Lauric acid is mainly used in the manufacturing of soaps and other cosmetics. In scientific laboratories, lauric acid is often used to investigate the molar mass of unknown substances via freezing-point depression. In industry, lauric acid is used as an intermediate and as a surface active agent.
Contributing activity / technique for the environment Name of activity / technique: Direct application of plant protection products (granules or treated seeds) containing co-formulants to soil (indoor or outdoor) Contributing activity / technique for the environment Name of activity / technique: Direct application of plant protection products (granules or treated seeds) containing co-formulants to soil (indoor or outdoor) This lab uses mostly non-toxic lauric acid combined with a small amount of benzoic acid which is only slightly toxic. The chemicals can be reused from year to year. Time 50 minutes for data collection 50 minutes for processing data Objective 1. To calculate molar mass of a solute from freezing point depression. 2. Jun 16, 2016 · Generally, MCT Oil contains 100% Caprylic Acid (C8) or 100% Capric Acid (C10). In some occasions, a combination of both can be found. However, Caproic Acid (C6) is not found in MCT Oil, and Lauric Acid (C12) is also often missing or only available in small quantities. Using Freezing-Point Depression to Find Molecular Weight Formal Lab Report Purpose: The purpose of this lab is to be able to use the freezing point of a substance to find the molecular weight of it. To do this, we will use the Logger Pro program to obtain the freezing point of lauric acid and a solution of benzoic acid and lauric acid. Lauric acid is a long chain fatty acid of formula C12H24O2 with melting point of 44 C. Stearic acid is another long chain fatty acid of formula C18H36O2 and melting point of 69.6C.
Dec 14, 2011 · Part of NCSSM CORE collection: This video shows the collection of data for the freezing point depression of lauric acid and the determination of the molar mass and molecular formula of an unknown ... Lauric Acid 99% FGK ... In bulk, store at about 5-10°C above melting point or at ambient temperature. ... Freezing Point : No data available .
Lab 14: The Cooling Curve & Heating Curve of Lauric Acid Objective: 1. observe the freezing and melting behavior of lauric acid 2. construct a graph of the cooling curve for lauric acid 3. interpret the freezing point and melting point from a graph Background: In any pure substance, changes of physical state occur at constant, discrete LAURIC ACID is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. and lauric acid in the mixture and finding the freezing point depression, ∆T, the equations above can be used to find the formula weight of the unknown acid. Look up the melting point (freezing point) of pure lauric acid (also called "dodecanoic acid"). Part I: Freezing Temperature of Pure Lauric Acid 1.
