  • Solubility - 2656 Words
    Solubility and Functional Groups _______________________________________________________ You will recall from general chemistry that a solution has two components: the solvent, which is the substance present in greater amount, and the solute, which is dissolved in the solvent. Solubility is defined as the mass (in grams) of solute dissolved in 100 g of solute at saturation. Molar solubility is defined as the amount (in moles) of solute per liter of saturated solution. The solubility of one...

  • solubility - 357 Words
    A supersaturated solution is a solution that contains more dissolved substance than a saturated solution does. This occurs when a solution is prepared at a higher temperature and is then slowly cooled. This is a very unstable situation, so any disturbance causes precipitation. Solubility can be understood in terms of two factors: The natural tendency toward disorder favors dissolving. The relative forces between and within species must be considered. Stronger forces within solute...

    factors affecting solubility 1. Effect of Temperature For some substances to dissolve in a given solvent, heat is absorbed. The reaction is endothermic. In this case, an increase in temperature increases solubility. For some substances, heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case, an increase in temperature decreases solubility. Generally, an increase in temperature in the solubility of solids in liquids increases solubility. But for...

    Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant, Ksp, of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated...

    Purpose: To observe the reactions of specific aqueous solutions with specific aqueous reagents. Introduction: A solution is as a homogeneous mixture containing two or more substances. Reagents are added to solutions to create a chemical reaction or added to see if anything occurs. Reagents can be added to solutions to see if there is a presence of other substances. For example, iodine added to a lead solution. Iodine would be the reagent and would cause a chemical reaction confirming the...

    1. In general, solubility rules can be used to predict the outcome of double replacement reactions. I have come to this decision, because almost all of the data recorded from the lab, with the exception of number 13, agreed with the predictions made beforehand. 2. Out of the 15 combinations, the observations made for the combination of number 13 (the reaction of lead (II) nitrate and barium chloride), did not agree with what was predicted, based on the solubility rules.

  • Ionic Bond - 559 Words
    When ionic solids dissolve, they divide to give their positive and negative ions that make up the solids. These ions become hydrates and have the same relative proportions when in solution and when solid. The more the solid dissolves, the more the ion’s concentration increases. This increase and build-up allows for the reverse reaction to occur. In this phase of the reaction the ions crystallise out in order for the reaction to have a greater chance of occurring. Eventually the rate...

    Recrystallization is the most common method for purifying an organic solid. This technique relies on the fact that the solubility of an organic compound often increases greatly as the solvent is heated to boiling point. When an impure solid is heated in the appropriate solvent to dissolve it, then cooled down to decrease its solubility, it will usually crystallize in a more pure form. Ideal solvent is the one that your solid is insoluble at room temperature, but soluble in hot solvent ( at...
