In 1840 it was discovered that bromine(7726-95-6) had some advantages over the previously used iodine vapor to create the light sensitive silver halide layer used for daguerreotypy.
Potassium bromide and sodium bromide were used as anticonvulsants and sedatives in the late 19th and early 20th centuries, until they were gradually superseded by chloral hydrate and then the barbiturates.

What is the color change between aqueous bromine and sodium chloride?
There will be no colour change between the two, as chlorine is more electronegative than bromine and will maintain its negative charge, meaning that the bromine will not react and the orange colour persists.
What color does bromine water change when you mix it with unsaturated fat?
There is no colour change
What happens When is bromine is added to cyclohexane?
no colour change
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
What colour does bromine water change when you mix it with saturated fat?
It goes red

How can bromine water test the difference between alkanes and alkenes?
Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
What colour does bromine water change when you mix it with saturated fat?
It goes red
When we place aluminium foil into liquid bromine and find a white solid is that chemical or physical property?
It is a chemical change. The aluminum reacts with the bromine to form aluminum bromide.
What is the difference between bromine and liquid bromine?
Liquid bromine is the Real Bromine, while Bromine water is a mixture of Bromine and Water
What happens when bromine is added to water?
nothing happens but you can add iodine then it will change coulur
What is the difference between bromine water and liquid bromine?
Liquid bromine is the Real Bromine, while Bromine water is a mixture of Bromine and Water
When bromine reacts with sodium to form a white solid is it a physical or chemical change?
chemical change a physical change changes the apperance chemicals changes change the substance
Why does liquid bromine change to gas at room temperature?
Actually, Bromine is a Liquid at room temperature it never changes to a gas at room temperature when it is heated up to 300 or so...Kelvin.
