Sodium Chloride Lab Report

Procedure- The procedure for this lab includes many simple steps and a few different things we are testing. Our first Procedure was to combine water and salt to see what kind of reaction it would make. First we fill the graduated cylinder with 100 ml of water. We then measured 1.0 grams of table salt on a balance to get an accurate amount. After, we took the measured amount of salt and poured it into the water filled beaker. Lastly, we watched and recorded the reaction.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Sodium Chloride is added to the ice to lower the melting point of the ice, which is called ionic dissociation. The sodium chloride is added to the ice in the larger bag in order to keep the dissolving ice from becoming room temperature. Sodium chloride keeps the ice/ slush at a low temperature that allows the ice/slush to start chilling the cream and milk which is located in the smaller bag. The freezing point drops to about -10 degrees Celsius. This allowed the ice/ slush to remain cold at a low temperature. The sodium chloride prevents hydrogen bonds and keeps the water molecules solid. This is called freezing point depression. This is one of the colligative properties of science. Without the temperature dropping, the ice/ slush would not remain cold and crystals would not be able to form in the smaller bag. The crystals create the ice cream’s texture.

October 17, 18, and 19, samples were collected from multiple sites along the BSR. The class was split into groups, and samples were collected from seven separate locations along the river and WWTP. There was also a sample collected by the S which is located between sites four and five. For each of these sites, there were ten groups from other labs that also collected a sample from the BSR. At site two of the river, the location included multiple sources of possible contamination. A drainage site was located 200 yards upstream, along with a small PVC drainage pipe next to the collection site. Not only was there drainage running into the river, the site was under a bridge, and contained other trash scattered throughout the area. The

The wet, crude product was placed into the 50 mL Erlenmeyer flask. Small amounts of CaCl2 were added to dry the solution. The flask was sealed and the mixture was swirled and left to settle. Once

The main goals of the experiment are to be aware of the ionic compound by comprehending of the principle of solubility. Then to be acquainted of the solubility rules because it’s important to design combination of a various compounds . After that, detach the solid product to see the final solution. However, in this experiment we have been used several material, such as, BaSO4, Zn(OH)2, Al(OH)3, and NaCl to discuss what will be the final compound. On the other hand, now we can define the Ionic compound, as a common, yet distinctive type of a chemical compound, and it’s a compound, which created by ions bonding with each other through electrostatic forces. However, the acid base reaction includes the transfer of hydrogen ions; in general, we

The purpose of this lab was to separate a mixture of iron, sand, and salt into each of its individual compounds or elements. The iron had a magnetic property so the group was able to separate the iron shavings from the mixture using a magnet. Then the group used filtration to separate the sand and salt. When the mixture was filtered, salt water went through the filter and the sand stayed in the funnel, this lead to the conclusion that particles of sand are larger than particles of salt and water. Then the group distilled the salt water mixture so that the water evaporated and the salt was left, this lead to the conclusion that the boiling point of water is lower than the boiling point of salt. The group had hypothesized that the mixture could

Sodium Iodide is not an electrophilic source for Iodine because Iodine is the least reactive of all the halogens, and it itself does not serve as a base, due to its positive charge. This means that Sodium Iodide needs an Oxidizing agent to make it a strong electrophile.

Ionic compounds and covalent compounds have many similarities and differences. Ionic compounds are only formed with metals and non-metals. Covalent compounds are formed with non-metals. Ionic compounds have an overall neutral charge, but covalent compounds don’t have charge. Ionic compounds are formed when non-metals take electrons from metals. This gives both of them noble gas configuration. Covalent compounds are formed by two non-metals sharing their unpaired electrons, so they can mutually have noble gas configuration. What properties do compounds form when forming ionic and covalent bonds?

2. When 2.00 g of NaOH were dissolved in 49.0 g water in a calorimeter at 24.0 ˚C, the temperature of the

In a test tube, 0.5mL of the sample will be added with 0.5 mL of water and shaken vigorously. Take note for its solubility by parts (0.5mL is one part). Keep adding parts of the solvent until the sample is soluble. If not, add until ten parts of the solvent and determine its solubility. To separate test tubes, water will be replaced with ethanol, chloroform, ether, and acetone as solvents. Same procedures were

The purpose of doing this lab was to apply the knowledge of chemical reactions to identify an unknown substance. Research was done prior to doing the experiment to provide a basic understanding of the chemical reactions occurring. There are two elementary aspects a chemical solution. First, there’s the reactant. The reactant is the substance added that reacts with another chemical, after the chemical reaction has run its course, what is left is called the product. There are about seven ways to tell if a chemical reaction has taken place; a few of which include color change, precipitate, the formation of gas, and temperature change. In this particular experiment, the question that was being investigated was: What is the unidentified chemical substance? The hypotheses made was: The unnamed chemical is Calcium Chloride considering each are clear liquids.

Patient #1 will need several lab and diagnosis test ran on the current medication list. A CBC and culture & sensitivity test is needed for the Vantin to determine if still needed for bacterial infection. Potassium level along with renal function, bicarb and pH level should be monitored for mineral and electrolyte replacement of potassium Chloride. Furosemide (Lasix), which is a diuretic, is being administered 40mg PO daily. Electrolytes, renal function, hepatic function, glucose levels along with uric acid level should be checked before therapy begins. Also, check for decrease in potassium, sodium, calcium and magnesium. Patient #1 is on several benzodiazepines Librium 25mg Q8h, Ativan 1mg every 1-2hrs orally as needed. And Serax 15mg
