Soluble | Phosphate PO 3-4Carbonate CO 2-3Sulfite‚ SO 2-3 | H | Soluble | Once you recorded all of the data‚ there were a few questions that needed to be answered. A. Compare your results with the solubility rules and/or solubility table in your chemistry text. I would say that my results turned out pretty close to the rules in the text book. I observed many different reactions occurring. The colors of the solutions changed from clear to purple‚ from clear to blue and yellow‚ and from clear to a milky

Chemistry of Sunscreens “Over 400 years ago‚ Copernicus declared that the sun was the center of our universe. Primitive societies in every continent have worshiped the sun as the god that provided warmth and made the crops grow” Today‚ the sun is not something we worship but something we try to avoid due to the fact that we are aware that it contains two main sources of ultraviolet radiation that is harmful to our bodies. Ultraviolet radiation (UVR) is defined by wavelengths‚ and is divided

Elisa Hofmeister Kokesh Hour 3 AP Chemistry 5-29-12 The Chemistry of Coffee Green Coffee- Before coffee is roasted‚ it is referred to as “green coffee”. The green coffee is primarily made up of caffeine‚ lipids‚ carbohydrates‚ proteins (amino acids)‚ and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase‚ and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee

Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases
