Well, Bromine is a deep-red, oily liquid with a sharp smell. It is toxic.
Uses
Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates.
Bromine compounds can be used as flame retardants.
They are added to furniture foam, plastic casings for electronics and textiles to make them less flammable.
Organo bromides are used in halon fire extinguishers that are used to fight fires in places like museums, aeroplanes and tanks. Silver bromide is a chemical used in film photography.

The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; For sodium thiosulfate (Na2S2O3·5H2O), this is (248.17/1) g.
In case of Sodium Thiosulfate the reation proceeds as under: I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI 2 Na2S2O3 ≡ I2 ≡ 2 e Hence for one Na2S2O3 ≡ 1 e
Thus Molecular weight divided by 1 is the equivalent weight & hence both have same value.

Bromine is dangerous because it is a corrosive liquid and a toxic, choking gas.

Molar mass ofNa2S2O3.5H2O=2*23+32*2+3*16+5*18=280
Equivalent mass=molar mass/total positive valency=280/2 =140
So 140 g of sodium thiosulphate dissoved in 1 litre will form 1N solution
14 of it dissoved in 1 litre of water will give .1N solution

Let's have a look at the composition: [math]Na{_2}S{_2}O{_3}[/math]
According to the broenstedt definition of acid, an acid is able to donate protons (H+). Do we have any protons? No, so it isn't an acid.
A base is able to accept protons. That's something that can happen:
[math]{Na_2}{S_2}O{_3} + 2 H^+ ightarrow {H_2}{S_2}{O_3} + 2Na^+[/math]
The product, thiosulphuric acid will decomposes immediately and form water, sulphur and sulphur dioxide.
