Is Sodium Sulfide Soluble In Water?

Yes, sodium sulfide (Na2S) is soluble in water. It is a highly water-soluble compound and readily dissolves in water to form an alkaline solution. This is due to the ionic nature of sodium sulfide, which allows it to dissociate into its constituent ions (Na+ and S2-) when it comes into contact with water. The resulting solution will have a pH greater than 7 due to the presence of hydroxide ions (OH-) generated from the reaction between water and sulfide ions (S2-).
