    The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder

    concentration of Sodium Chloride (NaCl) solution affects the volume of the gases (Oxygen gas and Chlorine gas) at the anode during the electrolysis of sodium chloride solution. In my previous chemistry classes, I have learnt that concentration affects the majority of the gas produced at the anode. This made me wonder, how does the ratio of oxygen gas to chlorine gas produced at the anode vary at the electrodes. This made me formulate the research question: How does the concentration of Sodium Chloride solution

    of each solution according to its concentration. Assuming that the density of each solution is approximately 1 g/mL, the mass of each solution will be 600 grams.(mass of solution=volume of solutiondensity of solution) In order to calculate the sodium chloride mass required for each solution use the following formula: mass of solution=mass of NaCl 100concentration of solution. For the solution of NaCl 5% are need 30 g NaCl and 570 mL water; for the solution of NaCl 8% are needed 48 g NaCl and 552 mL

    one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant. For example, from our experiment in the lab, we observed mass of the mixture of aqueous Sodium Sulfide and aqueous Zinc chloride turned white color. After the filtration, and all the water was evaporated, we measured the mass very close to what we had started at the beginning. The error in mass occurred because of the remained residue (solute) in the beaker

    I. INTRODUCTION This report discusses an experiment, the objective of which was to determine the classification of six known chemicals: sodium nitrate, barium chloride, silicon carbide, naphthalene, urea, and antimony and two unknown chemicals XIa and XIb. Since each type of chemical (ionic, molecular, macromolecular and metallic) has its own set of properties, by testing these properties and finding them out for each chemical, it was possible to classify them. The properties tested during this

    DESCRIPTION  A simple reaction, followed by isolation of the desired product from the solution, will illustrate a typical application of extraction.  Some organic acids are liquid and are soluble in water as indicated. The sodium salts of these acids are ionic compounds that are also very soluble in water. If an aqueous solution of one such salt is acidified with a strong mineral acid, the much weaker organic acid is produced.  The weak organic acid is largely un-ionized in the aqueous solution

    Does table salt, sugar and pepper effect the time it takes to melt an ice cube? Introduction In areas around the world, where there are blizzard conditions, getting from one place to another is quite a problem as snow blocks the roads, railways and prevents aeroplanes from entering and exiting the country. In these countries, how are they able to melt the ice so that the road is clear for use? If you live or have been in a place that often has snow in winter, you may have seen truckloads of salt

    Finding the Formula of a Hydrate – Lab Report (DCP, CE) Introduction and Overview: A hydrate is a chemical that has water molecules loosely bonded to it. The water molecules are not actually part of the formula, so the formula is written slightly differently. An example would be CaSO4 . 3H2O. This chemical would be called calcium sulfate trihydrate. When finding the mass of this chemical, you find the mass of the calcium sulfate and then add 3 times the mass of water to it. (40.08 + 32.066
