prepared directly by dissolving iodine in water because iodine is too volatile so it is almost impossible to avoid loss while the solution is being prepared. Therefore iodine is prepared in situ by mixing pure potassium iodate (KIO3 ) and potassium iodide (KI) in acidified medium. IO3- + 5I- + 6H+ → 3I2 + 3H2O The excess iodine that has not reacted with ascorbic acid in fruit juices (vitamin C) is then back titrated by standardized sodium thiosulphate solution. Iodine can be decolourized

I worked in the medical/surgical unit‚ so it was a different experience than being with newborn babies‚ especially because I was more involved with the patients‚ like getting them fresh water

In Future Physicians‚ I participated in field trips to children’s hospitals and also participated in two blood banks. Currently I hold a job at Maas Brothers.

hear on television at regular intervals innovative punishments like electric shocks being doled out to students. There are particularly heart rending moments like the whole initial boarding school sequence – set to the song “Tujhe Sab To Pata Hai Na Maa” which covey the unspoken emotions of a child separated from his mother when he most needs her. It’s been a long time since I had tears in my eyes (for the right reasons) when watching a film – No emotional manipulation here thankfully!
