Sodium bicarbonate

crushed and 0.5 grams of ascorbic acid was mixed with 50 mL of deionized water to form the Ascorbic Acid Solution Preparation of NaHCO3 solution The baking soda was measured to 0.5 grams and was mixed with 50 mL of deionized water to form the Sodium Bicarbonate Solution. Experimental Concentration of NaOH M = Molarity or Concentration Known moles of NaOH divided by known volume is equal to experimental concentration times experimental volume. Experimental Concentration = 0.3 M Experimental…

acid in the stomach reaches the esophagus. One will hope to stay away from a more complex problem: GERD or gastro esophageal reflux disease (1). Bases can be extremely important to one’s health and wellness. Common bases include sodium hydroxide, sodium bicarbonate, sodium carbonate, and ammonia. They usually have a bitter taste and a slick feel. They can be used for a variety of things: NaHCO3 is an ingredient in baking soda. Not only are they used for food and health benefits, but bases are…

It simply used, a test tube, meniscus, and pipette. Then a 15 cm long sprig of elodea was placed in the test tube, after 2 cm was cut from the stem. The test tube was the filled with sodium bicarbonate solution, with 3 cm left at the top of the test tube. The volumeter stopper was then placed in the test tube. The stopper was the adjusted so the solution extended 1 to 2 cm into the pipette. The volumeter test tube apparatus was then left sealed…

In part one the Styrofoam cups and the substances that are in the cup which is distilled water and sodium hydroxide was the system while the stir rod and thermometer and the Vernier unit is the surroundings. In part two the Styrofoam calorimeter, HCl and NaOH are the system while the stir bar and the tool that is used to measure the temperature is the surroundings. In part 3 HCl, Styrofoam cup calorimeter and NaOH are the system while the temperature probe, stirring rod are the soundings 6.)…

of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent: -the rate of reaction. Controlled: - concentration of the sodium thiosulphate. - concentration of the hydrochloric acid.…

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…

in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed at the end point. This experiment is a success as two results obtained from the experiment were relatively close furthermore, an average of 21.50% of calcium carbonate obtained is close to 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…

Hair is made up of different layers and structures. It is the tough protein keratin that forms the strength of your hair, nails and the outer layer of skin. Keratin is a large molecule made up of smaller units called amino acids, which join to form a chain. The hair shaft is formed of three layers the medulla, cortex, and cuticle. The medulla is the deepest layer of the hair shaft, only seen in large and thick hairs. The cortex is the middle layer of the hair shaft which provides the strength,…

The Difference between Detergent and Soap The reason for this case study is to dissect the Difference between detergent and soap. In this case study, I will define the meaning of the cleaning agents, I will give you an introductory, I will discover how they are made, I will discover how they work, and why one cleaning agents is better than the other. This case study will be designed using the descriptive scientific method. The meanings of Detergent and Soap A detergent is a substance that cleans…
