ions (OBr-). The overall reaction can be summarized as follows: Br2 + H2O → HBrO + HBr

When bromine is added to potassium chloride, a redox reaction occurs. The bromine will oxidize the chloride ions, forming potassium bromide and elemental chlorine gas. The overall reaction can be represented as: 2KCl(aq) + Br2(l) -> 2KBr(aq) + Cl2(g).
Why does the color of aqueous potassium bromide change when chlorine gas is bubbled into it?
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-

What do you get when you chemically combine chlorine gas and sodium?
It will be simple if you look at this in such way. Chlorine and bromine are strong enough oxidising agents to oxidise iron(II) ions to iron(III) ions. In the process, the chlorine is reduced to chloride ions; the bromine to bromide ions.
