Question: Is BR Stable?

How long does it take bromine to kill bacteria?

It can take anywhere from two hours to twenty-four hours to dissipate.

Of course, that range depends on how high the levels are.

Just keep testing the water to ensure the level reaches the safety levels.

Bromine and chlorine are very similar in their uses, but bromine does dissolve slower than chlorine..

How is bromine used by humans?

Bromine, chemical symbol Br and atomic number 35, is a reddish-brown liquid that is being used in key applications such as water treatment, the reduction of mercury emissions, fire safety, energy storage and generation, production of pharmaceuticals and enhanced quality rubber.

What does bromide do to the human body?

Bromide was once used as an anticonvulsant and sedative at doses as high as 6 g/day. Clinical symptoms of bromide intoxication have been reported from its medicinal uses. Large doses of bromide cause nausea and vomiting, abdominal pain, coma and paralysis.

Is bromine stable or unstable?

Natural bromine is a mixture of two stable isotopes: bromine-79 (50.54 percent) and bromine-81 (49.46 percent). Of the 17 known radioactive isotopes of the element, bromine-77 has the longest half-life (57 hours).

Is bromine bad for the environment?

Environmental effects of bromine When they are applied in greenhouses and on farmland they can easily rinse off to surface water, which has very negative health effects on daphnia, fishes, lobsters and algae. Organic bromines are also damaging to mammals, especially when they accumulate in the bodies of their preys.

Is bromine essential for life?

Bromine – an element with atomic number 35 and the chemical symbol Br – is the 28th chemical element essential for tissue development in humans and all other animals, says a team of researchers led by Prof Billy Hudson of Vanderbilt University School of Medicine.

Is Br or I more reactive?

Most reactive: Fluorine (F). … Order from most reactive to least reactive: Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), Astatine (At), Tennessine (Ts).

Why is Br more selective than CL?

Bromination of alkanes occurs by a similar mechanism, but is slower and more selective because a bromine atom is a less reactive hydrogen abstraction agent than a chlorine atom, as reflected by the higher bond energy of H-Cl than H-Br.

Is bromide still used?

Methyl bromide also depletes the ozone layer. Therefore, along with other countries, the United States has phased out production and consumption of methyl bromide with important exceptions for critical uses as well as quarantine and preshipment.

Is chlorine or bromine safer?

The spa chemicals you use are all safe in the proper amounts. But some people may react differently to them. Chlorine: Can be harsh on the skin, hair, and eyes, especially at too-high levels. … Bromine: Is gentler on your skin than chlorine, but can be a bit more difficult to wash off after a long soak.

Does bromine kill algae?

Bromine is an effective algaecide, particularly against difficult to control mustard and black algae, and its algaecidal properties are well known. … However, sodium bromide alone will not kill algae. To be effective, it must be used in conjunction with an oxidizer, typically chlorine.

Is bromine used for?

Uses and properties It is toxic. Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates. Some uses are being phased out for environmental reasons, but new uses continue to be found. Bromine compounds can be used as flame retardants.
