PPT-Solubility and Concentration

Chapter 73 Objectives Explain the meaning of solubility and compare the solubility of various substances Describe dilute concentrated saturated unsaturated and supersaturated solutions Relate changes in temperature and pressure to changes in solubility of solid and gaseous solutes. 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:. 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. AP . Chem. Mr. Nelson. The Concept of Equilibrium. The term . reversible reaction . is used to describe reactions that can go in either the forward or the reverse direction. Equilibrium. is used to specify that a reversible reaction has reached an . 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.. 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 . Chapter 7.6. Solubility . Equilibria of . Ionic Compounds. Solubility . is . the quantity of solute that dissolves in a given quantity of solvent at a particular temperature. A . solubility equilibrium . Concentration. The amount of a specific substance in a known volume of solution. Concentrated Solutions. The amount of substance dissolved in solution is very high . It is difficult to dissolve more substance into solution. Demonstrate understanding of equilibrium principles in aqueous systems. Aqueous systems are limited to those involving sparingly soluble ionic solids and acidic and basic solutions (in which proton transfer occurs). . 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. . Get out your Saccharine-y Sweet Solutions lab. Get . out EOC sheet, notes, and review packet. PHYSICAL SCIENCE PS52. Match the following elements with the category or series to which they belong:. C, N, O, P, S, Se. James F. Kirby. Quinnipiac University. Hamden, CT. Lecture Presentation. © 2015 Pearson Education, Inc.. Effect of Acetate on the Acetic Acid Equilibrium. Acetic acid is a weak acid:. CH. 3. COOH(. aq. Many solids and gases dissolve in water. As you increase the temperature, you can dissolve more solid. Does this work the same with gas?. NO – as you increase temp, gas molecules KE !. Where can you go to find if something is soluble or insoluble in water?.  .  . FR-22 / IAEA, VIENA. Loginov. Nikolai . Ivanovich. , . Vereshchagina. Tatyana . Nikolaevna. General Scientist, General Scientist. Introduction. Plug indicators (PI) of . impurities . in sodium are used . Solutions are classified as mixtures.. The a. mounts of substances mixed (solute and solvent) can vary in different solutions.. Concentration. is a way of communicating how much solute is dissolved into a given amount of solution..
