Hydrogen sulphide gets oxidised to ___by conc. sulphuric acid.
Sulphuric acid in its concentrated form, oxidises hydrogen sulphide to sulphur according to the following reaction. H2S+H2SO4→2H2O+SO2+S
Metals get oxidised to their respective sulphates when they are reacted with conc. sulphuric acid.
Conc. sulphuric acid oxidises phosphorus to
Conc. sulphuric acid acts as an oxidising agent when it undergoes :
What property of conc. H2SO4 is made use of in each of the following cases ? Give an equation for the reaction in each case :
(a) in the production of HCI gas when it reacts with a chloride,
(b) in the preparation of CO from HCOOH,
(c) as a source of hydrogen by diluting it ans adding a strip of magnesium,
(d) in the preparation of sulphuric acid by warming a mixture of conc.sulphuric acid and copper-turnings,
(e) hydrogen sulphide gas is passed through concentrated sulphuric acid.
