Draw the structur
(i) the structure of pyrosulphuric acid or oleum H2S2O7 is -
In the above structure of H2S2O7, each S atom is connected with 3 oxygen atoms(2 of them are connected with double bond and another is connected with a single bond which acts as connector in between these 2 S atoms)
• The structure of XeOF4 is square pyramidal-
• When chlorine gas reacts with hot and concentrated NaOH a disproportionation reaction takes place .
• In this case Cl (0) oxidises to NaClO3 ( +5) and reduces to NaCl (-1) simultaneously.
6NaOH + Cl2 --> 5NaCl + NaClO3 + 3H2O
• When Sulphur dioxide is passed through an aqueous solution of Fe (III) salt SO2 acts as an reducing agent and eventually converts Fe (III) to Fe (II).
2Fe3+ + SO2 + 2H2O → 2Fe2+ + SO42- + 4H+
