Question

Before doing an experiment with sulfur dioxide, you look up some safety mation. Answer the question below, and state what information you used to answer the solution. Is sulfur dioxide a solid, liquid or gas at room temp? How do you know? Is sulfur dioxide a fire hazard? How fo you know? Is sulfur dioxide a health hazard? How do you know? Is there a risk sulfur dioxide reacting with something else? How do you know? Based upon the information here, what precautions should be used ans why should they be used when working with sulfur dioxide in the laboratory?

Explanation / Answer

a: SO2 is a gas at room temprature because SO2 having covalent bond at simple structure like CO2 . Like all simple molecules it will have the weakest intermolecular forces, Van der Waals.

It is also a polar molecule, because it has a bend shape as a result of having two (double) binding pairs and a lone pair on the central S atom. The S atom is less electronegative that O, so the S-O bonds are polar and not symmetrically opposed, so the dipoles don't cancel each other out and we have permanent dipole-dipole intermolecular forces which are stronger than Van der Waals, so we'd expect a higher melting and boiling point than CO2.i studied the in P block

b)yes ,it is a fire hazard.Containers may explode in heat of fire or they may rupture and release irritating toxic sulfur dioxide. studied in Chemical enggineering

C)yes. It may cause death or permanent injury after very short exposure to small quantities. 1,000 ppm causes death in from 10 minutes to several hours by respiratory depression. It is an eye and respiratory tract irritant. Persons with asthma, subnormal pulmonary functions or cardiovascular disease are at a greater risk studied in chemical engg.

d) yes its a risk because SO2 is a acid and it reacts exothermically with  bases such as amines, amides, metal oxides, and hydroxides
