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.
Universal indicator will change to a bleaching effect color (yellow or yellow-green) when chlorine water is added due to the presence of hypochlorous acid.
The chemical and physical properties are changed.
When chlorine solution is added to sodium astatide solution, a chemical reaction may occur where the chlorine displaces the astatine in the compound, forming sodium chloride and releasing free astatine. This reaction is generally not advisable due to the hazardous nature of astatine and the potential formation of toxic compounds.
The dark red-brown color change occurs because the chlorine oxidizes iodide ions to form iodine, which reacts with excess iodide ions to form triiodide ions. These triiodide ions absorb light in the visible range, resulting in the dark red-brown color observed in the solution.
When chlorine is added to a solution containing bromine ions, the chlorine will react with the bromine ions to form a mixture of chlorine and bromine compounds, such as bromine chloride. This reaction is a redox reaction where chlorine is reduced and bromine is oxidized.
Carbon dioxide gas is produced when hydrochloric acid solution is added to sodium carbonate.
How much acid and chlorine should be added to a 5000 liter to make 5 ppm solution
Add KMnO4 (Potassium Permanganate) which is a purple solution. If it is added to an alkene or alkyne it will turn colourless and produces a brown precipitate.
The indicator that has no color at all is a colorless indicator, such as phenolphthalein in its neutral pH state.
When chlorine is added to sodium bromide solution, bromine is produced as one of the products through a redox reaction. The chlorine oxidizes the bromide ion to form bromine gas, while itself being reduced. This reaction is used to synthesize bromine from sodium bromide.
When chlorine gas is added to potassium iodide solution, potassium chloride and iodine are formed. The balanced chemical equation for this reaction is 2KI + Cl2 → 2KCl + I2.
