In general Sodium metal is very poison,But Nacl is not poison.How?

Answer 1

Because poisoning is a chemical reaction and different compounds react differently than their component elements. NaCl is table salt, and not a metal or a gas or a poison or explosive, even though sodium is a metal that reacts explosively with water, and chlorine is a poisonous gas.

Hydrogen is a combustible gas, and we can breath oxygen, but H2O is not a gas at room temperature, doesn't burn, and isn't breathable, but is obviously potable. However, if you burn hydrogen, that is apply heat in the presence of oxygen, then you get heat and water as the output.

Answer 2

Sodium metal is oxidized by water vapor in the air and produces hydrogen gas, which is very combustible and tends to explode. This is why sodium metal is dangerous (sodium metal in itself is not poisonous as far as I know).
Sodium chloride is a sodium salt. It contains both sodium and chlorine atoms which are very tightly bound together. Because of this bonding the sodium atoms are not able to react with any other compound and table salt doesn't spontaneously combust when it comes into contact with humidity in the air.

Answer 3

sodium by itself is not poisionous. if exposed to water and oxygen it forms hydrogen gas and is potentially explosive. you have sodium level in your body that helps with hydration, nerve impulses, and your heart rhythum. NaCl is bonded together and can be ionized and solvated in water. THe properties change when the bonds change. Chlorie is poisionous too, and once added to sodium forms table salt which can kill you.

Answer 4

Sodium metal has no intrinsic charge and is very reactive. That's why it's dangerous. Sodium ion has lost its valence electron and so is already "reacted". Thus, it is not as dangerous. Your body is full of sodium ions.

Answer 5

when two or more elements react chemically to form a compound the properties of the compound will be different from the properties of the elements that combine to form the compound
