Make the equations for H2S with 1) with bases; 2) with basic and amphoteric oxides; 3) with metals; 4) with salts
| May 26, 2021 | education
We compose the equation for the reactions of hydrogen sulfide with the following compounds.
a) with a base.
H2S + 2KOH = K2S + 2H2O.
When hydrogen sulfide interacts with potassium hydroxide, the result is a potassium sulfide salt and water.
b) with basic and amphoteric oxides. 3H2S + Al2O3 = Al2S3 + 3H2O.
The result is aluminum sulfide and water.
H2S + Na2O = Na2S + H2O.
The result is sodium sulfide and water.
c) with metals. H2S + Zn = MgS + H2
The result is magnesium sulfide and hydrogen.
d) with salts. 3H2S + 2Na3PO4 = 3 Na2S + 2H3PO4
The result is sodium sulfide and phosphoric acid.
