PPT-Solutions and Solubility

Understand factors that influence the choice of solvents including i water to dissolve some ionic compounds in terms of the hydration of the ions ii water to dissolve simple alcohols in terms of hydrogen bonding. Positive deviation of the enthalpy of mixing and consequently limited solid solubility may be predicted from known atomic properties.. Hume-. Rothery. - empirical rules to predict solid solubility. For solid solubility exist b/t two elements, the following settlements are always true:. 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.. Do Now: label as soluble and insoluble. 1. CH. 4. 2. . AgCl. 3. C. 12. H. 22. O. 11. 4. NaNO. 3. 5. KOH. Review: Next 3 slides. Water is often used as a solvent. Soluble = dissolves in water = . aq. Insoluble = doesn’t dissolve in water. Summer 2012. Separatory. Funnel. Separation of immiscible liquids. Extraction. To . pull out. a compound from one layer into another. A compound partitions more toward where it is more soluble (equilibrium). 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. Mineral Surfaces & Reactions. Lecture 22. Constructing stability . diagrams. This diagram shows the stability of ferrous iron minerals as a function of pH and sulfide for fixed total Fe and CO. 2. 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 . Bases. Section 2: . Solubility and Concentration. How much can dissolve?. Solubility and Concentration. SOLUBILITY. (. sol . yuh. BIH . luh. tee) is the . maximum amount of a solute . 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? . If a material is pure, it consists of only a single element or compound. If the material is impure, then it is a mixture or contains two or more elements or compounds. Do not be fooled by labels that claim their product is pure… “pure 100% orange juice”. Lesson Objectives. List examples of solutions made from different solute-solvent combinations.. List and explain three factors that affect the rate of dissolving of a solid solute in a liquid solvent.. Three Kinds of Mixtures. 1. A . solution. is an evenly-mixed mixture where you can. ’. t see its different parts. Solutions have the same properties throughout.. They can be in solid, liquid or gas form. Acids and bases are solutions. .
