Sodium hydroxide

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,…

To begin, we put 200mL of water with one drop of green food coloring into a pie tin. We then mounted the short candle into the clay in the center of the pie tin. After, we lit the candle, waited approximately five seconds and bottled the candle. Lastly, we waited for the flame to go out and measured how high the water rose in the bottle. This process was repeated for the medium and tall candle as well. Data Table: Height of Candle Height Water Rose in Bottle Short 4cm Medium 4cm Tall 4cm…

assigned with glucose and sucrose. Diluting 1 M of sodium chloride with water made six solutions. The six solutions ranging from 0M to 1M were prepared. These 6 solutions composed of 50 mL of solutions with different concentration of NaCl. The uses of concentrations of NaCl were 0M, 0.2M, 0.4M, 0.6M, 0.8M, and 1M. Then 6 equally sized and shaped cylinders of potato were obtained and weighed initially. Then these 6 potatoes were put inside of the sodium chloride solutions. After 45 minutes, the 6…

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.…

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…
