PPT-UNIT 10: SOLUTIONS AND SOLUBILITY

Introductions to Solutions 1 Solution 2 Solute 3 Solvent 4 Saturated 5 Unsaturated 6 Supersaturated 7 Electrolyte 8 Aqueous 9 Homogeneous 10 Heterogeneous AIM 1 How can we describe solutions. 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:. Recall, solubility is the amount of solute that dissolves in a given volume of solvent at a certain temperature. .. Solubility is determined by the intermolecular attractions between solvent and solute particles. Section 1. – Solutions and Other Mixtures. Section 2. – How Substances Dissolve. Section 3. – Solubility and Concentration. 1 - Solutions . and Other Mixtures. . Key Questions. What is a heterogeneous mixture?. 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 . 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 . Ms. Deanne Science 8. Solubility Lab. What did we learn from our lab?. What are some things we observed?. FACTORS AFFECTING SOLUBILITY. TYPE . OF SOLVENT. - Sugar will dissolve in . water. but not . 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”. A . solution. is a . mixture in which particles of one or more substances (the solute) are distributed uniformly throughout another substance (the solvent), so that the mixture is homogeneous at the molecular or ionic level.. 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. . 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?. solutions. Stage: 3/ 1st course. Dr. Ameer S. Sahib. Solutions. In pharmaceutical terms, solutions are “liquid preparations that contain one or more chemical substances dissolved in suitable solvent or mixture of mutually miscible solvents ” (aqueous or non –aqueous)..
