2KI+Br2 ---->2KBr +I2
Potassium and bromine form the ionic compound potassium bromide with the chemical formula KBr.
When chlorine gas reacts with potassium bromide, the chlorine will displace bromine in the compound forming potassium chloride and bromine gas. The color of the mixture will change from colorless to reddish-brown due to the formation of bromine gas.
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.
Yes, its negative ion is called Bromide = Br-
When naming a compound containing potassium and chlorine, you change the suffix of the anion name to "-ide." In the case of potassium and chlorine forming KCl, the compound is named potassium chloride.
Potassium and bromine form the ionic compound potassium bromide with the chemical formula KBr.
When chlorine gas reacts with potassium bromide, the chlorine will displace bromine in the compound forming potassium chloride and bromine gas. The color of the mixture will change from colorless to reddish-brown due to the formation of bromine gas.
not by sharing its electron but by "giving" it to the bromine ion so it has a full outer shell of electrons. Ionic bonding.
When potassium iodide is added to a solution of bromine, a reaction occurs forming potassium bromide and iodine. The iodine produced in the reaction is responsible for the color change in the solution from orange to brown/black.
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).
Potassium and bromine will form an ionic bond. Potassium will donate an electron to bromine, forming K+ and Br- ions that will be attracted to each other due to their opposite charges.

Bromine is a molecular compound Br2 and the intermolecular forces are london dispersion forces. Potassium chloride is an ionic compound forming a lattice with strong electrostatic forces holding the lattice together. Less thermal energy is required to shake solid Br2 apart than that required for KCl
Elements that can bond with bromine include metals such as sodium, potassium, and magnesium, forming ionic compounds. Nonmetals like hydrogen, carbon, oxygen, and nitrogen can also bond with bromine to form covalent compounds.
Yes, its negative ion is called Bromide = Br-
It is a base forming salt, very soluble (as all potassium salts are)
Potassium will lose 1 electron to form a 1+ ion.
