Transcript of CHLORINE
The Meaning of Chlorine
Chlorine was derived from the greek word Chloros, meaning a greenish yellow. referring to the gas color. Chlorine is extremely poisonous at its natural state
What it is used for
Chlorine was made in a lab . Carl Wilhelm Scheele, who was a swedish chemist was experimenting and combined the mineral pyrolusite (MnO2) with hydrochloric acid (HCl), This happened in 1774. People did not know if this was an element or not until 1810 when Sir Humphry Davy proclaimed it was indeed an element. Chlorine is found 2nd in the order of abundance in the earths crust
What Chlorine is used for
Chlorine is frequently used as an antiseptic and is used to make drinking water safe and to care for swimming pools. Huge amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints
second most common halogen on the planet
it took almost 200 years after the discovery to become an element.
Chlorine in its pure form is yellowish-green, but its common compounds are usually colorless.
chlorine can combine with practically any element to form a chloride.
in many chloride forms chlorine is very vital for living organisms
from pools to pipes
a greenish yellow color that is a gas at room temperature . The boiling point for chlorine is - 35 c and the melting point is -101c. Also, the density is 3.21 g/cm3. Next, the Atomic weight is 35.453. Chlorine is a deficient conductor of electricity due to its liquid state under usually conditions. However, when put below enormous pressures, it obtains a metallic structure that permits it to conduct electricity. The same thing also happens when heat conducts with chlorine.
Halogens are the family chlorine is in, along with iodine and Astatine. The halogen family is made up of all non - metals, they are also in the 17 th group. Chlorine is highly reactive and when combined with sodium makes table salt. chlorine is not flammable but when combined with other chemicals it does. Lastly, chlorine has an oxidation number of -1 to 7 which means it has a high oxidation level
