PPT-9.5 Dilution of Solutions

In a dilution a solvent usually water is added to a solution which increases its volume and decreases the concentration of the solution Making orange juice from concentrate is an example of a dilution . From Liquids. (More accurately, from stock solutions). Making molar solutions from liquids. Not all compounds are in a solid form. Acids are purchased as liquids (“stock solutions”). Yet, we still need a way to make molar solutions of these compounds.. An introduction to dilutions. Dilutions are fractions. When we add water to orange juice concentrate to make orange juice for breakfast, . we are making a dilution. .. The dilution that we have made can be determined by the expression:. 1 = a routinely used solution prepared in Many laboratory chemicals such as acids are purchased as concentrated solutions (stock solutions).12 M HCl18 M HMore dilute solutions are prepared by taking a Solution is a homogeneous mixture of two or more substances. . . Solute . is the dissolved substance. , whereas solvent . is a substance in which solutes dissolves to make the mixture. . There . are different types of solutions used in medical laboratory procedures. . Units of Concentration . Molality (. m. ) . aka “. molal. concentration”. . Solvent= does not include solute. Molarity (. M. ) . aka “molar concentration”. Most common concentration unit in Chemistry. SOLUTIONS & CONCENTRATIONS. WHAT IS A SOLUTION ?. WHAT IS CONCENTRATION & HOW IS IT MEASURED ?. IS DISSOLVING A CHEMICAL OF A PHYSICAL PROCESS ?. IF SUGAR IS DISSOLVED IN WATER IS ITS CHEMICAL NATURE CHANGED ?. Introduction To Medical Technology. Lecture . - . 7 . Solution is a homogeneous mixture of two or more substances. . Solute is the dissolved substance, whereas solvent is a substance in which solutes dissolves to make the mixture. . Lesson 6. Concentration. Concentration:. Is a measure of the amount of substance (solute….usually solid) that exists in a volume of solution (solvent).. Concentration. The amount of solute in a solution.. Salman Ahmad. Helena . Olivieri. Purpose . To see how changing . chemostat. conditions affects cell growth. To identify a dilution rate that maximizes cell growth in relation to nutrient use in a . chemostat. Intro to Spectrophotometry. Solutions. Solution: . a homogenous mixture of two or more substances in the same phase.. Solute: . substance dissolved in another substance (the solvent). Solvent: . substance that dissolves a solute, resulting in a solution. Solution is a homogeneous mixture of two or more substances. . . Solute . is the dissolved substance. , whereas solvent . is a substance in which solutes dissolves to make the mixture. . There . are different types of solutions used in medical laboratory procedures. . Lecture 2. Preparation of Solutions. It could be prepared either from:. 1- Solid material.. 2-Liquid.. Preparation of Solutions from Solid Material. In general it follows a 4 . steps. :. Weigh . the . 3.3: Molarity. Describe the fundamental properties of solutions. Calculate solution concentration using molarity. Perform dilution calculations using the dilution equation. Solutions. Remember that . By:- Rahul Magan . Group Chief . Executive . Officer (CEO), .
