When you open a savings account you'll get a small book called a register (like a checkbook register) where you write your beginning balance (the amount you originally deposit) and all of your future deposits and withdrawals. This tool helps you keep track of how much money you have.
Hydrogen Sulfide: Nature's Chemical Helper. The main use for hydrogen sulfide is in the production of sulfuric acid and elemental sulfur. Manufacturers use sodium hydrosulfide, sodium sulfide and similar inorganic sulfides to create products such as pesticides, leather, dyes and pharmaceuticals.ydrogen sulfide is also used in chemical warfare. Many industrial entities, such as iron smelters, landfills, food processing plants and breweries, produce or use hydrogen sulfide.
Ammonium sulfide is a very useful reagent in mineral analysis. It's easy to prepare in the modestly-equipped laboratory, though there's the significant hazard of hydrogen sulfide during its production.he ammonium sulfide solution, prepared as outlined above, can be used to precipitate certain metal cations as sulfides (some, such as iron, precipitate as hydroxides if the pH is adjusted toward alkalinity). For detailed information on sulfide precipitations, see Orsino Smith's procedures P-8 and P-14 (1946).
