Vedclass · Answer

(D) The "Springs reaction" is a method for the preparation of sodium thiosulphate $(Na_2S_2O_3)$.In this reaction,sodium sulphide $(Na_2S)$ and sodium sulphite $(Na_2SO_3)$ react with iodine $(I_2)$ to produce sodium thiosulphate and sodium iodide $(NaI)$.The balanced chemical equation is: $Na_2S + Na_2SO_3 + I_2 	o Na_2S_2O_3 + 2NaI$.Therefore,the correct option is $(D)$.
