    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

  • Chloride Ions Vs Bromine Case Study

    931 Words  | 4 Pages

    2. In the contest of these two reactions, which is the better nucleophile, chloride ion or bromide ion? Try to explain this. Bromine is a better nucleophile. The chloride ion is more polar since it is above bromine on the periodic table and is more prone to hydrogen bonding due to its smaller size. Chloride ions are worse than bromine ions for nucleophilic attack, because the chloride ions are fully solvated and are not as available to attack. This is why Bromine ion is better nucleophile because

  • Hydrogen Chloride Lab Report

    554 Words  | 3 Pages

    Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. When you add water to hydrogen chloride then it breaks down into small pieces which are known as dissolving. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because

  • Potassium Chloride Lab Report

    976 Words  | 4 Pages

    Discussion The ideal Van't Hoff factor for potassium chloride is 2, because the compound dissociates into its ions, K+ and Cl-. The greater the Van't Hoff factor means the more a compound lowers the freezing point temperature of the solvent it dissolves in. For a liquid to freeze it must form a lattice, a three-dimensional arrangement of particles that make up a crystalline solid, and the presence of solute particles interferes with the ability of the solvent particles to form a lattice. To compensate

    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

  • How Do Salt Dilutions Affect The Mass Of An Uncracked Egg

    346 Words  | 2 Pages

    salt it takes an ocean to float any substance? Well i have and i wanted to figure that out. Well the thing that makes something float is called density. Density is the weight or mass something has. The weight of salt is the ocean if it was in sodium chloride would be about 120 million tons. Which got me wondering about how much would make an egg float. This floating happens because of all the different masses. Mass is mostly based on how many atoms a substance has. Mass also helps determine density.

    filtration occurred first. The water and sodium chloride had time to sit with one another while the rest of the experiment was being conducted, meaning that some of the sodium chloride had time to completely dissolved within the water. By the time it was placed into the evaporating dish and over the bunsen burner, it was too dissolved to be recovered. If the water was added to the mixture/filtration occurred right before distillation occurred, the sodium chloride would have been able to be removed from the
