Experiment 5 Title: Mayonnaise production Objective: To determine the type of food emulsion obtained by varying the mixture sequence Introduction: A most important field of emulsion technology is that involving food preparations. Some of the oldest emulsions known to man, for example, butter, salad dressings and so on are included in this group, while the applications of emulsion theory to the baking process and to therapeutic feeding represent modern developments. Probably the most instructive…

This lab was a two week long lab called the Grignard Reaction lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of…

First, 0.25 grams of Camphor was obtained and added to a 50ml flask and mixed with 1.5 ml of methanol. Second, 0.25 grams of Sodium Borohydride was added to the reaction mixture and the reaction mixture was boiled for 2 minutes. Third, the mixture was left to cool and 10ml of water was added to it. The reaction mixture was then filtered using a Buchnels funnel and the filtered product was placed in a 50 ml Erlenmyer flask. Fourth,…

For the first double replacement reaction, barium nitrate Ba(NO3)2 is combined with sodium hydroxide NaOH. During the reaction, the mixture is cloudy and white while there are small particles of precipitation in the solution of the test tube. After the reaction, the mixture of barium nitrate and sodium hydroxide remains cloudy and the precipitation is…

the amount of time it takes for Jell-O to solidify. Since pure apple juice contains a high amount sugar, such as fructose and glucose, two monosaccharides, and sucrose, a disaccharide, it is predicted that adding this extra sugar into the Jell-O mixture will cause the rate of reaction to increase (Andrew). Because of the well-known collision theory, which states that a reaction occurs when molecules or atoms collide, it is understandable how increasing the concentration of a certain reactant is…

When you think of Rock Salt, most people will automatically think of de-icing and snow clearance, which is what Rock Salt is best for. However, did you know there are many other uses for Rock Salt as well? Such as for tire traction, weed killing and some people even make Rock Salt lamps! Here we'll take a look at some of the different uses of Rock Salt you can try out yourself. The Usual De-Icing Naturally we begin at Rock Salt's primary use, it is amazing stuff for de-icing and snow clearance…

labelled as Mix, pH3, pH6, and pH11 (Figure 2) and this plate was then placed aside for use later in the experiment. The first plate was then spotted using capillary tubes and spotting a tiny drop of each amino acid on its labelled spot, then using the mixture to also make a spot on its mark. This plate was then sealed inside the developing jar and allowed to run until the solvent reached about ¾ of the way up the plate. Once this occurred, the plate was removed from the jar, the solvent front…

250 mL beaker by filling it up to 150 ml and bringing it to a boil. Obtain 2 ml of the solution you want to test and pour it into test tube 1. To test the solution for Pb2+ and Ag+ ions, add 8 drops of 6 M HCl solution to Test Tube 1 and stir the mixture. If a white precipitate forms, then Ag+ and/or Pb2+. Centrifuge the test tube and add one more drop of 6 M HCl. If more precipitate does form, continue adding HCl one drop at a time until the supernatant (the liquid) remains…

discriminate ESO and S-NAP from their chiral impurity (R-isomer). For checking the method ability to separate the chiral impurities from the active isomers of each drug, spiking of the prepared pure S-NAP and ESO isomers with their corresponding racemic mixtures at 1%, 2% and 5% levels of the main peak was done. Method optimization was done in order to achieve sufficient resolution and detecting the R isomer at low levels of the main peak, S isomer. This was done by spiking the pure S isomer of…

This comes in handy when you have a tooth abscess. In order to create the rinse, add a few drops of tea tree oil to warm water and rinse your mouth with the mixture. Swish the mixture around in your mouth for a few minutes before spitting. Use this rinse in the morning and night in order to notice results. Peppermint Rinse Peppermint is another herb that contains antiseptic properties that ward of infection and bacteria…
