Bromine
Symbol – Br
Molecular Weight – 79.904 u
Atomic Number – 35
CAS No – 7726-95-6
Bromine was discovered independently by two chemists Carl Jacob Lowig and Antoine Balard in 1825 & 1826 respectively. Commercially Bromine isextracted from brine pools mostly in US, Israel and salt pan brine inIndia, At standard temperature and pressure it is liquid, at high temperature, Bromine compounds readily dissociate to yield free bromine atoms.
Properties
| Melting Point | -7.2oC |
| Boiling Point | 58.8oC |
| Density | 3.1028 g/cm3 |
| Colour | Reddish – Brown |
Uses
A wide variety of Organobromine compounds are used in industry
- Pharmaceutical
- Flame retardants
- Well drilling fluids
- Agricultural chemicals
- Dyestuffs
- Insecticides
- Chemical Intermediates
Effects
Elemental bromine is toxic and causes chemical burns on human flesh. Inhaling bromine gas results in coughing, choking and shortness of breath
Safety and Handling
Handling should be done with wearing proper PPEs. It should be carried in ISO tanks or tanks lined with lead, supported by strong metal frames.
Iodine
Symbol – I
Molecular Weight – 126.904 u
Atomic Number – 53
CAS No – 7553-56-2
Iodine was discovered by the French Chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac.
Sodium Iodide has a very wide and important applications, and it is extracted from the caliche and reduced to iodide by sodium bisulphite.
Properties
Phase at STP Solid
| Melting Point | 313.7oC |
| Boiling Point | 184.3oC |
| Density | 4.933g/cm3 |
| Colour | Violet |
Uses
Iodine is used as an antiseptic (Ex.: Tincture of iodine, Povidone Iodine) Iodine is also used for Quantitative volumetric analysis
- Pharmaceuticals and disinfectants,
- Printing inks and dyes,
- Catalysts,
- Animal feed supplements and
- Photographic chemicals.
Effects
Iodine is toxic if taken orally. Excess iodine can be more cytotoxic in the presence of selenium deficiency. Iodine is also a skin irritant and can cause skin damage and tissue damage.
Safety and Handling
Handling should be done with wearing with proper PPEs
Zinc
Symbol – Zn
Molecular Weight – 65.38 u
Atomic Number – 30
CAS No – 7440-66-6
Zinc was discovered by Indian metallurgists before 1000BC, but it was first isolated by AntreasSigismundmarggraf in 1746.
Zinc is refined by Froth Flotation, roasting and final extraction using electro winning of sphalerite (a Zinc Sulphide Mineral)
Properties
Phase at STP Solid
| Melting Point | 419.53oC |
| Boiling Point | 907oC |
| Density | 7.3g/cm3 |
| Colour | Silvery-Grey |
Uses
Zinc is used as alloys(Brass). Anticorrosion agent and galvanization (coating of Iron and Steel).
Zinc powder as used as propellant in modern rockets
Effects
Consumption of excess Zinc cause ataxia lethargy and copper deficiency in children Zinc deficiency causes delate sexual maturation and diarrhea
Safety and Handling
Avoid creating dust as dust may present a fire hazard. Avoid breathing dust or fumes. Handling should be done with wearing with proper PPEs.
