Chlorine is a more reactive halogen than bromine, therefore, when chlorine gas is bubbled through a calcium bromide solution, the chlorine will take the place of the bromine. This is called an anionic single replacement (displacement) reaction.

Cl2(g) + CaBr2(aq) --> Br2(l) + CaCl2(aq)

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-


If chlorine gas is bubbled through an aqueous solution of sodium iodide the result is elemental iodine and aqueous sodium chloride solution what kind of reaction took place?

The reaction is a redox reaction where chlorine is reduced to chloride ions and iodide ions are oxidized to elemental iodine. Overall, it is a displacement reaction where chlorine displaces iodine from sodium iodide to form sodium chloride and elemental iodine.


Chlorine gas is bubbled through a solution of distilled water?

When chlorine gas is bubbled through a solution of distilled water, it reacts with water to form a mixture of hydrochloric acid (HCl) and hypochlorous acid (HOCl). This can lead to the formation of a weak solution of hydrochloric acid along with a small amount of hypochlorous acid, which can further react to produce hypochlorite ions (OCl-).


Chlorine and potassium iodide?

As a stronger oxidizing agent than Iodine, Chlorine oxidizes the Iodide ions to Elementary Iodine, while itself gets reduced to Chloride. The equation for this reaction is:Cl2 + 2 I- ----> 2 Cl- + I2


What happens when chlorine gas is added to potassium iodide solution?

When chlorine gas is bubbled into an aqueous solution of potassium iodide, some of the iodide ions are oxidized to iodine. The iodine molecules combine with iodide ions to form brown triiodide ion, I3-. In this demonstration, the aqueous solution is above a layer of carbon tetrachloride, in which iodine is quite soluble. The beautiful violet color of iodine can be seen as the iodine dissolves in the carbon tetrachloride layer. With excess chlorine, iodine reacts to form iodine monochloride, ICl, which is ruby red. The iodine monochloride reacts further to form iodine trichloride, ICl3, which is much lighter in color, causing the solution to be decolorized.

What is the formula to make chlorine dioxide?

To make chlorine dioxide, you can mix sodium chlorite (NaClO2) with an acid such as hydrochloric acid (HCl) or sulfuric acid (H2SO4). The reaction forms chlorine dioxide gas, which can be bubbled through water to produce a solution of chlorine dioxide. The chemical equation for the reaction is 5NaClO2 + 4HCl → 4ClO2 + 5NaCl + 2H2O.
