Discussion The main purpose of this lab was to synthesize four soaps and two detergents and determine which one would be the best for an environmental group to use in the event of an oil spill.1 To complete this task‚ five subgoals had to be achieved first. To find the solubility of the fats‚ oils‚ soaps‚ and detergents‚ each of them were placed into different solvents to see if they dissolved. None of the oils and fats were soluble in water (H2O)‚ sodium hydroxide (NaOH)‚ or hydrochloric acid

Objective The purpose of this lab is to determine the particle size distribution of the fine and coarse aggregates by sieving. Equipment and Material Balance‚ sensitive to within 0.1% of the weight of the sample to be tested Standard sieves for grading of fine aggregates- 4.75 mm‚ 2.36 mm‚ 1.18 mm‚ 300m‚ 150m (# 4‚ 8‚ 16‚ 50 and 100) Standard sieves for grading coarse aggregates- 1 ½ in.‚ 1 in.‚ ¾ in.‚ ½ ‚ 3/8 in.‚ 4 in‚ plus a 4.75 mm(#4 sieve) Fine (0.5 Kg) and coarse (2 to 20 Kg depending

Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

and standardized base solution‚ and through titration. The purpose of titration was to determine the concentration levels of the commercial products being used. Methods and Materials Week One: the experiment started off by preparing 250mL of NaOH solution. About 0.5 grams of NaOH were measured and then inserted into a 250mL volumetric flask. Once the NaOH was in the flask‚ it was then filled up to the 250mL line using deionized water. After the water was put in the flask‚ the solution was then

Purpose: To observe epithelial tissue by using a microscope to compare prepared slides. Introduction: Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as

of acetic acid. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add acid solution to basic solution to produce water and salt this activity is called titration. It involves carefully adding one solution to another until chemically equivalent amounts react. Vinegar is a solution of a weak acid in water. This acid will react with the base sodium hydroxide in a 1:1 molar ratio. If a solution of NaOH of known concentration will used titrate vinegar‚ it is possible

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

ELECTROLOYSIS OF WATER: DETERMINATION OF THE FUNDAMENTAL ELECTRONIC CHARGE PURPOSE: The fundamental electronic charge of water will be determined. A system of collecting the formation of H2 and O2 using two inverted glass collections tubes and a 1-L beaker filled with water will be setup. An electrolyte (H2SO4) will be added to water to make it an electrical conductor. A small amount of electricity will be applied to the water (roughly 400 mA) to oxidize the oxygen and reduce the hydrogen
