Depends on it's concentration.
No. Na2S is highly basic.
The name for the compound with the formula Na2S is sodium sulfide.
Na2S is basic.
CdBr2 + Na2S --> CdS + 2NaBr.
2HCl + Na2S ---> 2NaCl + H2S
The pH of a saturated solution of calcium sulfate is 7.7.
Na2S
No. Na2S is highly basic.
The name for the compound with the formula Na2S is sodium sulfide.
Na2S is basic.
The hydrate of Na2S is Na2S.9H2O. Its name is sodium sulfide nonahydrate.
CdBr2 + Na2S --> CdS + 2NaBr.
2HCl + Na2S ---> 2NaCl + H2S
Na2S does not contain carbon or hydrogen. Na2S is formed by sodium ions and sulfide ions. So Na2S is not a organic compound.
Na2S is produced by passing H2S gas through a sodium hydroxide solution until weak alkaline pH, followed by evaporation of water and crystallisation.H2S + 2NaOH --> Na2S + 2H2OHOWEVER :Don't do this by yourself unless you're have fully safe laboratory conditions: H2S is very toxic!
Na2S
Initially Na+ and S2-, however depending on the pH the sulfide ion reacts with water to form HS-. S2- only persists when the pH is high (basic), which is the case if the sodium sulfide is dissolved in a relativellyt small amount of water.
