Sulfuric acid

Jabir ibn Hayyan was one of the greatest Muslim scientist. He is named the “Father of Chemistry.” He developed an important theory of matter. “He gained excellence in the fields of Alchemy, Astronomy, Physics, Pharmacy, Philosophy, Astrology, and Geography. He has been found to acknowledge the early works of Plato, Socrates, Aristotle, and Pythagoras, as well as, the prominent Muslim jurist Imam Jafar as-Sadiq’s knowledge on alchemy, chemistry, philosophy, and astronomy (Muslim-Academy).” He focused

diseases caused by pollution. Acid rain is any form of precipitation comprising of acidic components such as sulphuric acid, carbonic acid or nitric acid that falls from the atmosphere as rain, snow, fog, fail or dust. When sulphur dioxide, carbon dioxide and nitrogen oxides are released into the atmosphere, they are transported by wind and air currents. Hence, the two substances react with water, oxygen and other chemicals to for sulphuric, carbonic and nitric acids. The intense extraction of copper

Logs Tuesday 26/04 Today, I finished my proposal for my EEI and started researching for calculations to predict the solubility of my solutes. My decided solutes are sugar, salt and copper sulphate pentahydrate. I decided I would be using 100mL of water as my solvent due to the abundance of solutes available and that fact that 100mL is a nice, easy number to work with. I also spoke to Mrs Rach and she informed me she has a surplus of copper sulphate so I don’t have to be careful with how much I use

later, the oxides of sulfur. His studies included determining the heats of dissociation of Cl2O and ClO2 in a calorimeter and measuring vapour pressure. His research on oxides of sulfur focused on the oxidation of sulphurous acid solutions, and on the formation of sulphuric acid mists from water vapour and sulphur trioxide. Though a mechanism for removal of this mist was devised in the lab, it was not realistically applicable to

The molar concentrations of copper (II) sulfate solutions A, B, and C were 0.46 M, 1.00 M, and 0.20 M. These values were obtained by creating a calibration curve using the molar concentrations and photoresistor voltage drops for solutions 1 through 5. The quadratic equation of the calibration curve was used in conjunction with the photoresistor voltages for solutions A, B and C to predict the molar concentrations of solutions A, B, and C. The calibration curve and colorimeter valid means of estimating

1. Yes flame tests are valuable for detecting ions because each metal has a unique line spectrum, which is made up of different wavelength of light that gives off a certain color when heated. 2. The reason to soak the wood splints in distilled water is because if it wasn’t done then it would be harder to receive accurate results. By soaking the wood splints it gave us time to observe the flame color without the wood getting caught on fire. 3. If the unknown mixture were a mixture of two metals then

Questions: 1. 2H3PO4 + 3Ca(OH)2 → Ca3(PO4)2 + 6H2O 2. 2Cr + 3Cl2 → 2CrCl3 3. C6H12O6 +6O2 → 6CO2 + 6H2O 4. Na2CO3 → Na2O + CO2 5. 2VO2+ + Zn + 4H+ → 2V3+ + Zn2+ + H2O Numbers 2, 3, and 5 are all oxidation-reduction reactions. 6. The balanced chemical equation for the electrolytic decomposition of water to its elements is: 2H2O (l) → 2H2 (g) + O2 (g) 7. 2H2O → O2 + 4H+ + 4e- 2H2O + 2e- → H2 + 2OH- 8. The oxidation and reduction half-reactions may be combined to give the balanced chemical

become a very strong deactivating group. In the second part of the experiment, we will be performing the nitration of Acetanilide. We will first need to form the nitronium ion in situ by the dehydration of the nitric acid. The dehydrating agent for this experiment is sulphuric acid. The nitronium ion is an extremely strong and powerful electrophile which reacts with π–electrons involved with the aromatic ring of

(Andrei, 2012) However, since the start of industrialization in the 18th century, humans have been abusing such important features of life and created acid deposition. (The Ledger, 2014) The pH scale is composed of values starting from zero, the most acidic, to 14.0, the most alkaline. (EPA USA, 2014) While regular rain has a pH value of around 5.6, acid rain has a pH value of around 4.0. The highest level of acidity of rain ever recorded was identical to the
