Why bromine does not react with aqueous potassium chloride?

Bromine does not react with aqueous potassium chloride because it is less reactive than chlorine. Chlorine is more electronegative than bromine and hence has a higher tendency to displace bromine from its compounds. Consequently, bromine remains unreactive in the presence of aqueous potassium chloride.


What is the Reaction between fluorine and potassium bromide?

When fluorine reacts with potassium bromide, the fluorine displaces bromine from the compound to form potassium fluoride and bromine gas. This is a redox reaction where fluorine is reduced and bromine is oxidized.


What are examples of Inter-halogen compounds?

Examples of inter-halogen compounds are chlorine trifluoride (ClF3), iodine pentafluoride (IF5), and bromine chloride (BrCl). These compounds are formed by the combination of different halogen elements, such as chlorine, fluorine, iodine, and bromine.


What Element Would Be Least Reactive Out Of Chlorine Iodine Bromine And Fluorine?

Bromine would be the least reactive out of chlorine, iodine, bromine, and fluorine. It is a nonmetal halogen that has lower reactivity compared to fluorine, chlorine, and iodine.


If Bromine can displace iodine what can displace bromine?

Fluorine, and Chlorine can displace bromine from a compound.


What is the most reactive chlorine bromine fluorine and helium?

Fluorine is the most reactive element among chlorine, bromine, fluorine, and helium. It has the highest electronegativity and readily forms compounds with other elements. Helium, on the other hand, is the least reactive noble gas due to its stable electron configuration.


Which element has the smallest atomic radius fluorine chlorine bromine iodine astatine?

Fluorine has the smallest atomic radius among fluorine, chlorine, bromine, iodine, and astatine.


Is fluorine Chlorine and bromine metals?

true


What react with potassium?

all of the halogens: bromine, fluorine, oxygen, chlorine and iodine. and it is highly reactive with water.


What are three elements that have properties similar to chlorine?

Fluorine: Like chlorine, fluorine is a halogen with similar chemical reactivity and electronegativity. Bromine: Bromine is another halogen that shares some properties with chlorine, such as being a strong oxidizing agent. Iodine: This halogen has similarities to chlorine in terms of chemical reactivity and forming compounds with similar structures.


Why are bromine iodine chlorine and fluorine grouped together?

Bromine, iodine, chlorine, and fluorine are all halogens, which are a group of elements on the periodic table with similar chemical properties. They all have seven valence electrons and readily form compounds with other elements. Their reactivity increases as you move up the group from fluorine to iodine.


Which element is a member of the halogens family?

flourine, chlorine, iodine, bromine, astatine
