Sodium Essay Topics

Salt Paper

In its mineral form sodium chloride, NaCl is known as common salt. It is important because it is essential to the health of human beings and of animals. For domestic use it is fined down to what is known as table-salt and small quantities of other chemicals are added to it to keep it free-flowing… View Article

Sodium acetate

Claim: Relatively pure isoamyl acetate was isolated by elimination reaction as compared to the SN2 reaction. Evidence1: A flask containing isoamyl bromide (6 ml, 0. 050 mole) and potassium acetate (6 g, 0. 05 mole) in 10 ml of dimethyl formamide was positioned in a steam bath and then mounted on a magnetic stirrer. The… View Article

Beta-Galactosidase and Western Blot

1. EMG 9 and EMG 26 contain strain _lac-_(I- Z+ Y+) and strain _lac -_ (I+ Z- Y-)respectively.Three genes huddled together on the chromosome are required for two strains of _E.coli_ to utilize lactose.Consisting of three genes, namely, _lacZ_, _lacY_ and _lacA_, the _lac_ operon orderly handles these genes to code specific enzymes necessary for… View Article

Foam Stored Pressure Fire Extinguisher

Introduction The fire extinguisher is a portable device used to put out fires of limited size. Such fires are grouped into four classes, according to the type of material that is burning. Class A fires include those in which ordinary combustibles such as wood, cloth, and paper are burning. Class B fires are those in… View Article

This is a chemistry lab report

Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid, potassium acid phtalate (HKC8H4O4, abbreviated… View Article

Investigating stoichiometry

In this experiment we are going to get a better understanding of chemical stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct… View Article

Separation of a mixture of solids

The Discussion of this experiment began with discussing how many materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances, it all depends on whether you can separate the substances… View Article

Impure Sodium Carbonate

Introduction: To determine the total amount of carbonate in unrefined sodium carbonate, soda ash, a titration is done using a standardized solution of HCl. Aqueous HCl is a strong acid and therefore almost completely disassociates into H+ and CL-. Therefore, when HCl is used in a titration, the H+ is the titrant. Carbonate in aqueous… View Article

Microscale Techniques

1. NaOH is a very corrosive chemical and contact with it can cause burns to body tissue and possible eye damage. Can irriate the lungs and can cause permanent lung damage. also contact with water can generate enought heat to ignite combustibles. 2. In your own words, briefly explain the terms below. Copied answers will… View Article

Star Apple (Chrysophyllum cainito) as an Antiseptic Mouthwash

a. Background of the Study As an effective mouthwash is one that does not only make the breath fresh but also serves as an antiseptic. It should not simply mask the effective mouth odor caused by excessive activity of anaerobic bacteria inhabiting the mouth. There is a need to prevent the increase in the population…. View Article

Homemade Lava Lamp

My science project is on the No Light Lava Lamp. I will record what happens when I mix vegetable oil and water in an empty water bottle. Most materials are classified into two different categories in relationship to the way they mix water. Hydrophobic substances are chemically unable to mix with water (the word hydrophobic… View Article

Identification of an Unknown Organic Acid

Abstract Identifying this organic acid was an extensive task that involved several different experiments. Firstly, the melting point had to be determined. Since melting point can be determined to an almost exact degree, finding a close melting point of the specific unknown can accurately point to the identification of the acid. In this case the… View Article

Stoichiometry of a Precipitation Reaction

Abstract: In this experiment Stoichiometry of a Precipitation Reaction, the main objectives were to use stoichiometry to calculate the theoretical yield of CaCO3 that precipitates from the reaction between Calcium chloride, Dihydrate and Sodium carbonate, and then compare that value to the actual yield. In order to do this accurately, we must be able to… View Article
