Na = +1
Na2 = Na(2) = +2
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.
Na2S
The balanced chemical equation for CdBr2 + Na2S is: CdBr2 + Na2S → CdS + 2NaBr
The correct formula for the ionic compound formed between sodium and sulfur is Na2S. Sodium is a group 1 element with a +1 charge, and sulfur is a group 16 element with a -2 charge. Therefore, two sodium atoms are needed to balance the charge of one sulfur atom.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
No, Na2S (sodium sulfide) is a basic compound. When dissolved in water, it forms hydroxide ions which makes the solution basic.
The oxidation number of sulfur (S) in Na2S is -2. In Na2S, there are two Na+ ions with a charge of +1 each, making a total of +2. Since the compound is neutral, the oxidation number of sulfur must be -2 to balance out the charges.
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 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.
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.
It is Na2S
