An emulsion is a mixture of two immiscible liquids. Immiscible liquids, such as water and oil, are unable to mix without a third party, which in this experiment is the xanthan gum and whey powder, because of the polarity of the liquids. Because water is polar and oil is not, it is impossible for both of them to be mixed.
Purpose and Hypothesis
If we combine 0.25 grams of xanthan gum and a mixture of water and oil, then it will create a stable emulsion when shaken. The purpose of these labs are to find a stable emulsion that if left alone for fifteen minutes will remain unseparated.
Background Information Emulsions are one of the secrets of life, and if they did not exist on this planet, life would not have been able to form. Examples of

wash the ether and draw off lower layer, which is layer and to remove discarded organic substances &nbs Add anhydrous NaSO4 to ether extract until it no longer clumps together and set it aside. Acidify contents of flask 2 Litmus went from   Flask complete concentrated HCl while 2 = creamy color testing with litmus paper and cool in ice. Acidify contents of flask 1 Litmus went from   Flask complete while testing with litmus 2 = white solution paper and cool in ice.
The aim of bathing is to both grease and cleanse the skin. An excellent emollient bath may be prepared by dissolving two spoonful (dessert spoonful for child, table spoonful for adult) of emulsifying ointment in very hot water, whisking it up and adding it to the bath water.
Distilled water was used to obtain water from the purest source. As well, the highest available concentration of isopropyl alcohol was purchased to get the most accurate results. Pure vegetable oil was used. All topped by completing the trial twice, this assures the results are confirmed and are highly accurate.

== Refer to, Chemistry Lab #1 – What’s the substance? However, I changed some of procedures during my experiment, here is the changes I made in this experiment: * I only used the toothpick to place a small amount of each sample on a separate piece of paper, instead of the spatula.
When a miscible salt is completely dissolved in liquid solvent to dissociate positive and negative charged ions, then this mixture is called liquid electrolyte.
The purpose of this lab was to show us what happens to the egg (that was in vinegar), and corn syrup when you combine it. The egg that was in the corn syrup overnight was shriveled.
In this experiment, NaOH and diethyl ether are used as solvents. NaOH and diethyl ether must be immiscible with one another. They each must selectively attract the desired component from the solution being extracted. They should be easily separable from the solute being used. NaOH is a polar solvent and dissolves benzoic acid that has a high polarity, while diethyl ether is a nonpolar solvent and dissolves naphthalene that has a low polarity. The density determines the solvent position in the separatory funnel. Since diethyl ether is lighter (less dense) than water it stays on the top. Since both naphthalene and benzoic acid are soluble in diethyl ether they will not readily separate, that is why NaOH is added. When the polar solvent, NaOH, is added, benzoic acid reacts to form sodium benzoate and water because benzoic acid has a high polarity and is soluble in NaOH.
The Biological Importance of Water as a Solvent and as a Medium for Living Organisms
Journal: when i was doing my experiment the first thing i had to do was get my materials that are 1) clear drinking glass 2)¼ cup of vegetable oil
During the incubation, in an Erlenmeyer flask, 1X Tris Acetate EDTA (1 mL) and powder agarose (0.4 g) were dissolved in dH2O (49 mL). Then the solution was microwave for 2 minutes and allowed to cool to room temperature. Then SafeRed concentrate (2.5 µL) was added to the solution and it was poured into the gel box and allowed to solidify.
The solvents used in this experiment were sodium hydroxide as the aqueous layer and the ethyl acetate and unknown benzocaine as the organic phase. These phases are separated with an emulsion line which is a distinct line that shows where the aqueous and organic layers meet but do not mix. This method of separation relies on portioning the preferential dissolution of a compound into one solvent over another (2).
Firstly, an amount of 40.90 g of NaCl was weighed using electronic balance (Adventurer™, Ohaus) and later was placed in a 500 ml beaker. Then, 6.05 g of Tris base, followed by 10.00 g of CTAB and 3.70 g of EDTA were added into the beaker. After that, 400 ml of sterilized distilled water, sdH2O was poured into the beaker to dissolve the substances. Then, the solution was stirred using the magnetic stirrer until the solution become crystal clear for about 3 hours on a hotplate stirrer (Lab Tech® LMS-1003). After the solution become clear, it was cool down to room temperature. Later, the solution was poured into 500 ml sterilized bottle. The bottle then was fully wrapped with aluminium foil to avoid from light. Next, 1 mL of 2-mercaptoethanol-β-mercapto was added into fully covered bottle. Lastly, the volume of the solution in the bottle was added with sdH2O until it reaches 500 ml. The bottle was labelled accordingly and was stored on chemical working bench.
It is a transparent, colorless, viscous, oily liquid. It is tasteless and odorless when cold and have a faint odor of petroleum when heated. It is practically insoluble in 95% ethyl alcohol, glycerin and water. It is soluble in benzene, acetone, carbon disulfide, chloroform, ether and petroleum ether. It is miscible with volatile oils and fixed oils except castor oil (74).
