Sodium hydroxide

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…

the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of calcium chloride dihydrate is 2.8 grams. Materials: 2 Beakers (150 mL) Calcium chloride Sodium carbonate…

unknown, we needed to have a set amount of the unknown salt, and then add measured amounts of water to determine the minimum amount needed to completely dissolve the salt. The cation test told whether the unknown contained barium, calcium, potassium, sodium, strontium, lithium, copper, or magnesium. Given a chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to…

Even so, its nutritional value is essentially the same as ordinary table salt and sea salt. All three consist almost entirely of sodium chloride. Sodium is important for health in that it has benefits such as helping your muscles and nerves to function properly. As with table salt, it is important to limit your consumption of rock salt. Diets that are high in sodium are associated with high blood pressure and heart disease. Salt is thought to benefit health in a number of ways, such…

Salt, NaCl, is a chemical compound made of sodium and chloride which has been very important to humans for many years. Salt’s ability to preserve food was the most important aspect for many civilizations. It helped eliminate the problem of only being able to eat seasonal food. Also since salt was rather hard to obtain many people used it as a form of currency. Today, However salt is almost universally accessible, while being cheap and often iodized.…

King Bleach is a multi-purpose cleaner (Pental 2018, para. 2). The product manufacturer of bleach is Pental Products Pty Ltd located in Shepparton, Victoria (Pental Products Pty Ltd 2016). The chemicals contained in this product are sodium hypochlorite, sodium hydroxide and coco dimethyl amine oxide (Pental Products Pty Ltd 2016). Bleach has positive and hazardous effects on human health, in the context of household use as detailed in journal 1. In addition, the substance also has catastrophic…

Introduction Finally, a warm day after a harsh winter, so what can you expect, all the ice/snow melting and flowing into our drains or into our grass, soil, and plants (Gould, 2013). Alongside with the ice/snow melting away into our environments so is that salt that was previously used to treat the roads (Gould, 2013). Roadside vegetation can become injured or die to due to the runoff from the treated pavements (Gould, 2013). The salt used for treated pavements is usually chloride-based and is…

The purpose of this lab is to understand the effect that dissolved impurities will have on the freezing point of a mixture and what additive will affect the the freezing point the most. The freezing point of a liquid is, the point of a substance when the temperature of the solid and the liquid is equal. When water freezes the water molecules become organized and come closer together forming crystal particles of ice.When a solute (like salt) and a solvent (like water) mix together the salt…

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.…

Introduction: Hot packs work by dissolving a salt, such as calcium chloride, in water to create an exothermic reaction. When salts are dissolved in water it requires energy to break their bonds apart, but energy is also released when the ions are surrounded by the water molecules. If more energy is released than is required to break the bonds, the reaction will be exothermic and will produce heat. In hot packs the water is kept separate from the salt, and when it needs to be activated, they are…
