The researcher conducting this experiment is trying to find out which salt- Epsom, table salt, and sea salt- will increase the boiling point of water the most. Sodium chloride is believed to increase the boiling point of water because when salt is suspended into the water, the sodium and chlorine ions leave the “salt crystals” and mix with the water molecules. (“Why does salt… raise boiling point of water?”, 2009).
People discovered salt around 900 B.C. They would dig up salt near the Dead Sea and in South America. Salt has been important in the world’s culture for thousands of years. People used to use it to preserve meat or fish. Salt was so valuable that in several places, some would use it as money and others would trade it off for something else. (Aasen, et Al 1999).
Common salt is another word for table salt. Table salt was researched to have the most of sodium chloride and actually has ninety-nine point nine percent (“Natural sea salt - will not cause high blood pressure”, n.d.). The researcher thinks it will increase the boiling point in water the most because it has the highest amount of sodium chloride present. Common salt is said to be the most used matter in the chemical world. Salt is translucent and can create electricity if melted. It is also known to melt ice or snow because it can be added to water to create a mixture that has a lower freezing point than purified water (Aasen, et Al 1999).
Common salt is necessary in everyday lives because it carries vital substances. It also has many uses, but is found to be used in food only one percent of the time (McGrath and Travers, 1999). It is used to clear ice and snow off of roads, during the production of chlorine, in livestock feeding, to preserve foods, and to improve the taste of some foods. (Aasen, et Al 1999).
The researcher did research and found that Epsom salt is called “hydrated magnesium sulfate”. Magnesium sulfate is not to be swallowed and if it is can be harmful. It is slightly reactive, the ability to mix with chemicals, and is not flammable which means it does not catch fire easily. Magnesium sulfate is a transparent white powder that is odorless and that dissolves quickly in water. It is good to use because it is not toxic to the environment (Baker, 2008).
It was learned that changing the volume of the same substance will never change the boiling point of the substance. However having two different substances with the same volume will result in two different boiling points. The purpose of this lab was to determine if changing the volume of a substance will change the boiling point. This is useful to know in real life because if someone wanted to boil water to make pasta and did not know how much water to
The start of the book focuses mainly on how salt was first discovered and used in the ancient world.
Afterwards, we conducted crystallization to evaporate the liquid in an attempt to detect the presence of a salt. Before stating which of the potential
The hypothesis for this experiment was, If three different types of waters (saltwater, fresh water, tap water) are tested, then the liquids won’t evaporate at the same rate and tap water will evaporate at the fastest rate because it won’t have any non-volatile substances to hold it back from evaporating.
Solid A was identified to be sodium chloride, solid B was identified to be sucrose, and Solid C was identified to be corn starch. Within the Information Chart – Mystery White Solid Lab there are results that distinguishes itself from the other 4 experimental results within each test. Such as: the high conductivity and high melting point of sodium chloride, and the iodine reaction of corn starch. Solid A is an ionic compound due to its high melting point and high electrical conductivity (7), within the Information Chart – Mystery White Solid Lab there is only one ionic compound which is sodium chloride, with the test results of Solid A, it can be concluded that is a sodium chloride. Solid B was identified as sucrose due to its low electrical
The objective during this experiment was to discover the effects sodium chloride has on ice/water mixtures. More specifically how it affects the mixture’s temperature and freezing point. This was tested through seven different trials with increasing amounts of sodium chloride in each separate test. In order to conduct this analysis one must understand the meaning of the terms ‘independent’ and ‘dependant’ variable. An independent variable is a factor in the experiment that is unaffected by the other variables, whereas a dependant variable is one that will change due to other components of the experiment. In this instance the independent variable would be the sodium chloride. It is the controlled substance that does not change due to the other
Salt itself is extremely important to the body with Himalayan pink salt having a rich mineral content. That makes it a great source of salt for providing nutrients. Many families use the salt from lamps in their cooking since it can relieve a variety of skin rash problems and flu-like symptoms.
In a modern world, everyday things are used with much thought, like ice. People usually relate ice with the cubes they put in their drinks, and more notably the melting of the polar ice caps. But ice causes big problems in a large scale across the United States. Americans are faced with the problem of road ice, a cause of major road accidents in icy cities. A simple solution to this is road salt, but not many people know of its devastating effects to the environment, such as destroyed plant life, increased sodium chloride in watersheds, decreased water circulation in bodies of water, and much more (Stromberg, 2014). The purpose of this project is to research, find, and test an alternative solution to road salt by manipulating the pH of different
H_2 O (freshwater) is a well-known substance present in all organisms and all biomes on earth in various forms. Water is a substance which has a unique molecular structure that allows it to appear in different forms on earth and even in outer space. When water is in its simplest form, it appears as a liquid substance at room temperature. This discussion will address the similarities and differences between freshwater and saltwater. Although it is chemically very similar, most land organisms rely on freshwater to survive but only a mere 3% of the earth’s water is fresh.
Humans have always tended to build communities either around sources of salt, or where they can trade for it.
The last part of experiment 5, was learning about specific gravity and temperature. Specific gravity does not have any units, it is unitless. When measuring for the temperature, we used a thermometer to calculate the Celsius of the water, 10% sodium chloride, and isopropyl alcohol. The specific gravity uses a hydrometer to measure the gravity of the liquids. Using the hydrometer, to figure out the measurements we have to look at it from top to bottom. The water for specific gravity was .998 while the temperature of it was 24
To test this, we set up two experiments. The first experiment we set up had three cups. In each cup a potato slice and a different liquid was put in. In the first cup was filled with distilled water. The second cup was filled with salt water and the third was left empty.
Methodology: A plastic cup was filled half way with crushed ice and mixed with four spoonfuls of 5 mL of sodium chloride. A thermometer was quickly placed inside the cup to take the temperature and the
of salt has developed. It is important to understand why salt is used and how
Nearly every person in the world uses salt or some form of a salt as there are many salts in the world. In America alone we use a lot of salt every day we are one of the top salt using countries in the world. Salt has a part in many things in everyone’s daily lives. Salt has many important things to it such as its crystallization, what salt is and ammonia.
