The process involves treating a sludge Input Equation Balanced Equation; NaNO3 + KOH =NaOH + KNO3: NaNO3 + KOH = NaOH + KNO3: Na2CO3+Ca(OH)2=NaOH+CaCO3: Na2CO3 + Ca(OH)2 = 2NaOH + CaCO3 Should the quantity of Ca(OH)2 used be sufficient to raise the Na2S content of the treated liquor to above the maximum permissible Na2S value for that particular operation, after the Ca(OH)2 treatment, the liquor in tank 32 may be gassed with enough H2S, preferably pure, to lower the Na2S content to the desired amount. Input Equation Balanced Equation; Al(OH)3 + HNO3 = Al(NO3)3 + H2O : Al(OH)3 + 3HNO3 = Al(NO3)3 + 3H2O: Al + O2= Al2O3: 4Al + 3O2 = 2Al2O3 Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9 H 2 O. Both the anhydrous and the hydrated salts are colorless solids. They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Instructions. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button.

Il solfuro di calcio è un composto chimico di formula CaS.. È stato studiato per il riciclo del gesso, un prodotto del processo di desolforazione dei gas di scarico industriali. Come per altri sali che contengono ioni solfuro, il solfuro di calcio emette un odore tipico di H 2 S, a causa delle piccole quantità di sale che si idrolizzano a contatto con l'umidità dell'aria. CaO + H 2 O → Ca(OH) 2 + 1 136 kJ /kg di CaO. Questa reazione viene utilizzata spesso per produrre bevande in lattina calde.
