All of the following is true about crystallization EXCEPT * A common practice is to dissolve the organic compound in heated mixture of solvent and adsorbent. In separating components of mixtures by crystallization, a solvent must be chosen which dissolves the compound to be crystallized at an elevated temperature and allows the solute to crystallize on cooling Filtration is usually done while the solution is kept hot in order to promote crystallization. Animal charcoal is a solid adsorbent

Fresco Painting is a mural painting technique that involves painting with water-based paint directly onto wet plaster so that the paint becomes an integral part of the plaster. The word fresco is an Italian for “fresh”. Fresco painting makes use of chemical reaction that causes color pigment to crystalize within the plaster as it dries. As the plaster dries, carbon dioxide in the air turns the lime to calcium carbonate, crystalizing the pigments. The color then becomes part of the plaster itself. The process of forming a carbonate is sometimes referred to as “carbonation”, this term usually refers to the process of dissolving carbon dioxide in water. Calcium carbonate and natural pigments make the medium of Fresco the most environmentally safe medium. Only pigments that resist the action of lime can be used. The pigments are usually earth color. Frescoes have been painted for hundreds and hundreds of years. What is the role of carbon dioxide in air in Fresco Painting? What type of…
Is it possible if you can do this and show how you did it please?
a sodium chloride/ calcium chloride mixture was found to produce 0.16g of precipitate after dissolving in 60mL. A reference if 0.4g of calcium chloride in 60mL produced a precipitate with a percent yield of 73%. What would be the mass of calcium chloride in the mixture?
When a nonvolatile solute such as ammonium sulfate is dissolved in a solvent like water, one of the observed effects is an increase in the vapor pressure of the solute. B scattering of light beams by the solute particles in the solution. an increase in the freezing point of the liquid. a decrease in the vapor pressure of the solvent. a decrease in the boiling point of the liquid.
the solubility of any organic material in a given solvent is due to the intermolecular forces present between the solvent and solute, hexanes (the alkanes isomers of C6H14) are rarely used for extraction purposes. What is a good reason for this experiment?
2. You have a solution that contains 4.0g of oxalic acid dissolved in 100 mL of water. This solution is placed in a separatory funnel, and then 100 mL of diethyl ether is added to the separatory funnel and an extraction is performed. (Diethyl ether and water are immiscible solvents.) Use the following constants to calculate how much oxalic acid is in each solvent after the extraction. Solubility of oxalic acid in water = 9.5 g / 100 mL Solubility of oxalic acid in ether = 16.9 g/100 mL
