Sodium is an element on the periodic table with the chemical symbol as Na. Sodium, discovered by the English Chemist Sir Humphry Davy, is in the Alkali Metals group on the Periodic Table and it is a soft, silver/white color. Sodium, which is found in the Earth's crust, is important to society. Sodium originated from the Arabic word “suda” meaning headache because sodium carbonate was used as a headache remedy. It is also one of the most well-known compounds to ancient people (Newton). It is a component
Sodium (Na) Sodium has an atomic number of 11 and a mass of about 23g. It is a silvery white-metallic element classified under the alkali metals. Sodium has been known since early times and was used by the people of Mesopotamia and Egypt to make glasses. Sodium is the sixth most common element found on the earth. It is usually not found in nature but more often in compounds such as salt (NaCl). Sodium conducts heat and electricity easily. Without this element life could not exist. Each compound
Have you ever wondered why sodium is so important in our day to day lives? Sodium is one fo the top 5 most commonly used chemical compounds in our surroundings. When you close this page you will know everything about sodium! Atomic Structure: The periodic symbol for sodium is (Na), it’s atomic number is 11 and the mass number for sodium is 22.99, however this can be rounded to 23. In an atom of sodium there are 11 protons, protons are small subatomic particles that have positive charge. There are
final weight percent yield 2,4-DNP Tollen's test pathway .42g 67% positive negative oxidation of secondary OH Good Things My experiment went well. I began my experiment with .64g of 2-ethyl-1,3-hexanediol. The molecular weight of this compound is 146.2g/mol. It is converted into 2-ethyl-1-hydroxyhexan-3-one. This compounds molecular weight is 144.2g/mol. This gives a theoretical yield of .63 grams. My actual yield was .42 grams. Therefore, my percent yield was 67%
Sodium was first discovered and isolated by Sir Humphry Davy in 1807. Sodium is located in column 1 of the periodic table where all other alkali earth metals, which all of them have only 1 electron which it would happily give to another element that wants it so that it could be “happy” this then creates a positively charge atom also known as a cation. You could also find sodium by knowing its electron configuration which is [Ne] 3s1. Sodium physical properties are that it is silver in color and
Munir Chemistry Sodium is a chemical element with a symbol of Na and atomic number 11. Sodium is an alkali metal which has a color of silvery white. Sodium is a reactive element because of the shiny metal which produces hydrogen. Sodium is an essential element which can be used in humans, animals, and plants. Sodium is the sixth most common element. Sodium is the element that is used very commonly around the world such as in foods and preparation of chemicals. Sodium forms very useful compound

Sodium Thiosulphate & Acid Planning To ensure that this experiment is safe, I have taken some precautions. I wore goggles at all times, made sure not to spill any chemicals such as the acid onto skin or clothes, and to be aware of glass. I have used various different apparatus, including two measuring cylinders, one 25ml, and the other 50ml. I used a 150ml chronicle flask and a stopwatch. Here is a few diagrams of these apparatus. What I Will Vary, Not Change To Keep A Fair Test &
"The effects of calcium chloride, sodium bicarbonate, phenol red solution, and distilled water when mixed in different combinations." Introduction Calcium chloride, sodium bicarbonate, phenol red solution, and distilled water will be used in different combinations to produce different reactions. Which combination is required for each reaction viewed when calcium chloride, sodium bicarbonate, and phenol red solution were all mixed? Different combinations of materials were carried out in a plastic
Sodium Thiosulphate Rates of Reaction During this investigation I am going to investigate the rates of reactions and which changes will affect this rate. A rate of reaction is when a reactant is lost or a new product is formed during a chemical reaction. I am going to investigate the effect of concentration by mixing Sodium Thiosulphate, Hydrochloric Acid and H2O (water) until the reaction takes place and the mixture goes cloudy and the newspaper beneath the flask can no longer be read
Science lab report Aim: To find out the effect of concentration on rates of reaction using Sodium Thiosulphate. and Hydrochloric Acid. The purpose of the experiment is to see how different volumes of Hydrochloric Acid affect the rate of reaction. The reaction, which produces solid Sulfur, it will then be followed by measuring the time needed for the reaction to become opaque/cloudy. Hypothesis: I predict that the higher the volume of concentrated Hydrochloric Acid the less time it will take
Introduction:- Sodium diclofenac:- Sodium diclofenac (SDF), a sodium salt of 2-[(2,6-dichlorophenyl)aminophenyl]-acetic acid , is a potent analgesic, anti-inflammatory and anti-arthritic agent in humans, aceclofenac, has also anti-inflammatory activity, and it is metabolized to diclofenac . NSAIDs can cause adverse health effects on humans such as aplastic anemia, gastrointestinal disorders and agranulocytosis and changes in renal function. It is also used for animal medication. This drug is taken
The Effect of Acid on Sodium Thiosulphate Aim: My Aim is to see how concentration of acid will affect the time it takes for Sodium Thiosulphate to become cloudy and make a cross below it to disappear. Method: Apparatus Hydrochloric Acid Sodium Thiosulphate Distilled Water 250cm ³ Beaker- I need a beaker big enough to see the cross and although the 100cm³ would be perfect volume wise I would prefer to use a bigger one so I can fit the cross under it and also be able to pour
Softening Hard Water With Sodium Carbonate Prediction ---------- In a preliminary experiment, we discovered that adding 1g. Na2CO3 to hard water softened it slightly. We tested both tap water and distilled water with the sodium stearate and discovered that tap water was far harder than distilled water, we then tested tap water that 1g of Na2CO3 had been applied to. This solution was softer than the original tap water. The exact results were; Type of water Soap solution required
The Effect of Sodium Carbonate on Hard Water Aim === In this experiment, we aim to investigate the effect of sodium carbonate on hard water. Method ====== Firstly, 25.00cm3 of a sample of water was pipetted into a clean conical flask. The pipette was used because this measures and delivers a very accurate amount of liquid (to the nearest hundredth of a cm3, or 0.01cm3), but care had to taken to make sure it was not held by the bulge, as this could have made the amount inaccurate

PURPOSE The purpose of this experiment is to use our knowledge from previous experiments to determine the exact concentration of a 0.1M sodium hydroxide solution by titration (Lab Guide pg.141). QUESTION The question that was proposed for investigation was: Can the exact concentration of 0.1M sodium hydroxide solution be determined by titration (Lab Guide pg. 141)? BACKGROUND DISCUSSION For this experiment we used titration to standardize the exact concentration of NaOH. Titration is the process
Hydrochloric Acid, Sodium Thiosulphate Reaction Research: "Hydrochloric acid is a strong colourless acid formed when hydrogen chloride gas dissociates in water, used in industrial and laboratory processes. Hydrochloric acid is also produced in the stomach, where it initialises the digestion of proteins. Sodium thiosulphate is a white crystalline salt used as a fixer in photography and as a bleach." Encarta World English Dictionary When hydrochloric acid reacts with sodium thiosulphate
standardized solution of sodium hydroxide solution (NaOH) and to determine the concentration of given unknown sulfuric acid (H2SO4) solution. Analysis: This experiment is divided into two parts. In the first part; the standardized solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). Phenolphthalein (range 8.3 to 10.0) is used as indicator to determine whether the titration is completed. Part A: Standardization of a sodium hydroxide solution NaOH Code
