PPT-The thermodynamics of the solubility of borax

D etermination of ΔH and ΔS Borax Borax has the formula Na 2 B 4 O 5 OH 4 8H 2 O B 4 O 5 OH 4 2 is the tetraborate anion Borax is a weak base and reacts with acid. A Physical Property. A . Definition of solubility:. . A measure of how much solute can dissolve in a solvent at a given temperature. .. What is a . solvent. ?. A substance that dissolves another substance.. (. Ferb. , I know what we’re . gonna. do today). Crystallization. Crystals are forms of solid matter that have ordered structures. Crystals often appear in a clearly geometric shape and many familiar things are crystals, including diamonds, graphite, salt, sugar, caffeine, and snow. . Awesomely gross stuff you can make at home. Gak. . (Slime). EXPERIMENT. Empty . the entire bottle of glue into a mixing bowl. . Fill the emptied glue bottle . with warm . water, replace the lid, . and . 2. . Know and be able to account for the trends in reactivity with water. , the relative solubility of the hydroxides and sulfates. . The Trend . Hydroxides increase in solubility down the group.. Sulfates decrease in solubility down the group.. Chapter 18. Is . AgCl. soluble or insoluble?. Dissolution Reactions and . K. sp. Expressions. AgCl. (s). Mg(OH). 2. (s). Ca. 3. (PO. 4. ). 2. (s). Standard Reaction Types:. Determining . K. sp. Experimentally. Mixtures. Solutions are a type of mixture, so to understand solutions, first we have to know what a mixture is…. A . mixture. is a combination of two or more substances. Each substance keeps it’s own properties, even though it is mixed with another substance. They . Materials. Plastic cup. Popsicle stick. Pipe cleaner. 200 mL water. 25 g Borax. Procedure. Shape pipe cleaner into an ornament. Make sure the shape will not touch the sides or bottom of the cup.. Add 25 g of borax into cup. Science Experiment. (Crazy Putty). •2 containers (1 smaller than the other, preferably a film canister). •Water. •Food . coloring. •PVA glue (a type of white glue also known as Elmer's glue). Gout primarily affects adult men over the age of 40. . Attacks of gout may occur when the concentration of uric acid in blood plasma exceeds its solubility of 7 mg. /. 100 mL of plasma at 37 . °. Question. How does changing the temperature of the solvent effect the solubility of the solute in water?. Background questions. What effects do solutes have on a solvent’s freezing point and boiling points? . The Basics. The brief definition of Thermodynamics is . the science concerned with the relations between heat and mechanical energy or work, and the conversion of one into the other: modern thermodynamics deals with the properties of systems for the description of which temperature is a necessary coordinate. D. etermination of ΔH. ° and ΔS° . Borax. Borax has the formula Na. 2. [B. 4. O. 5. (OH). 4. ].8H. 2. O. [B. 4. O. 5. (OH). 4. ]. 2-. is the tetra-borate anion.
