Salt is a unique yet very flexible substance that the earth and most inhabitants need to survive. Since early times it has been a key part of a social and cultural aspects of life. salt is even used in the bible to state the importance of the human creation from the heavenly father. Make your bed - “you search for something that can give you solace, that can motivate you to begin your day, that can be a sense of pride in ugly times.” Refer the bible with salt and the lord gives salt the ultimate…

this experiment was to reduce Camphor into Borneol and Isoborneol using Sodium Borohydride. In this reaction, Isoborneol was the major product while Borneol was the minor product. This is a reduction reaction, where the ketone on the Camphor is reduced to form two products with secondary alcohols. First, 0.25 grams of Camphor was obtained and added to a 50ml flask and mixed with 1.5 ml of methanol. Second, 0.25 grams of Sodium Borohydride was added to the reaction mixture and the reaction…

medication used to alleviate ailments such as heartburn and acid indigestion1. The ingredients that the tablet is made up of helps explain the name of the medication, the sodium bicarbonate is used to balance stomach acid, help spread the aspirin which allows the speed of absorption to increase, and reacts with citric sodium which produces carbon dioxide2. One initial observation of the Alka-Seltzer tablet and water is that when the tablet was dropped into the water, it began to fizz and make…

Synthesis of ZnO Nanostructures ZnO nanoparticles were prepared by using the following reagents : Starch solution Zinc nitrate hexahydrate {Zn〖(NO_3)〗_2 .6 H_2 O} Sodium hydroxide { NaOH) Freshly prepared ammonia solution. In order to prepare 0.01M of ZnO nanoparticles, the following steps were followed: The 0.01 M of Sodium hydroxide { NaOH} solutions in starch was prepared by adding 0.04 gm of NaOH powder dissolved in 100 ml of 3% starch solution. The solutions were stirred for 1…

triprotic acid, with different volumes of sodium hydroxide. Introduction When looking at the coefficient of balanced equations, stoichiometry is seen. Coefficients represent the number of moles, equivalent to the mass of an atom, of the products and reactants. Stoichiometry was demonstrated in this experiment to determine the relationship between the testing agents. A polyprotic acid or base is used because it is able to react with varying molar equivalents of sodium hydroxide. In…

Then, it was simply a matter of solving for the unknown metal and once we found how much the metal weighed, a quick glance at our periodic table identified the metal as sodium. The low percent error of 0.377% is indicative of the accuracy of this experiment. Possible sources of error include the unknown carbonate absorbing water during the heating and cooling process. There also may have been human error when the solid…

Salts and molecules have different properties because salts are ionic compounds and molecules are covalent compounds. Justification: Salt is an ionic compound. An ionic compound is formed by ionic bonding between ions of opposite charge. Sodium Chloride and Potassium Bromide are both salts that have an ionic compound. Both elements have the properties of salts which include soluble in water, conductive, and a relatively high melting point. Molecules and Sugar molecules are covalent compounds…

traces of salt (sodium ethanoate and sodium sulfate) and remaining soluble impurities when it is discarded (AUS-e-TUTE. 2015.) Any remaining traces of ethanoic acid and sulfuric acid is neutralised by sodium carbonate (as shown in equation 1) (Fischer esterification reaction), which is converted to soluble sodium sulfate, sodium ethanoate and carbon dioxide which is released by inverting the separating funnel, and opening the tap. Equation 1: Ethanoic Acid + Sodium Carbonate  Sodium Ethanoate…

concentration of the sodium hydroxide solution in part one of the experiment. It was known that the potassium hydrogen phthalate and sodium hydroxide should have had a 1:1 stoichiometric molar ratio. Potassium hydrogen phthalate was used as the primary standard because it is a very pure concentrated substance that can be predicted. However, the sodium hydroxide is too difficult to be measured because of its tendency to absorb water vapor. This is one area where error can be noted; at times the…

Experiment 1: Standardisation of approximately 0.25 M Hydrochloric Acid Abstract The aim of the study was to standardise a solution of hydrochloric acid with an approximate concentration of 2.5 M against sodium carbonate solution. The main steps of this experiment were preparing the sodium carbonate solution, transferring the solution into a conical flask by using a pipette, adding the bromophenol blue indicator and titrating with hydrochloric acid until the first green colour appeared. The…
