What is the chemical name for HSCN?
HSCN is the chemical formula of thiocyanic acid.
Why is KSCN neutral while NaF is basic despite the fact that HSCN is a weaker acid than HF?
HSCN is not a weaker acid than HF. The Ka for HSCN is approximately 1.2x10^-1 and that for HF is approximately 7x10^-4, making HSCN considerably stronger than HF. In fact, a solution of KSCN would have a pH very slightly above 7.0, but close to neutral because it is almost a strong acid. A solution of NaF will have a pH that is basic because it is the salt of a strong base and a weak acid.
What is the oxidation for S?
That depends on the compound that it is in but it is often found in the oxidation states 2-, 4+, and 6+. In its elemental for the oxidation state is 0, which is true of all elements. In sulfides, thiols, and similar compounds such as H2S, K2S, CH3SH and HSCN it s int the 2- oxidation state. In sulfur dioxide (SO2) and sulfites such as Na2SO3 and SrSO3 it is in the 4+ oxidation state. In sulfur trioxide (SO3), sulfuric acid (H2SO4), and sulfates such as MgSO4, K2SO4, and NaHSO4 it is in the 6+ oxidation state..
What is the oxidation number for S in S 2?
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.Atomic sulfur has oxidation number of 0. Its simple ion, sulfide carries oxidation status -2. While forming numerous compounds, the oxidation number of sulfur can vary form -2 to +6.
