What Are Salt Water?

The materials used during the experiment included three plastic cups, three gummy bears, masking tape, marker, balance, calculator, tray, one plastic spoon, a measurement tray, and a ruler. The three plastic cups were used to hold the tap water, salt water, and sugar water. The masking tape and marker were used to label each cup with the

Some of the chemical properties are the same between salt water and fresh water. Salt water and fresh water

It “doesn’t really give you the whole picture” of what pollutants may be there, she explains. So she uses a combination of tests. These don’t look for particular chemicals. “This newer method lets the sample tell you what’s in it,” she

Several species and organisms rely on water to survive. Some organisms use it as a source to drink and others uses water as their living environment. This experiment is to calculate many aspects of the water that surrounds Corpus Christi. Water is the key to life on Earth and thus why water is so important. According to the Lab Report water quality is the quality of water and if it is considered acceptable drinking water. Water quality consist of its chemical, physical and biological characteristics. These properties can be studied through pH testing, nitrogen testing, Phosphorous testing and many other useful ways. Water quality is important because it allows scientist to identify if the water is in a good condition to drink or sustain life overall and it dramatically effects how healthy it is. The objective of this lab was to experiment if the water quality around the Corpus Christi is a reliable source of water for organisms and to reach an understanding of the water quality of the water surrounding Corpus Christi.

After approximately 2 minutes, the test tubes were removed from the water and placed into the test tube rack for us to observe any changes to the solutions. The resulting states and colors of the test tubes were as follows: The negative control water was clear and blue in color; coconut milk was opaque with a dark orange precipitate in the bottom and orange through the rest of its solution; karo syrup was opaque with a dark orange precipitate in the bottom and orange throughout its solution; potato chips solution remained cloudy with no precipitate and was blue in solution; peanut butter solution was opaque with a brown precipitate in the bottom and brown through its solution; and the banana baby food

As the leader of this clan, I chose to bring chlorine because I believe the chemical properties will be important as a wound disinfectant and to help purify water. The first important chemical property of chlorine is it’s solution when mixed with water to help kill bacteria in a wound. According to a website called https://www.leaf.tv/articles/the-effects-of-pool-chlorine-on-healing-wounds/ “When chlorine in the water penetrates the skin, it will help kill the bacteria in the wound.” This property is very important on the island for any medical issues that might occur while on the island. Even though, we hope for no medical issues to arise there is always the possibility and we want to ensure that, that has the littlest possible chance of happening,

This test kit is simply used to determine the purity level of MDMA substances. The color chart and information sheet are used to determine the purity

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

Salinity is the content and movement of dissolved salt in both land and water, and has a large impact on the landscape around it. Normally, deep roots soak up most of the water before it gets to the salt contained in the groundwater below the plant root area, but due to inefficient land use, irrigation, vegetation clearance and industrialised land, it has become easier for the salt to get to the top of the soil. This can effect agricultural production, the quality of the water, and can cause soil erosion. The salt from salinity can come from many different things including erosion of rocks, and rain adding salt over thousands of years (Nccma.vic.gov.au). Salinity is becoming a major problem in some parts of Australia including Western Australia,

As I read the final half of the novel People of the Book, I decided to focus on the symbolism of hands, and how they personify the emotions of the characters in the book, however, I became distracted when reading the Saltwater chapter. This chapter, which focuses on David and Ruth Ben Shushan, shares many similarities to the Passover story itself. This chapter takes place in Tarragona, Spain in 1492 at the time of the Spanish Inquisition. In the novel, Ruti (Ruth) is accused of Judaizing her brother, a Christian convert who is tortured by Spanish authorities. Ruth is in possession of the Haggadah and due to the police hunt for her she runs away from home. Similarly, in the story of Passover Moses leaves Egypt after he kills an Egyptian slave

There is a ton of mechanical hardware identified with swimming pools, including pumps, engines, chlorinators, warmers, blowers, clocks, and that's only the tip of the iceberg. These

However, based on the logical unlikelihood of stabiliser having a negative effect compared to only light, the conclusion was drawn that due to bonding between the free ions which were measured with the stabiliser there was a drastic decrease in the measurement of free ions. After analysing the data using the percentage decrease of concentration, rather than the concentration itself the results were more logically sound, showing control as the worst and cover as the best method for chlorine retention. As both conclusions show a pool cover to retain the most chlorine, it would be recommended that a pool cover would be the best option to protect the pool from chlorine loss due to UV light. Using a pool cover will retain the most hypochlorite ions in a pool, thus are better at maintaining pool safety, since there will be more chlorine available to disinfect the pool and it will need to be added less frequently. Pool covers also have many other advantages in pool protection, as they stop debris from entering the pool, and are also more environmentally friendly, since fewer.00000 chemicals (hypochlorite and isocyanuric acid) are introduced into the pool. The pool cover also has a greater lifespan than these chemicals, reducing the expenses of pool maintenance. The disadvantages of covers are that they can cause a heat increase in to pool

chlorine is a chemical element, its roughly basic ( 90 ). Naturally chemically reactive, chlorines is combined with other elements and compounds has been used to produce essential products. Chlorine was discovered in 1774, by the Swedish chemist Carl Wilhelm Scheele, he observed a greenish gas when he combined manganese dioxide and hydrochloric acid. Carl Wilhelm Scheele thought the gas contained oxygen. Carl didn’t realize that had generated an unknown chemical element. In 1810 a British scientist called Sir Humphrey Davey identified the gas as a distinct chemical element and he was the one who called it “chlorine”. Chlorine is a naturally reactive chemical element that can bond readily with any other substances to form a vast array of a useful compound. Chlorine has a melting point of 155.6 degree ( c ) and boils at 100.1 degree (c ). It may be produced by the direction of its elements at 225 degree ( c ). The symbol of chlorine in the periodic table is ( CI ) and its atomic number is 17 while it has a mass of 35.4527amu. people uses chlorine mostly in water in specific in swimming pools. This essay will talk about why do people use chlorine in the swimming pool and the disadvantages of chlorine and how it affects the human body.

Without fresh water, the internal organs such as the brain start to shut down, if the cycle continues death will eventually occur as a result of drinking too much water with a high salt content, this process is similar to plants, however it more so acts as a poison, killing the plant. However this salty water can be made drinkable and usable through means of desalination methods in order to lower the salt content of the water and in return make it safe to drink and safe for agricultural us (ie. irrigation). In order for water to be physically safe to be drinkable by humans or for use of irrigation etc., it must have a salt content of less than 0.05%. There are three main methods used for determining the salt content in water; Gravimetric (measuring total dissolved solids), Conductivity (measuring conductivity of saltwater) and titration.
