The smell is similar to the smell of hydrogen sulfide (rotten eggs).
Na2S
Sodium sulfide
Na2S
The metallic ion in this case is Na+, or sodium. If there is a metal ion in a chemical formula, it will be the one written at the beginning.
This compound is sodium sulfide.
When HCl is added to Na2S, hydrogen sulfide gas (H2S) is formed. This gas has a characteristic rotten egg smell and is toxic in high concentrations.
Na2S
The balanced chemical equation for CdBr2 + Na2S is: CdBr2 + Na2S → CdS + 2NaBr
No, Na2S (sodium sulfide) is a basic compound. When dissolved in water, it forms hydroxide ions which makes the solution basic.
The pH of a solution of Na2S (sodium sulfide) depends on its concentration. When Na2S dissolves in water, it forms hydroxide ions which makes the solution basic. Therefore, the pH of a solution containing Na2S would typically be greater than 7.
Na2S + 2HCl = 2NaCl + H2S (smelly toxic gas) Sodium sulphide + hydrochloric acid => Salt (Sodium chloride) and Hydrogen sulphide
Na2S is a strong base because it completely dissociates in water to form Na+ and S2- ions. When Na2S reacts with an acid, the S2- ion can act as a base and accept a proton from the acid, leading to the formation of HS- ions or H2S gas, depending on the strength of the acid. The reaction between Na2S and an acid results in the neutralization of the acid.
The hydrate of Na2S is Na2S.9H2O. Its name is sodium sulfide nonahydrate.
Na2S does not contain carbon or hydrogen. Na2S is formed by sodium ions and sulfide ions. So Na2S is not a organic compound.
It is Na2S
