The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other

(Date) Summary of chemistry lab report Introduction The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited amount of product can form from given amount

To what extent does varying the Sodium Chloride concentration impact the mass change of Solanum tuberosum cubes? Katie Hynek 12/11/15 Personal Engagement: Every Thanksgiving my aunt and grandma switch off making mashed potatoes and every year they use the same recipe. This year it was my aunt’s turn and when we went to eat the mashed potatoes they were super salty. After thanksgiving dinner that year I became interested in figuring out how the using the same recipes the outcome could be so different

be accomplished in one of several ways. An esterification occurs when an alcohol and a carboxylic acid are reacted in the presence of a mineral acid catalyst‚ such as sulfuric acid. Because these reactions result in an equilibrium mixture of both products and reactants‚ the reaction conditions must be

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina dissolved in cryolite. Cryolite is sodium aluminium fluoride (Na3AlF6). A solution of alumina in cryolite melts at about 900 °C and electrolysis is done at about 950 °C. Extraction of Aluminium - Electrolysis Cell
