Theory A precipitation reaction is one which produces an insoluble salt as product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions could be used in this experiment to eliminate compounds while attempting to identify others. Halides react with AgNO3 to form insoluble halides. These ions form white-yellow precipitates that enable differentiation. Ag+ + NO3 - + M+ + X- = AgX + MNO3 Precipitates…

ionization of the ligand, and the sigma and pi donor/acceptor characteristics of the ligand.2 The stronger the ligand field, the larger the ∆o value and when several ligands are compared, a spectrochemical series can be produced. The spectrochemical series validates the Crystal Field Theory and Ligand Field Theory. Ligands are ordered into a spectrochemical series by observing the color of the complex in solution and by quantitative measurement of the d-orbital splitting. After obtaining UV-Vis…

A pesticide is any substance or mixture of substances designed to prevent, destroy, or control pests. The use of pesticides has been dated back to the beginning of agriculture, which was about 10,000 years ago in the Fertile Crescent. However, pesticides have not always been an organic compound. The first generation of pesticides was composed of inorganic substances, such as sulfur, mercury, lead, arsenic (calcium arsenate and lead arsenate), and ash. The modern era of pesticides was developed…

soluble in this solvent. Because the unknown solid was insoluble in acetone, Ca(NO3)2 was then eliminated as a possible inorganic compound. The flame test did not help to eliminate any possibilities for the unknown, because each flame turned orange after being dipped in the different solutions. However, as a final qualitative test, the pH test further narrowed…

program at the UCSD Skaggs School of Pharmacy and Pharmaceutical is four years in time. The first of the program is mostly focused on teaching the student pharmacists the basic of biology and chemistry. The courses include Pharmaceutical Chemistry, Histology, and Human Anatomy. The student will also take a yearlong courses of Pharmaceutics where they learn about the basics of Pharmackinetics and Dosage forms. Also students will learn the basics of Biostatics, Study design, and Pharmacy Law.…

My passion for Chemistry started in year 7, the teacher I had for science made the subject interesting and fun, so I looked forward to every science lesson I had. The areas of chemistry that interest me are inorganic and organic chemistry as you can learn a lot about how and why different substances react in different situations. I also enjoy physical chemistry, because it allows you to apply chemistry to life situations. In addition, the skills I have learnt from chemistry are varied.…

Destin Briggs Lu Jack Chem 4235 11/4/2017 Original Synthesis of Cadmium Nitrate Tetra-Hydrate Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium…

USING ICT IN CHEMISTRY EDUCATION LOKENDRA KUMAR OJHA Lovely Professional University, Jalandhar, Punjab ojha.lokendra@gmail.com Abstract There are several topics in chemistry which required computational technique to learn and use of ICT enhance learning capacity of learner as well as facilitator. The present article deals with the use of ICT in some of the topic of chemistry. We tried to overcome from routine chalk and talk method to understand the several topic viz. stereochemistries, IUPAC…

measured. This solid ideally should be mainly component Z. However after the third wash with water for component Y, the remaining solid sample seemed to dissolve completely into the water. After heating and evaporation of the water, no solid was observed at the bottom of the test tube. The same method of calculating percent composition used early was used to find percent composition of component Z. From the calculations the masses of components X, Y and Z were found to be 0.3241g, 0.3110g and…
