Sodium And Chlorine Atoms

Chlorine was first discovered by a man whose profession was in the medical field. However, since it was 1774, the technology wasn’t as advanced and therefore led him to misleading conclusions. Carl Wilhelm Sheele was a Swedish pharmacist who, “released a few drops of hydrochloric acid onto a piece of manganese dioxide in his lab, and a greenish-yellow gas was produced in a matter of seconds…” (Alchin, Linda. “The Element Chlorine.” What Is Chlorine?, www.elementalmatter.info/element-chlorine.htm.). Before Sir Humphry Davy, people thought that Chlorine was a form of oxygen. Sir Humphry Davy later proved otherwise. Although this element was never thought to be used this way, in World War I Chlorine was used as a “choking agent”. Men would suffer

Chlorine is used in pools in either a gaseous or as sodium or calcium hypochlorite. The chlorine is added to water to help prevent people from getting sick from disease-producing microorganisms. The chlorine that is added and reacts with the organic material and metals in the water is the chlorine demand for the water as it will not be available for any disinfection that keeps people from getting sick while in the pool. The residual test is

Chlorines history was never intended to be used as a weapon. In 1774 German-Swedish chemist Carl Wilhelm Scheele discovered the chemical (Chlorine, 2013). The uses for liquid and solid chlorine was found to kill bacteria and has been developed to be used in small quantities to

Chloramines are disinfectants used to treat drinking water. Chloramines are intended to quickly kill most bacteria, viruses, etc, but we are now using chloramines as a matter of convenience, there are far safer alternatives.

The way chlorine kills the bacteria is because chlorine splits into different chemicals like HOCI (Hypochlorous acid) and OCI (Hypochlorite ion). HOCI and OCI both dissolve in water. These two chemicals kills bacteria and they do that by attacking the lipids in the cell. HOCI is able to oxidise (loss of electrons) organisms in seconds and OCI is able to oxidise (loss of electrons) organisms in about 30 minutes. This means that chlorine kills bacteria straight away because of the HOCI but then the OCI kills bacteria later for example people who go into the swimming later. Also chlorine does not harm us humans but maybe you get some dry skin or hair. This is really effective because HOCI and OCI in the chlorine kills bacteria which can make

The main constituent of household bleach is a chemical called sodium hypochlorite. __Sodium hypochlorite__ in liquid form is greenish or yellowish in color and is commonly referred to as bleach because it is the active ingredient in bleach. Its chemical formula is __NaClO__, composed of one sodium (Na) atom, one chlorine (Cl) atom and one oxygen (O) atom. Its chemical structure shows that hypochlorite ion (ClO-) has an ionic bond with sodium (Na+) ion.

It is important to use de-ionized water in this experiment because you don’t want the electrolytes in the water to

The second most important piece of information taken from Figure 1 is the number of protons in the model. The number of protons corresponds to the atomic number, which can be found on the Periodic Table. Chlorine has a total of 17 protons, so there are 17 protons drawn on the Bohr model. From the inside out, the number of electrons drawn on each shell are 2, 8 and 7. The third piece of information taken from Figure 1 is that Chlorine has a total of 18 electrons. This means that there is one more electron than there is protons. Because of this, chlorine becomes a negatively charged atom. Chlorine desperately wants another electron to fill its outer shell, so it bonds very nicely with atoms in which it can share an electron with. Chlorine has the ability to create many ions because of its need for another electron to become stable. The molecular structure of chlorine is important to understand. The Bohr model of chlorine helps to understand why chlorine reacts the way it does with other elements. Without the knowledge of what chlorine can work with and what it cannot, it is now possible to create medications in order to treat medical disorders. Knowing the facts of the molecular structure take away guess work and thus speed up the process of medical

Chloride is an anion, meaning it is a negatively charged ion. Chloride is formed when the element chlorine gains an electron. The electron configuration for chloride is 1s2, 2s2, 2p6, 3s2, 3p6. Chloride makes up 0.15 percent of our body weight, and helps with the distribution of fluids in our body. Chloride is used in water to act as a disinfectant to kill bacteria and microorganisms. There are many concerns about this ion as

Chemical bonding is responsible for the strong mutual attraction, which prevails between atoms. Atoms are the basic buildings blacks for all types of matter. Atoms are capable of joining together to form molecules, which are responsible for forming most of the objects around us. Atoms forms chemical bonds because lone atoms are extremely reactive and unstable; they form bonds to achieve stability. Our world is made up by so many different elements, and they are responsible for combining together in thousands of different arrangements, in different states of matter, because of a process called chemical bonding. Many atoms, through the process of chemical bonding, lose a few extra electrons to integrate with the octet rule.

Chlorine destroys pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. The chlorine compounds exchange atoms with other compounds, such as enzymes in bacteria and other cells. When enzymes come in contact with chlorine, one or more of the hydrogen atoms in the molecule are replaced by chlorine. This causes the entire molecule to change shape or fall apart. The then enzymes function improperly, causing the cell or bacterium will die.

Chlorine & Chlorination: Chlorine isn’t only used in swimming pools. It’s also used to kill bacteria in municipal water supply systems and wells. Chlorine is an excellent disinfectant choice because low amounts are effective in neutralizing bacteria, providing another alternative to bottled water.

The leisure pool (swimming pool) is one of the main sources which attracts the public to the centre. In order to keep the pool clean, a chemical known as chlorine. Chlorine is chemical that is toxic, irritant and is pale green. Chlorine is proven is kill bacteria that are hazardous to humans through a chemical reaction. This chemical reaction takes place as once the chlorine is placed in the water it breaks down in to various chemicals which including two chemicals known as hypochlorous acid (HOCI) and hypochlorite ion (OCI-). These two specific chemicals kill microorganism and bacteria by destroying the enzymes inside the cell as the lipids (fats) on the cell walls are attacked by the chemicals. Once this process occurs the cells are oxidized and are made harmless.

Chloroform is a clear, natural occurring, sweet tasting liquid medal that can be extremely deadly. Even though Chloroform is a natural occurring element, most chloroform is manmade. Chloroform can be found in household cleaning products, swimming pools, and even in small amounts in water. Chloroform can form by mixing alcohol and bleach, or just breaking down any type of chlorine based substance (“How to Make Chloroform…”). Chloroform is ok if only exposed to small amounts, but if over exposed to it the chemical can be extremely dangerous. Some of the main ways people are exposed to chloroform is: contaminated water, household cleaning products, and even swimming in a pool. The effects of chloroform vary based on how it was exposed, how long it was exposed for, and individual health. Directly after being exposed to chloroform through the air, some common side effects are: dizziness, feeling tired, and having headaches. If expose for too long some much more severe impacts occur such as: cancer, kidney failure, liver failure, and infections in blood flow (“Chloroform”). Chloroform isn’t the most known substance, and its long-term effects on humans aren’t even really well documented so there is very little we know about what it does to animals. We do know, just like humans, animals have several organ problems resulting from direct over exposure to chloroform such as kidney failure, heart disease, and blood problems (“Medical Discoveries”). According to EcoUSA.com, most

Bleach or sodium hypochlorite is a common household cleaner in an average Canadian home, but what is the effect of bleach on human health? Some background information about bleach before we begin is that it is a pale yellow liquid that has a chlorine odor (Sodium 2016). The manufacturers generally supply bleach as a dilute aqueous solution because it is extremely reactive and unstable.  Bleach will eventually decompose into a variety of by-products, such as oxygen, chlorine gas, and salt (Schueller 2014). To prevent this decomposition from occurring too rapidly, bleach should be stored away from light or heat. The active ingredient in sodium hypochlorite; consists of a negatively charged hypochlorite ion (CLO-) and positively charged sodium
