Sodium sulfide solutions are effective leaching agents for the concentration of stibnite from ores.
Mercury can be leached from ores and concentrates with a solution of sodium hydroxide and sodium sulfide.
It is removed from wood pulp in the manufacture of paper, usually by treating with agents such as sulfur dioxide, sodium sulfide, or sodium hydroxide.
Ford scientists in Great Britain had developed something called the sodium sulfide battery, but so what?
The liquor is an aqueous solution of sodium hydroxide and sodium sulfide.
The variables studied were potassium amyl xanthate (KAX) as a collector, sodium sulfide (Na2S) and pH.
Sodium sulfide (Na2S) was also dissolved in double-distilled water separately as per molar concentration.
The cadmium chloride solution was placed into an autoclave followed by the addition of sodium sulfide.
After the addition of sodium sulfide, the color changed from white to greenish yellow.
Just as in the prior experiments, the methanogens produced methane at comparable levels to those seen with sodium sulfide as the reductant, indicating that sodium sulfide did not reduce the perchlorate to any significant extent.
The standard procedure for growing methanogens typically includes sodium sulfide, a reducing agent, to reduce residual molecular oxygen.
