Megan Ly Chemistry 231L February 20, 2013 SOLUBILITY Purpose: To better comprehend solubility behavior by investigating the solubility of various substances in different solvents, looking at miscible and immiscible pairs of liquids, and observing the solubility of organic acids and bases.

In this lab, we observed the solubility of substances 1-4, which is a physical property of matter. Physical properties can be observed without changing the matter into something new. Solubility is also a characteristic property--properties that do not depend on the amount of the substance and are used to identify matter. When we measured solubility, we created a mixture with our substances and the 100 mL of water. A mixture is two or more substances that are physically combined. We created a mixture
The definition of solubility is a property of a solid, liquid, or gas solute to dissolve in a solid, liquid, or gas solvent. The two parts of a solution are the solvent and the solute. When a solute is dissolved, particles of the solute leave each other and become surrounded by particles of the solvent. In this lab, we tested stirring speed, concentration, particle size, and temperature and their effect on solubility. The question was, “How can you control the rate at which certain salts dissolve
Solubility Lab Report The purpose of this lab was to demonstrate the solubility of compounds created through reactions between certain dissolved substances. The solubility or insolubility of these compounds creates a visual demonstration of solubility rules. To obtain the data, the molar mass of each compound was calculated, and divided by 100 to determine the mass (in grams) needed. The compounds used in the lab include KNO3, Na2CO3, NH4Cl, NaOH, Pb(NO3)2, K2CrO4, AgNO3, CoCl2, Ba(NO3)2, CuSO4
Jacinta Houng Comparing the Solubility of Chemicals in Water “Water is known as the “universal solvent” because so many different substances dissolve in it and we rely on this for many of our daily needs.” Introduction: Water is known as the ‘universal solvent’ as it is capable of dissolving a variety of different substances and dissolves more substances than any other liquid. However the ability to be soluble depends on a substances polarity and bonding. This then contributes to the various ways
-chemist understands solubility as a measure -a chemist would say that solubility is the max solute that can be dissolved in the solvent until it reaches equilibrium -when the solution reaches equilibrium, there can be no more solute added to the solvent: it won 't dissolve anymore, it will just rest at the bottom as residue -the chemical formula of salt is NaCI -1 ATM is standard air pressure for earth -the unit for solubility of water it for ex: 357.00 g/L -when the solubility is put in the solvent
The experiment contains two procedures: the solubility tests, and macroscale recrystallization of chosen solutes and solvent. The solubility tests were performed with all the solutes, which were phthalic acid, naphthalene, anthracene, benzoic acid, and resorcinol. The three solvents were water, methanol, and acetic acid. Solubility tests were carried out at both low and high temperature conditions, depending on the substance. The most efficient pair was acetic acid and anthracene, which was chosen
NaCl or sodium chloride salt has one of the highest levels of solubility in water due to its ionic bonds, which easily breaks apart in a polar solvent meanwhile, sodium chloride is not soluble in hexane because of the structure and polarity of hexane that is non-polar. Thus, when NaCl is put into hexane, the charged particles and the non-polar particles would stay altogether resulting in no mixing or dissolution. Naphthalene is non-polar covalent solute therefore it dissolves in non-polar solvent
could affect different patients when developing these drugs. Solubility is one of these properties, and it is the ability of a solid, liquid, or gaseous substance to dissolve in a solid, liquid or gaseous solvent, and it is critical to absorption into the body. In drug discovery over the years, the number of insoluble drug candidates has increased recently, with almost 70% of new drug candidates showing poor water solubility. The solubility of a substance fundamentally depends on the solvent used, as
What is solubility? Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. (Science Daily, 2014) Solubility occurs around people throughout their everyday life, and is exemplified through their food and drinks, and even the air that surrounds them. Solubility is a complex idea that can be understood in a simpler form, i.e., having hot coffee and adding sugar to it. It appears that the hot coffee melts the salt, but deeper beyond the
