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

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending

is suitable for horticultural crops. Potential for horticultural development is very bright along with canning and processing industry as this district produces huge quantity of quality pineapple‚ oranges and ginger through purely organic method as use of agrochemicals is virtually non-existent. However‚ all the tribes of this hilly district are mainly dependant on destructive slash and burn method of cultivation or Jhuming and in the process forest cover has been largely denuded and ecosystem

CHEMISTRY PROJECT INVESTIGATORY PROJECT ON: CAFFINE CONTENT OF TEA About caffeine: Caffeine is a naturally-occurring stimulant‚ found in several plants. Caffeine is water soluble‚ and is extracted into the brewed cup when preparing tea‚ coffee‚ or other caffeinated drinks. The most well-known plants containing caffeine are the tea plant‚ Camellia sinensis‚ coffee‚ yerba maté‚ and guayusa. Although tea is known to have a number of health benefits‚ heavy caffeine use is known to have unpleasant

Besides the other topics involved in Asbestos‚ they have chemicals and chemistry involved. “Naturally occurring asbestos can be found most abundantly in and around Humboldt County‚ in areas of San Benito and Monterey counties‚ and in western El Dorado county” ("Naturally Occurring Asbestos"). Asbestos is not a human substance or a chemical‚ but it is made out of stone. There are a group of six naturally occurring silicate minerals that is inside found in rock and soil which are: amosite (Fe7Si8O22(OH))2
