Sodium compounds

properties of Sodium Chloride, being that it is not Hygroscopic, Efflorescent or Deliquescent. Thus, based on this experiment solely, it is not ensured that the salt is Sodium Chloride as 3 other salts share this…

In this lab, the percent composition of each component in the mixture was calculated. The mixture contained NaCO, CaCO3, and sand. NaCO or salt had a physical change when it completely dissolved in water. A chemical change occurred when hydrochloric acid was added to CaCO3 or chalk because the mixture changed to a yellow green color. In order to obtain the percent composition, a filtration system was used to separate the sand from the liquid, by straining the solid with the use of filter paper.…

Obtain a piece of paper that is approximately 5cm x 10cm, and tear it into small fragments. Place the pieces of paper on a watch glass, and light the paper with a match. Observe and record reactions. Deposit a microspatula of NaCL (sodium chloride) into a test tube, and dilute the substance by infiltrating approximately an inch of water to the test tube. Let the NaCL dissolve into the water by shaking the test tube with one’s thumb over the opening of the test tube. Using a dropper, place…

Salt use on roads in winter salt is a common way to clear slippery roads. Salt lowers the temperature of the water which causes it to melt and it's one of the effective way of lower weather related collision. Using salt on road lower car accidents on highway up to 80%. However, salt used on roads causes rust on cars and environmental studies had showed that salt use for de-icing could affect water supplies, soil,and wildlife. Negative effect of using road salt The more salt that gets into…

Purpose I’m writing to propose ATC purchase an alternative traction device instead of snow chains. The current method of complying with mandatory snow chain laws is to purchase metal snow chains for the drivers to carry through the states and provinces where it is mandatory to have them in the trucks during the winter months. Situation Snow chains are cumbersome, heavy, and are often stolen when left behind for the ETLLC group to retrieve. The approximate weight of a set of snow chains is…

Summary: Put on any necessary personal safety equipment, and one person from each team should collaborate with people from other teams to create the NaOH solution. The other team members should focus on setting up the buret by rising it with distilled water as well as building the titration apparatus and preparing the HCl solution. In order to prepare the NaOH solution, first take some solid NaOH and measure its mass. Then get a 250 mL volumetric flask and fill it about halfway with distilled…

In this experiment the molarity of ammonia is calculated using the process of titration. A chemical reaction occurs when two or more substances change to form different molecules. In each reaction there are ratios between each reactants. Certain amounts of each reactant are needed to fully complete the chemical reaction. Stoichiometry is the relationship between the quantities of the reactants. An acid is a substance that reacts and donates H+ ions. A base is a substance that accepts H+ ions. An…

separation of a compound into its original elements. When trying to determine the charges of the ions in a compound, it is necessary for an outside electrical charge to be involved. The dissolving of a compound in water begins the process that helps determine which ions in a compound have the positive charge (cations) and which ones have the negative charge (anions). Solubility, how readily a substance dissolves in a specific solvent (Helmenstine, 2017), is what determines how a compound will…

this laboratory were to explore the titrations of several known acids and bases as well as observing the mole reactions of the chemical reactions that each compound undertook. The four following acids and bases were used to predict when a set amount of reactant would reach equilibrium: Hydrochloric Acid (HCl), H2SO4 (Sulfuric Acid), NaOH (Sodium Hydroxide), and Ba(OH)2 (Barium hydroxide). An unbalanced equation of each reaction was given so the balanced equation was then able to be calculated.…

acquisitions, international expansion and strategic alliances or partnerships with other firms. They reshaped company through acquisitions and had an annual organic growth rate of 3–4%. Church & Dwight pushed aggressively into consumer products outside of sodium bicarbonate-related products and into the international arena even in the early 2000s, and numerous changes were made in key personnel. They undergone a substantial transformation in the past decade largely as a result of three major…
