Question

galena gives metal oxide + gas


what is the difference between oxidation state in sulphur in product and reactant​

Answer 1

Lead can be prepared from galena [lead(II) sulfide] by first roasting the galena in oxygen gas to form lead(II) oxide and sulfur dioxide. Heating the metal oxide with more galena forms the molten metal and more sulfur dioxide.

Oxidation number of sulphur atom involved in coordinate bond formation is (+5) and that of middle sulphur atom is zero. Hence, the difference in oxidation number of two types of sulphur atoms will be (+5)
