Some sulfides are described as "soluble", but yet one would not observe free S2- in solution. Explain this fact, and show the process that does occur when sulfides dissolve in water. Base your explanation on Lewis and Brønsted-Lowry acid-base theory. 


Expert Answer

Step 1

Lewis acid is any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.

Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.

Step 2

According to the Bronsted-Lowry theory,

An acid is a chemical species capable of donating a proton or hydrogen cation.

 A base is chemical species capable to accept a proton or hydrogen ion in aqueous solution.

Step 3

The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insolub...
