vegetable oil had a primary fatty acid called linoleic acid‚ which was evident during the saponification reaction. The simple soap did appear to be a good emulsifier because the soap did dissolve in the mixture of mineral oil and water. In hard water the calcium and magnesium did loose their effectiveness and became insoluble in the solution. When magnesium was added to acidic water‚ the salt was converted to a fatty acid‚ and was also insoluble. Background: The purpose of this experiment is to demonstrate

Abstract: A solution of cyclohexene‚ aqueous sodium hydroxide‚ and benzyltriethylammonium was used to synthesize 7‚7 – dichloronorcarane by the following reaction: + CHCl3 + OH - H2O + + Cl - After completion of the experiment‚ the percent recovery was calculated to be 46.21% Introduction The purpose of this experiment was to form 7‚7-dichloronorcarane by means of carbene trapping. Cyclohexene‚ aqueous sodium hydroxide‚ and benzyltriethylammonium chloride were used to synthesize

Introduction An alkyl halide is a derivative of alkanes. Alkanes are hydrocarbons with a functional group C-C. The hydrogen atom is then replaced by a halogen (F‚ Cl‚ Br‚ I). Therefore‚ alkyl halides are compounds that have a halogen atom bonded to a saturated‚ sp3 hybridized carbon atom. These could be classified according to the number of alkyl groups attached to the carbon that is bonded to the halogen atom. A methyl halide does not contain any alkyl group‚ a primary halide has one alkyl group‚ a secondary

against short periods of drought or to allow water supply to be maintained during transitory pollution incidents in the source river. 4. Pre-conditioning – Water rich in hardness salts is treated with soda-ash (sodium carbonate) to precipitate calcium carbonate out utilising the common-ion effect. 5. Pre-chlorination – In many plants the incoming water was chlorinated to minimise the growth of fouling organisms on the pipe-work and tanks. Because of the potential adverse quality effects (see

expected‚ which allowed the remaining liquid‚ containing either barium chloride or calcium chloride‚ to be separated and set aside into another test tube to be tested in Part B. The precipitate could then be further tested by mixing in potassium chromate to see if a yellow precipitate would form. A yellow precipitate would indicate that lead had bonded with chromate‚ which was the case for unknown solution
