Question

What is the balanced reaction between H2S+Cl2=S+Cl-

Answer 1

Balanced reaction between $H_2S+Cl_2\rightarrow S + Cl^-$

Explanation:

• As the product contains ions, the given equation can be balanced with help of the oxidation number method.
• The reactants involved in the given reaction are hydrogen, Sulphur and Chlorine.
• The change in the oxidation number of the reactants in the products are as follows:
• As sulfur is losing its two electrons it changes from $S^{2-} to S^0$ as shown in the following equation

$S^{2-} - 2e^- = S^0$

• Chlorine gains 2 electrons donated by the sulfur. Thus it changes from $Cl_2^0 to 2Cl^-$

$Cl_2 + 2e^- = 2Cl^-$

• The proton ($H^+$) remains unchanged thus the balanced equation for the given reaction is as follows:

$H_2S+Cl_2\rightarrow S + 2Cl^- + H^+$

Answer 2

Answer:

oxidation reaction =H2S = S

reduction reaction = Cl2 = Cl-

confirm answer is H2S + Cl2 = S+2H^++2Cl^-
