Hydroxide

an IG2 chemistry student. He has to his disposal, in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of sodium…

reactants. An acid is a substance that reacts and donates H+ ions. A base is a substance that accepts H+ ions. An acid that donates more that two H+ ions is polyprotic. In a reaction where an acid and a base react with each other in water till no hydroxide ions remain. Molarity is the concentration of a solution. Molarity is calculable by the following formula…

cross-linker and α,α′-Azoisobutyronitrile (AIBN) were purchased from Merck (Hohenbrunn, Germany). MAA was distilled under vacuum to remove the inhibitor prior to polymerization. To clean the inhibitor from EDMA, it was washed with 10% aqueous sodium hydroxide three times, followed by washing with pure water, and then dried over anhydrous sodium sulfate. Ultra pure water used for HPLC analysis and MISPE process were obtained from a Direct.Q3 Water Purification System (Millipore Corporation, USA).…

react together and form CuCl2 and water. A very simple method that does not need much work. The next one is a neutralization reaction and a method that produces more water than the previous reaction. The reactants of this method include copper (II) hydroxide (Cu(OH)2) and two hydrochloric acids (HCl) producing a copper (II) chloride compound and two waters. There is a displacement reaction with copper (II) chloride as well. The weaker acid left over will be forced out by the strong acid in the…

The values calculated through experimentally extrapolated values compare to the the expected theoretical values of these heats with a degree of error. In most cases the values found through experiment were higher than the expected value by one or two kilojoules. This discrepancy causes a 2-5% error in the values calculated. The causes of this degree of error could be sources of errors due to the equipment and set up of the experiment. The experiment is not a perfectly isolated system which could…

When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were…

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…

Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…

Racheal A. Krasner Professor Garfield Beckford CHEM 1211 L 25 September 2015 Lab Report Concerning Acid-Base Titrations The purpose of this experiment was to recognize the procedures for conducting acid-base titrations. Each acid-base titration used one solution to analyze another; it also involved the use of an indicator, which denoted the endpoint of the titration. The indicator used was phenolphthalein; it produced a pink hue when the titrations reached their endpoints – between pH 8 and pH…

Acid-base (Neutralization) Reaction. A neutralization reaction occurs when an acid and base are mixed together. The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt. An example is…
