If chlorine is bubbled into water and the resulting yellowish-green solution is exposed to bright sunlight for a while, the solution will decompose giving out

Answer Details

When chlorine is bubbled into water, it reacts to form a yellowish-green solution of aqueous chlorine. This solution is unstable and will decompose on exposure to sunlight, forming oxygen gas and aqueous hydrochloric acid. The reaction can be represented as follows: 2Cl2 + 2H2O + sunlight -> 4HCl + O2 Therefore, the correct answer is "oxygen and leaving behind aqueous hydrochloric acid."
