Chapter 22: Problem 46

Show how you would use elemental sulfur, chlorine gas, metallic sodium, water, and air to produce aqueous solutions containing (a) \(\mathrm{Na}_{2} \mathrm{SO}_{3} ;\) (b) \(\mathrm{Na}_{2} \mathrm{SO}_{4}\) (c) \(\mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3} .\) [Hint: You will have to use information from other chapters as well as this one.].

Short Answer

Expert verified
The solution to the given problem is the three reactions: (a) \(S + O_2 + 2Na \rightarrow Na_2SO_3\), (b) \(2Na_2SO_3 + O_2 \rightarrow 2Na_2SO_4\), and for (c) first \(S + O_2 \rightarrow SO_2,\) and \(S + Cl_2 \rightarrow SCl_2\), then \(SO_2 + SCl_2 + 2Na + H_2O \rightarrow Na_2S_2O_3 + 2HCl\).

Step by step solution

01

Solving for \(Na_2SO_3\)

The first compound to produce is \(Na_2SO_3\). The starting reactant is sulfur. Upon reacting with oxygen in the air and sodium, sulfur forms sodium sulfite. The reaction is as follows: \[S + O_2 + 2Na \rightarrow Na_2SO_3\]
02

Solving for \(Na_2SO_4\)

To produce \(Na_2SO_4\), we start with \(Na_2SO_3\), the product from the previous step, and react it with oxygen. This forms the required product, sodium sulfate. The reaction can be written as: \[2Na_2SO_3 + O_2 \rightarrow 2Na_2SO_4\]
03

Solving for \(Na_2S_2O_3\)

The third compound \(Na_2S_2O_3\) requires a two-step process starting from sulfur. Firstly, sulfur reacts with oxygen in the air and chlorine to form sulfur dioxide and sulfur monochloride: \[S + O_2 \rightarrow SO_2,\] \[S + Cl_2 \rightarrow SCl_2\]. In the next step, these products react with water and sodium to form sodium thiosulfate and other by-products. The reactions are as follows: \[SO_2 + SCl_2 + 2Na + H_2O \rightarrow Na_2S_2O_3 + 2HCl\]
