Chapter 15: Problem 8

Discuss the chemical properties of \(\mathrm{H}_{2} \mathrm{~S}\) and \(\mathrm{SO}_{2} \mathrm{Cl}_{2}\).

Short Answer

Expert verified

Hydrogen sulfide (H2S) is a weak acid, has metallic reactions, and can be oxidized or reduced. Meanwhile, sulphur dioxide chloride (SO2Cl2) is a polar compound, reacts with water and metals, and breaks down in water to form acids.

Step by step solution

Chemical Properties of Hydrogen Sulfide (H2S)

Hydrogen sulfide (H2S) is a colorless gas that has the smell of rotten eggs. It is composed of two hydrogen atoms and one sulfur atom.\n1. It is a weak acid in solution and ionizes slightly.\n2. It reacts with metals to produce metal sulfides, which are typically insoluble, hence evidence of the weak acid properties of hydrogen sulfide.\n3. It can undergo oxidation or reduction. A complete reaction with oxygen leads to the formation of water and sulfur dioxide:\n \[2 H2S(g) + 3 O2(g) \rightarrow 2 H2O(l) + 2 SO2(g)\]\n4. Hydrogen sulfide gas is poisonous to breathe

Chemical Properties of Sulphur dioxide chloride (SO2Cl2)

SO2Cl2 is composed of one sulfur atom, two oxygen atoms, and two chlorine atoms. \n1. It is a liquid at room temperature with a pungent odor.\n2. It is polar because there is a resultant Dipole movement.\n3. SO2Cl2 breaks down in water to form sulphuric acid and Hydrochloric acid:\n \[SO2Cl2 + 2 H2O \rightarrow H2SO4 + 2 HCl\]\n4. It reacts with most metals and metal oxides, creating the corresponding chlorides and sulfur dioxide:\n \[ SO2Cl2 + 2 Na2O \rightarrow 2 NaCl + Na2SO4\]
