Sodium chloride

trials were low due to the errors that occurred throughout the lab. Another topic that relate to this lab was single replacement. In this experiment, solid magnesium and hydrochloric acid solution underwent a single replacement that yielded magnesium chloride and hydrogen gas. Additionally, the ideal gas law was used in this experiment to find the moles of hydrogen gas. Another topic that relate to this lab was the limiting reagent. The limiting reagent in this experiment was the magnesium.…

Once the solution was stirred, the cap was placed on the reaction vessel, which was put into the microwave for heating. Next, 40mL of 3M sodium hydroxide was chilled in an ice bath, and then the extraction apparatus was constructed. Once the microwave was done, the vessel was rinsed with 5mL of water, which was poured into the separatory funnel. Then cold sodium hydroxide was then added portion wise to the separatory funnel and the funnel was swirled. Next, 10mL of dichloromethane was added to…

Grilled Salmon There a variety of methods you can you to cook Salmon; however my best method is to grill it. The natural oils found in the Salmon help it to retain the moisture and also develops some crispiness on the outer side of the fish. Ingredients - 1 ½ pounds of salmon fillets - Lemon - Salt (to taste) - ¼ cup of olive oil - 1/3 cup of water - 1/3 cup of soy sauce - Garlic powder (to taste) Directions You just need a few easy steps to your ideal Grilled Salmon Prep time- 15 minutes Cook-…

This Density of Copper lab was an experiment, which helped to show how to calculate the density of copper while comparing the results of the density of water. While doing this experiment we had to remember the density of water, which is 1g/cm3. However, before trying to find the density we needed to make sure we had the mass and volume. We were given two ways to help find the density of copper and a beaker. I had to first measure the mass of the copper by picking it up and gently placing it in…

The mixture of salt and sand is heterogenous and their physical properties can be used to separate it. To separate sand and NaCl it must be diluted with water then filtrated using filter paper. The residual water is full of dissolved NaCl since NaCl is water soluble. The NaCl can dissolve in water because of water’s emergent property; versatility as a solvent. Because water is polar, it can break apart other molecules until the molecules are bonded with water. To separate the soluble NaCl from…

observed, this might be due to the Bunsen burner not being completely cleaned or the sodium not being completely pure. The observed colours match those of the spectrum, and can be accepted as true. The observed colour for lithium was a dark red colour. Lithium’s emission spectrum consists of purple, blue, cyan and red. Few darker specks of blue were observed, possibly from the same substance that made the specks, when sodium was burned. The observed dark red colour fits the emission spectrum of…

The Effect of pH Level on the Amount of Brine Shrimp Hatched By: Maggie Lazaroski and Paloma Diaz Period 1, January 8 2014 Introduction Paragraph In this experiment, we will be using brine shrimp to measure the effects of pH on the survival rate of invertebrate creatures. We will use white vinegar and baking soda to alter the level of pH, the white vinegar to make the pH level higher and the baking soda to make the pH lower. We will be feeding the shrimp yeast, which is completely…

other compounds. After performing the four anion tests, a positive identification was able to be made showing that the unknown compound contained a chloride ion since a white precipitate was formed from the reaction (Table 1). The sulfate, nitrate, and carbonate tests all yielded negative results when no precipitate was formed. The reaction of the chloride anion is as follows: Cl- + AgNO3 -->…

dissolved in water and the chloride ions were precipitated using silver nitrate which produced silver chloride. The silver chloride was then separated by filtration techniques and through this the amount of chlorine in the original salt was able to be calculated. It is expected that the chlorine percent will be around 55.95% because that is the accepted value of chlorine content in the unknown salt. Theory: In this experiment the unknown salt was precipitated as silver chloride through the…

When both solutions are mixed a white precipitate (Calcium Carbonate) is formed alongside Sodium Chloride. A clear colourless liquid is observed as the white precipitate is filtered through the filter paper.…
