What is the anion in the ionic compound sodium sulfide?
Sodium sulfide is Na2S. Two ions can be separated: Na+ and S=. The negative ion S= is the anion.
What is the pka of Sodium sulfide?
Sodium sulfide (Na₂S) itself does not have a pKa value because it is a salt and does not donate protons in solution. However, it dissociates in water to produce sulfide ions (S²⁻), which are the conjugate base of hydrogen sulfide (H₂S). The pKa of H₂S, which is relevant for understanding the acidity of sulfide ion, is approximately 7.0 for its first dissociation.
What is the atomic number of sulfide?
Sulfide is not an element by itself, it is a compound. The atomic number of sulfur (S), the element found in sulfide compounds, is 16.
What the formula for dihydogen sulfide?
The formula is H2S. Di = 2, hydrogen = H, sulfide = S.
How many elements are in Zinc sulfide?
Zinc sulfide has two elements: zinc (Zn) and sulfur (S).
What is the formula for Be and S?
Beryllium sulfide is BeS.
What is the symbol for the ion sulfide?
S-3
What is the formula of the compound Ca and S?
The compound formed from calcium (Ca) and sulfur (S) is calcium sulfide (CaS). The formula for calcium sulfide is CaS.
Chemical formula for boron sulfide?
Boron Sulfide is a chemical compound with the formula B₂S₃. B = Boron S = Sulfur Its molar mass is 117.8 g/mol.
What is the formula for pottasium sulfide?
The formula for potassium sulfide is K2S. It consists of two potassium (K) ions and one sulfide (S) ion, which combine to form an ionic compound.
What elements does Copper Sulfide contain?
Copper sulfide typically contains the elements copper (Cu) and sulfur (S). The most common forms of copper sulfide are Cu2S (copper sulfide) and CuS (copper monosulfide).
Fe plus S FeS?
Yes, Fe (iron) plus S (sulfur) equals FeS (iron sulfide). If the iron ion is iron(ll) then it is iron(ll) sulfide; if it is iron(lll), then it iron(lll) sulfide.
