Sodium chloride

solution, because it is the source of the Grignard reagent. Because the halide cannot be eliminated, the next best option is to minimize the amount of halide in the reaction. In this experiment, a small concentration of the halide is reacted with a high concentration of magnesium to ensure maximum contact between halides and magnesium. To do this, magnesium will be placed in the round bottom flask and then halides are slowly added. Another potential source of error is that Grignard reagents must…

the charges of the solvent. For instance, sodium chloride dissolves in water because the sodium cation has a positive charge and the chlorine anion has a negative charge. The water molecules also have partial charges because the oxygen is more electronegative than the hydrogen atoms, pulling electrons toward itself, producing a partial negative charge with a resultant partial positive charge on the hydrogen atoms. The charges between the sodium chloride and the water interact leading to a…

Introduction Experiment five was a two-part experiment meant to have us practice our skills and then use those skills in actual data collection and analysis. In part one we used a sample of sodium saccharinate combined with a sample of a metal halide salt, our group used copper(II) chloride. The combination of these two samples allowed for the synthesis of a metal complex. In part two of the experiment we used a procedure similar to part one in order to collect phosphorus out of a sample of…

Introduction: DNP and research question The organic compound 2,4-dinitrophenol (DNP) is a crystalline solid with the molecular formula C6H4N2O5. The molecule is soluble in water to some extent and is fully soluble in sodium and potassium hydroxide solutions. The compound can also be explosive. It is usually used in dye, weed killers, wood preserver, photographic development among other things and it has even been used as a weight loss agent. In fact, it has been claimed to be the king of the…

This week's reflection assignment consists of one video. It features Mr. Larry Potterfield (founder, and CEO of Midway USA) as the presenter. The video is titled "Gunsmithing: How to properly polish the metal parts on a Remington 700". Mr. Potterfield begins his first video by stating the objective, polishing metal parts. In his hands, he holds the barrel of a Remington 700 series rifle. It appears as if the rifle has definitely seen some cleaner days, in my opinion. This is a skill every…

disposal, in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of sodium chloride would react instantaneously and quick…

We all know that we have our own unique fingerprints but did you know that you can make sun prints? You may be wondering what a sunprint is, a sunprint is like a unique type of photo made with special sunprint paper that with the help of the sun creates a permanent image. A sunprint is formed when a chemical reaction happens with chemicals inside the paper,but before we talk about that, here is how you make a sunprint. You can make a sunprint by placing an object on a sheet of sunprint paper,…

Iodine is a metallic grey element found in the halogen part of the periodic table. In the early 1900s, many people in the U.S. were suffering from Iodine deficiencies which caused all sorts of health complications. The decision to add iodine to salt was made to remedy these deficiencies and the problems associated with them. Salt was picked as a host for the iodine, because of its widespread use and the ease at which iodine could be added. This decision did not come without a cost and today the…

What is Sodium cyanide? Sodium Cyanide is an inorganic Compound, it has a formula NaCN. Cyanide actually has a high affinity for metals which can lead to a high toxicity of the salt. Sodium Cyanide has a boiling point of 2,725°F (1,496°C) and it also has a melting point of 1,047°F (563.7°C). A common name for sodium Cyanide is sodium salt of hydrocyanic acid. Cyanide has an appearance of while crystalline or granular powder. This toxin releases a hydrogen cyanide gas which is…

Goggles are imperative for keeping your eyes safe in the lab. By wearing goggles you can protect your eyes from foreign items and substances from hurting them. Keeping goggles on at all times, when working with any chemical substance is mandatory, if any chemicals splash into the eyes, the eyes are protected by the goggles. The right clothing can help avoid many accidents in the lab. Wearing your lab coat can protect you from any chemicals coming in direct contact with your skin. Also,…
