NH. 3. at 10°C and 80°C. Why does solubility of NH. Solutions. Molarity (M). Is the number of moles of solute dissolved . per . Liter of solution. . Also know as molar concentration. . Unit M is read as molar. To calculate a solution’s molarity, you must know the volume of the solution and the amount of dissolved solute. Molarity The concentration of a solution is a measure of the amount of solute that is dissolved in a given quantity of solvent. – A dilute solution is one that contains a small amount of Solutions. A.  . solution.  . is a homogeneous mixture of two or more substance. A solution is generally composed of two substances. Solute: substance that is being dissolved and is in smaller quantity. Chapter 7.3. Objectives. Explain the meaning of solubility and compare the solubility of various substances.. Describe dilute, concentrated, saturated, unsaturated, and super-saturated solutions.. Relate changes in temperature and pressure to changes in solubility of solid and gaseous solutes.. 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 ?. Substance. that changes . color. in the presence of an . acid . or a . base. Red or Blue Litmus. Phenolphthalein (. phth. ). Bromothymol. blue (blue food coloring). Red cabbage juice. Episode 1102. 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. . 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. “From Scratch” Formula. Sometimes you begin making a solution from solid crystal rather than diluting an already made solution.. This is the formula you will need!. Molarity= moles of solute/liters of solution. Dr. Prem D. Sattsangi. Copyright © 2009. 1. Molar Absorptivity. Define Molar Absorptivity. Calculate the molar absorptivity with the following data. 1.25 x 10. -4. M solution has 0.45 O.D. absorbance at the . Molarity = moles of solute / Liters of solution. Concentration. ~How much solute is present in a solution compared to the solvent.. Molarity (M)- moles of solute per liter of solution. M = mol/L. 2.1 M AgNO.
